ABSTRACT

Abstract Traditional medicine is cheaper and easily available to local people, to care for most frequent diseases in the Northern parts of Pakistan. Our study aimed at inventorying medicine from local plants, documenting their uses, and assessing their market value in 2015-2018 during spring, summer, and winter seasons. A total of 15 trips were made, 5 in each season. Semi-structured interviews with 165 inhabitant's age range between 20-80 years were conducted, analyzed the data is analyzed using Relative frequency of citation(RFC), Use Value(UV), Fidelity Level(FL), Informants consensus factor(ICF), and Jaccard index(JI) to find the most frequent and well-known used species in the area. A total of 86 species belonging to 39 vascular plant families, 33 genera were documented as medicinally important. Family Asteraceae was observed as the dominant family among all the families with 10 species, the leaf was the most used parts and decoction 36% was the most preferred preparation type. Herb was the predominant life form (67%). The maximum UV (0.92) was demonstrated by J. adhatoda L. species, while A. sativum L. shows maximum RFC (0.58), the highest ICF value represented by diarrhea and dermatitis 0.92, and high FL value is recorded 100%. According to our collections, wild species were 45%, invasive species were 38% and cultivated 17% recorded, dicots species were recorded more 81%. Seven 7 medicinal species is being economically important and export to the local and international market of the world, whereas P. integrima L. species were the most exported species according to the local dealers. The investigated area is rural and the local people depend on the area's plants for their health needs, and other uses like a vegetable, fuelwood, fodder, etc. The current result of RFC, UV, ICF, FL, and JI shows that medicinal flora needs to be pharmacologically and phytochemically investigated to prove their efficacy. The documentation of medicinal knowledge is important to preserve this precious old knowledge before it is lost forever, due to technological and environmental changes in the world.


Resumo A medicina tradicional é mais barata e facilmente disponível à população local para cuidar das doenças mais frequentes nas áreas do norte do Paquistão. Nosso estudo teve como objetivo inventariar medicamentos de plantas locais, documentar seus usos e avaliar seu valor de mercado em 2015-2018 durante as temporadas de primavera, verão e inverno. Foram feitas 15 viagens, 5 em cada temporada. Foram realizadas entrevistas semiestruturadas com 165 moradores na faixa etária de 20 a 80 anos, com dados analisados ​​por meio de frequência relativa de citação (RFC), valor de uso (UV), nível de fidelidade (FL), fator de consenso de informantes (CIF), e o índice de Jaccard (JI) para encontrar as espécies utilizadas mais frequentes e conhecidas na área. Um total de 86 espécies pertencentes a 39 famílias de plantas vasculares, 33 gêneros foram documentados como medicamente importantes. A família Asteraceae foi observada como a família dominante entre todas as famílias com 10 espécies, a folha foi a parte mais utilizada e a decocção 36% foi o tipo de preparação mais preferido. A erva foi a forma de vida predominante (67%). O UV máximo (0,92) foi demonstrado pelas espécies de J. adhatoda L., enquanto A. sativum L. mostra RFC máximo (0,58), o maior valor de ICF representado por diarreia e dermatite 0,92, e alto valor de FL é registrado 100%. De acordo com nossas coleções, as espécies selvagens foram 45%, as espécies invasoras 38% e as cultivadas 17% registradas, as espécies dicotiledôneas foram registradas mais 81%. Sete espécies medicinais estão sendo economicamente importantes e exportadas para o mercado local e internacional do mundo, enquanto as espécies de P. integrima L. foram as espécies mais exportadas de acordo com os comerciantes locais. A área investigada é rural e a população local depende das plantas da área para suas necessidades de saúde e outros usos como vegetal, lenha, forragem etc. O resultado atual de RFC, UV, ICF, FL e JI mostra que a flora medicinal precisa ser investigada farmacológica e fitoquimicamente para comprovar sua eficácia. A documentação do conhecimento medicinal é importante para preservar esse precioso conhecimento antigo antes que se perca para sempre, devido às mudanças tecnológicas e ambientais do mundo.

ABSTRACT

Mesmo com a evolução do conhecimento científico, a utilização de plantas medicinais é uma das práticas mais antigas ainda realizadas pelo homem, especialmente pelos habitantes de comunidades e municípios do interior do Brasil, principalmente em regiões com baixos índices de desenvolvimento humano. O objetivo deste trabalho foi realizar um estudo etnobotânico sobre as plantas medicinais utilizadas pelos moradores de um bairro localizado em um município ribeirinho do interior do estado do Amazonas. Participaram do estudo cem indivíduos, e os dados obtidos pela pesquisa foram compilados por meio de um formulário, contendo 14 questões (objetivas e discursivas). Os resultados demonstraram que 95% dos moradores faziam uso de plantas medicinais. Foram citadas 89 espécies, pertencentes a 48 famílias botânicas, com destaque para a Lamiaceae. As plantas mais citadas foram: Plectranthus barbatus (boldo) ­ 6,1%, Citrus sinensis (laranjeira) ­ 5,8% e Allium sativum (alho) ­ 4,7%. No entanto, quando analisado o índice de concordância (porcentagem de uso principal = CUP), a Citrus sinensis (laranjeira) apresentou um CUP de 80,9%, seguida por Plectranthus barbatus (boldo) e Disphania ambrosioides (mastruz), com 68,1% e 61,5%, respectivamente. Com relação ao modo de preparo, 61,1% citaram infusão, e as principais enfermidades tratadas foram as dores de estômago, com 13,1%. É importante enfatizar a necessidade de mais estudos acerca dos reais benefícios dessas ervas, a fim de que a divulgação de tais informações possa complementar o conhecimento empírico já difundido entre a população local. Dessa forma, será possível ampliar o conhecimento etnobotânico como um todo e, consequentemente, promover saúde e bem-estar.


Despite the evolution of scientific knowledge, the use of medicinal plants is one of the oldest practices still used by men and, especially by the inhabitants of communities and municipalities of the interior of Brazil, mainly in regions with low human development rates. The purpose of this work was to perform an ethnobotanical study on medicinal plants used by residents of a neighborhood located in a riverside city in the interior of the state of Amazonas. A total of 100 individuals participated in the study, with data being obtained through the use of a form containing 14 open and closed-ended questions. The results showed that 95% of the residents used medicinal plants. A total of 89 species, belonging to 48 botanical families were mentioned, with emphasis to Lamiaceae. The plants that were most frequently mentioned were Plectranthus barbatus (locally known as boldo) ­ 6.1%; Citrus sinensis (orange tree) ­ 5.8%; and Allium sativum (garlic) ­ 4.7%. However, when analyzing the agreement index (percentage of main use = CUP), Citrus sinensis (orange tree) presented a CUP of 80.9%, followed by Plectranthus barbatus (boldo) and Disphania ambrosioides (Mexican tea), with 68.1 and 61.5%, respectively. In relation to the method of preparation, 61.1% cited infusion, with the main disorder treated being stomachache, with 13.1%. It is important to emphasize the need for further studies on the actual benefits of these herbs so that the dissemination of the information can complement the already widespread empirical knowledge among the local population. Thus, it will be possible to expand the ethnobotanical knowledge as a whole and, consequently, promote health and well-being.

ABSTRACT

Background: Coronavirus infectious disease 2019 (COVID-19) caused by the infection with the new coronavirus SARS-CoV-2 has affected the life and health of more than 222 million people. In the absence of any specific pharmacological treatment, the need to find new therapeutic alternatives is clear. Medicinal plants are widely used worldwide to treat different conditions, including COVID-19; however, in most cases, there are no specific studies to evaluate the efficacy of these treatments. Objective: This article evaluates the antiviral effect of six plant extracts used by indigenous and afro Colombian people against SARS-CoV-2 in vitro. Methods: The antiviral effect of six extracts prepared from plants used in Colombian traditional medicine was evaluated against SARS-CoV-2 through a pre-post treatment strategy on the Vero E6 cell line. Once cytotoxicity was established through an MTT assay, the antiviral effect of the extracts was calculated based on the reduction in the viral titer determined by plaque assay. Results:Gliricidia sepium inhibited SARS-CoV-2 in a 75.6%, 56.8%, 62.5% and 40.0% at 10 mg/mL, 8 mg/mL, 6 mg/mL, and 2 mg/mL, respectively, while Piper tuberculatumtreatment reduced viral titer in 33.3% at 6 mg/mL after 48h. Conclusion:G. sepium and P. tuberculatum extracts exhibit antiviral activity against SARS-CoV-2 in vitro

ABSTRACT

Abstract An ethnobotanical study was conducted to document indigenous medicinal plants and their usage from knowledgeable and elderly persons in Razzar and Gadoon valley of Swabi and Allai and Tanawal valley of Hazara region of Pakistan during 2016-2019. Several systematic field visits and questionnaire surveys were carried out in selected sites of the study area to gather relevant information from the local community. Rapid assessment method was adopted for data collection by interviewing the local people having enough knowledge of medicinal plants use for treatment of different ailments. UV (UV) formula was applied to calculate the relative importance of medicinal plant species in each site of the study area. In the present study, 221 medicinal plants belonging to 105 families have been reported through 580 respondents (385 males, 138 females and 57 local health healer) from the Swabi and Hazara region. The main sources of herbal medicines were leaves (21%) followed by fruits (21%), seeds (17%), whole plants (14%), roots (9%), bark (9%), flowers (7%) and gum (2%). Mentha spicata L. and Berberis lycium Royle were reported with highest UV (UV) i.e. 0.92 and 0.68 in Razzar tehsil and Gadoon valley of Swabi, whereas Mentha longifolia L and Geranium wallichianum D were reported with highest UV i.e. (0.65) and (0.88) in Allai and Tanawal valley of Hazara region, respectively. It was concluded that Swabi and Hazara region is rich in medicinal plants species and associated traditional knowledge. Moreover, ethno-medicines have played significant role in the indigenous healthcare system of the study area. However, uprooting the entire plant for ethno-medicine is a big threat to conservation of medicinal plants diversity in the study area.


Resumo Um estudo etnobotânico foi realizado para documentar as plantas medicinais indígenas e seu uso por pessoas experientes e idosas em Razzar e Gadoon, no vale de Swabi e no vale Allai e Tanawal da região de Hazara, no Paquistão, durante 2016 a 2019. Várias visitas sistemáticas de campo e pesquisas por questionário foram realizadas em locais selecionados da área de estudo para coletar informações relevantes da comunidade local. O método de avaliação rápida foi adotado para a coleta de dados por meio de entrevistas com a população local, com conhecimento suficiente do uso de plantas medicinais para o tratamento de diferentes enfermidades. A fórmula UV (UV) foi aplicada para calcular a importância relativa das espécies de plantas medicinais em cada local da área de estudo. No presente estudo, 221 plantas medicinais pertencentes a 105 famílias foram relatadas por 580 entrevistados (385 homens, 138 mulheres e 57 curandeiros locais) da região de Swabi e Hazara. As principais fontes de medicamentos fitoterápicos foram folhas (21%), seguidas de frutas (21%), sementes (17%), plantas inteiras (14%), raízes (9%), cascas (9%), flores (7%) e goma (2%). Mentha spicata L. e Berberis lycium Royle foram relatados com maior UV (UV), ou seja, 0,92 e 0,68 em Razzar tehsil e vale Gadoon de Swabi, enquanto Mentha longifolia L. e Geranium wallichianum D. foram relatados com maior UV, isto é, 0,65 e 0,88 no vale Allai e Tanawal da região de Hazara, respectivamente. Concluiu-se que a região de Swabi e Hazara é rica em espécies de plantas medicinais e conhecimentos tradicionais associados. Além disso, etnomedicamentos têm desempenhado um papel significativo no sistema de saúde indígena da área de estudo. No entanto, arrancar a planta inteira para etnomedicina é uma grande ameaça à conservação da diversidade de plantas medicinais na área de estudo.

ABSTRACT

Introducción: revalorizar y resignificar la identidad de los saberes tradicionales en salud es retador, en una cultura mediada por la industrialización, perviviendo con un pasado histórico, patrimonial cultural y simbólico, desde una identidad mixturada que se conjuga en un sincretismo territorial, que persiste a través de huellas físicas y culturales de tradiciones mágico religiosas. Objetivo: reconocer las particularidades etnográficas de los agentes portadores de saberes populares en salud que les permite afianzar sus prácticas en el municipio de Andes- Antioquia. Y resignificar estas prácticas para recuperar sus entornos identitarios y rituales simbólicos, en la configuración de su identidad como cuerpo orgánico en los espacios sociales. Metodología: investigación cualitativa, de tipo descriptivo, con perspectiva etnográfica (microetnográfica), sistematizada a través de entrevistas a profundidad acompañadas de registros fotográficos y observaciones participantes. Resultados: se reconocen 48 agentes sociales entre 30 y 70 años, la mayoría asentados en la ruralidad. Entre ellos: sobanderos con secreto, sobanderos con dolor o componedores, hierbateros y rezanderos. Se reconoce su identidad diversa desde una emergencia mágica religiosa y se exponen las características de sus saberes heredados, en una ritualidad envolvente que los recrea y vitaliza en los espacios sociales. Discusión: se analizan los resultados en el marco del espacio social, multidimensional y complejo, a través de sus tres elementos: estructuras sociales, relaciones sociales y formas espaciales. Conclusiones: las formas espaciales trasladan el simbolismo al espacio social físico con características que afianzan el ejercicio de su saber y su identidad. La brecha entre los conocimientos occidentales y los saberes tradicionales se cierra cada vez más por la fuerza de sus realidades en la vida cotidiana, de una sociedad globalizada.


Introduction: revaluing and re-signifying the identity of traditional health knowledge is challenging in a culture mediated by industrialization, surviving with a historical past, cultural and symbolic heritage, from a mixed identity that is conjugated in a territorial syncretism, which persists through physical and cultural traces of magical-religious traditions. Objective: to recognize the ethnographic particularities of the agents who carry popular knowledge in health that allows them to strengthen their practices in the Andes-Antioquia municipality. To re-signify these practices to recover their identity and symbolic ritual environments, in the configuration of their identity as an organic body in social spaces. Methodology: qualitative, descriptive type research, with ethnographic perspective (micro-ethnographic), systematized through in-depth interviews, accompanied by photographic records and participant observations. Results: 48 social agents between 30 and 70 years old, most of them settled in rural areas, were identified. Among them: sobanderos with secret, sobanderos with pain or componedores, hierbateros and rezanderos. Their diverse identity is recognized from a magical religious emergence and the characteristics of their inherited knowledge are exposed, in an enveloping rituality that recreates and vitalizes them in social spaces. Discussion: the results are analyzed within the framework of social, multidimensional and complex spaces, through its three elements: social structures, social relations and spatial forms. Conclusions: spatial forms transfer symbolism to the physical social space with characteristics that strengthen the exercise of their knowledge and identity. The gap between western knowledge and traditional knowledge is closing more and more due to the strength of its realities in the daily life of a globalized society.


Introdução: revalorizar e resignificar a identidade dos conhecimentos tradicionais em saúde é um desafio em uma cultura mediada pela industrialização, sobrevivendo com um passado histórico, cultural e simbólico, a partir de uma identidade mista de sincretismo territorial, que persiste através de traços físicos e culturais de tradições mágico-religiosas. Objetivo: reconhecer as particularidades etnográficas dos agentes portadores de conhecimentos populares em saúde que lhes permitam fortalecer suas práticas no município de Andes, Antioquia. E resignificar estas práticas a fim de recuperar seus espaços de identidade e rituais simbólicos, na configuração de sua identidade como um corpo orgânico em espaços sociais. Metodologia: pesquisa qualitativa, descritiva, com uma perspectiva etnográfica (microetnográfica), sistematizada através de entrevistas em profundidade acompanhadas de registros fotográficos e observações dos participantes. Resultados: Foram identificados 48 agentes sociais entre 30 e 70 anos de idade, a maioria deles instalados em áreas rurais. Entre eles: sobanderos com secreto, sobanderos com dor ou componedores, herboristas e curandeiros. Sua identidade diversificada é reconhecida a partir de uma emergência mágica religiosa e as características de seus conhecimentos herdados são expostas, em um ritual envolvente que os recria e os vitaliza nos espaços sociais. Discussão: os resultados são analisados no âmbito do espaço social, multidimensional e complexo, através de seus três elementos: estruturas sociais, relações sociais e formas espaciais. Conclusões: As formas espaciais traduzem o simbolismo em espaço social físico com características que fortalecem o exercício de seu conhecimento e identidade. A distância entre o conhecimento ocidental e o conhecimento tradicional está se fechando cada vez mais devido à força de suas realidades na vida cotidiana em uma sociedade globalizada.

ABSTRACT

The aim of this research was conducted an ethnobotanical study of wild asteraceas for medicinal use in two Andean communities of southern Peru, located in Quinua (Ayacucho) and Lircay (Huancavelica) districts. Samples of Asteraceae family were collected and semistructured interviews were conducted to 191 informants (105 in Quinua and 86 in Lircay). Likewise, the cultural importance of each of the species was calculated. 28 genera and 44 species of medicinal wild asteraceae are registered in both communities; 33 species in Quinua and 35 in Lircay. All the species were classified within 18 medicinal subcategories, being the affections of the digestive and genitourinary system which presented the highest number of species and use reports. The Asteraceae of greater cultural importance for both communities is Ambrosia arborescens "marko". The main conclusión is that communities studied still maintain the medicinal use of asteraceas until today.

ABSTRACT

Cataia es una Myrtaceae de gran potencial aromático y medicinal. En la costa de Paraná hay registro de uso comercial creciente de sus hojas en la aromatización de aguardiente. Buscando comprender mejor la explotación de cataia desde una perspectiva histórica, así como elucidar el conocimiento ecológico de los moradores acerca del manejo, se presentan los resultados de una investigación etnobotánica realizada en Barra do Ararapira (PR/Brasil). La recolección de datos ha incluido entrevistas semiestructuradas y acompañamiento a campo de los extractivistas. Se ha revelado potencial de sostenibilidad, denotado por el apoyo institucional, en lo que se refiere a conferir legalidad a la actividad. La baja demanda actual se presenta como punto positivo, con la necesidad de monitoreo continuo de posibles daños, frente al posible aumento de la demanda. Sobre la cadena de valor, la inexistencia de intermediarios y la venta regular a comerciantes, caracterizan un componente de comercialización favorable.


Cataia is a Myrtaceae of great aromatic and medicinal potential. On the coast of Paraná there is a record of increasing commercial use of its leaves in the aromatization of brandy. In order to better understand the exploitation of cataia from a historical perspective, as well as elucidate the ecological knowledge of the inhabitants about the management, the results of an ethnobotanical investigation carried out in Barra do Ararapira are presented. Data collect has involved individual and group interviews and monitoring of all extractor's activities. It was elucidated a sustainability potential, denoted at first instance by institutional support to confer legality to the activity and for their implementation, and the community organizational capacity. As regards to the ecological question, the low demand now existent was considerate a positive aspect, but is highlight the importance of a continuous monitoring of possible damage.

ABSTRACT

Culantro de monte (Eryngium foetidum L.) is a biennial herb of tropical origin very frequent in America, Africa and the Caribbean. With the arrival of Europeans in the fifteenth century, it managed to be distributed to various locations in Asia and Europe. The present study was carried out in the San Antonio de Padua community in the Province of Los Ríos - Ecuador to collect information, through interviews with the residents, regarding the nomenclature and uses of this aromatic herb. It was found that 52% of the interviewees mention a nutritional use, especially as a condiment for fish soup, buns and stews, while 26% say they use this plant for medicinal purposes in infusions to cure stomach and joint pain. The variety of metabolites that it possesses, such as eryngial (E-2-Dodecenal), extends its range of applications in modern medicine. We concluded that the transfer of ethnobotanical information still remains in the community, but the young generations are unaware of several of this plant's applications.


El culantro de monte (Eryngium foetidum L.) pertenece a la familia Apiaceae, es una hierba terrestre bienal de origen tropical muy frecuente en América, África y el Caribe, con la llegada de los europeos en el siglo XV, logró distribuirse a varias regiones de Asia y Europa. El presente estudio se realizó en la comunidad San Antonio de Padua en la provincia de Los Ríos ­ Ecuador, tuvo como objetivo recopilar información, mediante entrevistas escritas a los pobladores, referente a la nomenclatura y usos de esta hierba. Se encontró que un 52% de los entrevistados le da un uso culinario para preparar sopas de pescado, sancochos, bollos y estofados, mientras que un 26% dice utilizar esta planta con fines medicinales en infusiones para tratar en el ser humano dolores estomacales y dolores de las articulaciones. La variedad de metabolitos que posee, como el eryngial (E-2-Dodecenal), amplía su rango de aplicaciones en la medicina moderna. Se concluye que el flujo de información etnobotánica se mantiene en la comunidad, pero las nuevas generaciones desconocen las varias aplicaciones que tiene esta especie.

ABSTRACT

Chloroform extract (CE) and fractions obtained from Aldama arenaria roots were evaluated for their in vitro antiproliferative activity against 10 human tumor cell lines [leukemia (K-562), breast (MCF-7), ovary expressing a multidrug-resistant phenotype (NCI/ADR-RES), melanoma (UACC-62), lung (NCI-H460), prostate (PC-3), colon (HT29), ovary (OVCAR-3), glioma (U251), and kidney (786-0)]. CE presented weak to moderate antiproliferative activity (mean log GI50 1.07), whereas fractions 3 and 4, enriched with pimaranetype diterpenes [ent-pimara-8(14),15-dien-19-oic acid and ent-8(14),15-pimaradien-3ß-ol], presented moderate to potent activity for most cell lines, with mean log GI50 of 0.62 and 0.59, respectively. The results showed promising in vitro antiproliferative action of the samples obtained from A. arenaria, with the best results for NCI/ADR-RES, HT29, and OVCAR-3, and TGI values ranging from 5.95 to 28.71 µg.ml -1, demonstrating that compounds of this class may be potential prototypes for the discovery of new therapeutic agents.

ABSTRACT

The study of the relationship between man and nature can reveal the potential of plant resources. In the present study we used non-probabilistic sampling and snowball technique in communities of the Soure Marine Extractive Reserve-Pará, namely, Caju-Úna Community, Céu Settlement, and Pesqueiro Village, in order to analyze the medicinal plants used by these peoples, focusing on the diversity, consensual use and cultural importance of species, and providing ethnopharmacological information available in the scientific literature. To this end, participant observation, semi-structured interviews and free lists were used, as well as ethnobotanical indices and scientific studies retrieved from databases. We identified 90 species, among which Ruta graveolens, Maytenus obtusifolia and Libidibia ferrea stood out. The species were distributed in 50 families, mainly Lamiaceae, Asteraceae and Fabaceae. The most frequent diseases treated with these plants, mainly with preparations in the form of teas, were flu, inflammations and stomach problems. The Caju-Úna Community had the highest indices of total species diversity and evenness. Nine species stood out in the consensus factor and importance value and pharmacological studies corroborated 35% of the popular indications.

ABSTRACT

This contribution includes the registration of 70 fresh fruit species and their derivative products marketed in the Metropolitan Area of Buenos Aires, Argentina. Data on fruits and derived products were obtained from ethnobotanical fieldwork, where usual qualitative ethnobotanical methodologies were used: participant observation, free listings, open and semi-structured interviews. A bibliographic review was made on the biological activity and effects studied in order to evaluate their correspondence with the assigned local uses. The situation of invisibility/visibility of the treated species was analyzed, according to their circulation in the restricted commercial circuits (Chinese and Bolivian immigrants) and the general commercial circuit. Of the total of 70 recorded species, 62 are visible (89%) and 8 invisible (11%). These last, only found in the Barrio Chino. The registration of marketed fruits, together with their associated knowledge, represents a contribution to the study of local biocultural diversity.

ABSTRACT

Currently the weed species are a resource to conserve. The objective was to evaluate the ethnobotanical perception of the peasants about the weed flora in farms of suburban agriculture in Santiago de Cuba, Cuba. An ethnobotanical study was developed and the percentage of known species, percentage of species per management action and the percentage of weed species with potential utility was determined. The spectrum of use, the categories of use and the species richness by category were also taken into account. The weed species found in each of the farms were identified by at least 60% of the producers conferring more than 70% of this flora potential utilities such as medicinal, animal feed and agricultural. Although different forms of management for these species were identified, more than 40% are eliminated regardless of the potential benefits that productive systems can bring to this.

ABSTRACT

AIMS: This study aimed to investigate the effects of crude extract of Carica papaya leaves on oxidative stress in mice induced by cyclophosphamide, as well as phytochemical profile characterization of this extract. METHODS: The male Swiss mice received 15 days of treatment with the extract (500 mg kg-1, via gavage) and intraperitoneal injection of cyclophosphamide (75 mg kg-1) or saline (0.9%) on the 15th day. After 24 h the last treatment, the animals were anesthetized for blood withdrawal, sacrificed and removal of the organs for analyses (liver, kidney and heart). In the biochemical tests were determined: hematological parameters in blood, aminotransferases, alkaline phosphatase, glucose and total cholesterol dosages in plasma, enzymatic and non-enzymatic antioxidants and lipid damage marker were evaluated in different tissues, besides genotoxic and histopathological analyzes. RESULTS: In the extract of Carica papaya leaves, the flavonoids quercetin-3ß-D-glucoside and rutin were identified, besides present positive results for alkaloids, saponins and tannins. This extract increased the activity of glutathione-S-transferase and catalase enzymes in the liver and reduced the levels of reduced glutathione in the kidneys and hematocrit levels, red cell count, and hemoglobin. It promoted the decrease of the reactive species of thiobarbituric acid (TBARS) in the kidneys and the activity of enzyme aspartate aminotransferase in the plasma and was antimutagenic in the micronucleus test. CONCLUSIONS: The study showed that extract of Carica papaya was beneficial against oxidative events and prevented DNA damage. The extract also showed hepatotoxicity, therefore prolonged infusion of papaya leaves is not advisable.


OBJETIVOS: O objetivo deste estudo foi investigar os efeitos do extrato bruto de folhas de Carica papaya sobre o estresse oxidativo em camundongos induzidos pela ciclofosfamida, bem como a caracterização do perfil fitoquímico deste extrato. MÉTODOS: Os camundongos Swiss machos receberam 15 dias de tratamento com o extrato (500 mg kg-1, via gavagem) e injeção intraperitoneal de ciclofos-famida (75 mg kg-1) ou salina (0,9%) no 15º dia. Após 24 h do último tratamento, os animais foram anestesiados para retirada do sangue, sacrificados e retirada dos órgãos para análises (fígado, rim e coração). Nos testes bioquímicos foram determinados: parâmetros hematológicos em sangue, aminotransferases, fosfatase alcalina, dosagens de glicose e colesterol total no plasma, antioxidantes enzimáticos e não enzimáticos e marcador de dano lipídico foram avaliados em diferentes tecidos, além de análises genotóxicas e histopatológicas. RESULTADOS: No extrato de folhas de Carica papaya foram identificados os flavonoides quercetina-3ß-D-glicosídeo e rutina, além de resultados positivos para alcaloides, saponinas e taninos. Este extrato aumentou a atividade das enzimas glutationa-S-transferase e catalase no fígado e diminuiu os níveis de glutationa reduzida nos rins, a concentração do hematócrito, a contagem dos glóbulos vermelhos e a hemoglobina. Promoveu a diminuição das espécies reativas de ácido tiobarbitúrico (TBARS) nos rins, a atividade da enzima aspartato aminotransferase no plasma e foi antimuta-gênico no teste do micronúcleo. CONCLUSÕES: O estudo mostrou que o extrato de Carica papaya foi benéfico contra eventos oxidativos e preveniu danos no DNA. O extrato também mostrou hepatotoxicidade, portanto, a infusão prolongada de folhas de mamão não é aconselhável.

ABSTRACT

Medicinal and aromatic plants can be considered as "multifunctional plants" due to the diverse properties and ecosystem services they provide in agroecosystems. Among the latter, they regulate the populations of insect pests in crops, harboring their natural enemies. In order to determine the plant species with the greatest presence of natural enemies of Saissetia oleae in an agro-ecological crop of Olea europea, biological corridors with species of medicinal and aromatic plants were established in three sectors of the farm. The plants were collected together with the farmers of the Maipo Province and sticky pheromone traps, vacuum cleaner and entomological umbrella were used to collect the arthropods. The results indicate that Calendula officinalis, Borago officinalis, Aquilea millefolium, Linun usitatissimun, Chamaemulum nobile, Origanum vulgare, Artemisia agrotanum and Symphytum officinale are the species with the highest presence of S. oleae natural enemies identified as Coccophagussp., Metaphycus helvolus, Metaphycus lounsbury, Metaphycussp., Rhyzobius lophanthae, Scutellista caerulea.


Las plantas medicinales y aromáticas pueden ser consideradas como "plantas multifuncionales" por las diversas propiedades y servicios ecosistémicos que prestan en los agroecosistemas. entre estos últimos, regulan las poblaciones de insectos plagas en los cultivos albergando enemigos naturales de éstas con el objetivo de determinar las especies vegetales con mayor presencia de enemigos naturales de Saissetia oleae en un cultivo agroecológico de Olea europea se establecieron corredores biológicos con especies de plantas medicinales y aromáticas en tres sectores de la finca. Las plantas se colectaron junto con los agricultores de la Provincia del Maipo y para la recolección de los artrópodos se utilizaron trampas pegajosas de feromonas, aspirador y paraguas entomológico los resultados indican que Calendula officinalis, Borago officinalis, Aquilea millefolium, Linun usitatissimun, Chamaemulum nobile, Origanum vulgare, Artemisia agrotanum y Symphytum officinale son las especies con mayor presencia de enemigos naturales de S. oleae identificados como Coccophagus sp., Metaphycus helvolus, Metaphycus lounsbury, Metaphycus sp., Rhyzobius lophanthae, Scutellista caerulea.
