RESUMO

The incidence of Candida species resistant to traditional antifungal drugs is increasing globally. This issue significantly impacts patients' lives and increases healthcare expenses, confirming the need to develop novel therapeutic strategies. Recently, a thermostable trypsin inhibitor named ShTI (11.558 kDa), which has antibacterial effects on Staphylococcus aureus, was isolated from Salvia hispanica L. (chia) seeds. This study aimed to assess the antifungal effect of ShTI against Candida species and its synergism with fluconazole and to evaluate its mode of action. Preliminary toxicological studies on mouse fibroblasts were also performed. ShTI exhibited antifungal effects against C. parapsilosis (ATCC® 22,019), C. krusei (ATCC® 6258), and six clinical fluconazole-resistant strains of C. albicans (2), C. parapsilosis (2), and C. tropicalis (2). The minimum inhibitory concentration (MIC) values were 4.1 µM (inhibiting 50% of the isolates) and 8.2 µM (inhibiting 100% of the isolates). Additionally, when combined with fluconazole, ShTI had a synergistic effect on C. albicans, altering the morphological structure of the yeast. The mode of action of ShTI against C. krusei (ATCC® 6258) and C. albicans involves cell membrane permeabilization, the overproduction of reactive oxygen species, the formation of pseudohyphae, pore formation, and consequently, cell death. In addition, ShTI (8.65 and 17.3 µM) had noncytotoxic and nongenotoxic effects on L929 mouse fibroblasts. These findings suggest that ShTI could be a promising antimicrobial candidate, but further research is necessary to advance its application as a novel antifungal agent.

RESUMO

From the aerial parts of Salvia carranzae Zamudio and Bedolla, three new icetexane-type diterpenoids were isolated. Their structures were established through spectroscopic methods and named the following: salvicarranzanolide (1), 19-deoxo-salvicarranzanolide (2) and 19-deoxo-20-deoxy-salvicarranzanolide (3). In addition, the known icetexane-type diterpenoids, 6,7,11,14-tetrahydro-7-oxo-icetexone (4), iso-icetexone (5), 19-deoxo-iso-icetexone (6), icetexone (7), 19-deoxo-icetexone (8) and 7α-acetoxy-6,7-dihydroicetexone (9), were also isolated, along with the abietanes sessein (10) and ferruginol (11). α-Tocopherol was also identified. Compounds 5, 6 and 8 were tested for their antiproliferative activity using the sulforhodamine B assay on six cancer and one normal human cell lines. Diterpenoids 5 and 6 showed noteworthy antiproliferative activity, exhibiting an IC50 (µM) = 0.43 ± 0.01 and 1.34 ± 0.04, respectively, for U251 (glioblastoma), an IC50 (µM) = 0.45 ± 0.01 and 1.29 ± 0.06 for K5621 (myelogenous leukemia), 0.84 ± 0.07 and 1.03 ± 0.10 for HCT-15 (colon cancer), and 0.73 ± 0.06 and 0.95 ± 0.09 for SKLU-1 (lung adenocarcinoma) cell lines. On the other hand, the phytotoxicity of compounds 5-7 and 9-10 was evaluated on seed germination and root growth in some weeds such as Medicago sativa, Panicum miliaceum, Amaranthus hypochondriacus and Trifolium pratense as models. While compounds 5 and 10 exhibited a moderate inhibitory effect on the root growth of A. hypochondriacus and T. pratense at 100 ppm, the diterpenoids 6, 7 and 9 were ineffective in all the plant models. Taxonomic positions based on the chemical profiles found are also discussed.

RESUMO

Salvia is a very valuable medicinal plant for the pharmaceutical industry. Tissue culture techniques can be used to increase the number of plants in a shorter time. Although protocols for in vitro propagation of more than 15 plant species have been developed, they are not yet efficient enough to increase mass propagation of plants. Therefore, the use of temporary immersion systems is necessary to increase the morphological quality of plants as well as their biomass in several Salvia species. In this chapter, progress in in vitro propagation in several Salvia species using liquid medium and automation is described.

RESUMO

Eating practices are changing due to awareness about meat consumption associated with social, ethical, environmental, and nutritional issues. Plant-based meat analogs are alternatives to conventional meat products that attempt to mimic all the inherent characteristics of meat fully. Therefore, the search for raw materials that provide these characteristics is increasing. Chia seeds have excellent potential as a functional ingredient in these products since they are a source of proteins, lipids, and fibers. Allied with this, the full use of chia through the seed and its fractions highlights the numerous beneficial characteristics of the formulation regarding nutritional characteristics and techno-functionality. Therefore, this review aims to highlight the potential of chia seed and its fractions for applications in meat-like products. Chia seeds are protein sources. Chia oil is rich in polyunsaturated fatty acids, and its application in emulsions ensures the oil's nutritional quality and maintains its technological characteristics. Defatted chia flour has a high protein content and can be used to extract chia mucilage. Due to its high emulsification capacity, chia mucilage is an effective ingredient for meat products and, consequently, meat-like products. Therefore, this literature review demonstrates the strategic potential of using chia seeds and their fractions to develop meat analogs.

RESUMO

Diabetes mellitus (DM) is considered one of the major health diseases worldwide, one that requires immediate alternatives to allow treatments for DM to be more effective and less costly for patients and also for health-care systems. Recent approaches propose treatments for DM based on that; in addition to focusing on reducing hyperglycemia, they also consider multitargets, as in the case of plants. Among these, we find the plant known as chia to be highlighted, a crop native to Mexico and one cultivated in Mesoamerica from pre-Hispanic times. The present work contributes to the review of the antidiabetic effects of chia for the treatment of DM. The antidiabetic effects of chia are effective in different mechanisms involved in the complex pathogenesis of DM, including hypoglycemic, antioxidant, and anti-inflammatory mechanisms, and the inhibition of the enzymes α-glucosidase and α-amylase, as well as in the prevention of the risk of cardiovascular disease. The tests reviewed included 16 in vivo assays on rodent models, 13 clinical trials, and 4 in vitro tests. Furthermore, chia represents advantages over other natural products due to its availability and its acceptance and, in addition, as a component of the daily diet worldwide, especially due to its omega-3 fatty acids and its high concentration of dietary fiber. Thus, chia in the present work represents a source of antidiabetic agents that would perhaps be useful in novel clinical treatments.

RESUMO

By-products from the industrialization of oilseeds, particularly chia, can be sustainably used for the development of new functional products. In this work, wheat breads supplemented with up to 10 mg of chia expeller hydrolysate/g of flour were prepared, obtaining fortified breads with acceptability for consumption, according to a preliminary consumer research study based on an affective test employing a five-point hedonic scale of global acceptance. In this context, protein hydrolysates of the chia expeller were produced using Alcalase, reaching a degree of hydrolysis of 54.3 ± 1.6% with an antioxidant activity of 55.8 ± 0.4% after 6 h incubation at 25 °C in the presence of the enzyme. These peptides showed appropriate techno-functional properties and chemical compositions suitable for the further development of bakery products. Taken together, our approach and the development of a fortified bread with plant-based bioactive peptides provide a novel and eco-friendly alternative for the recovery of nutrients from agro-industrial waste. More importantly, these enriched breads could exert beneficial effects on human health by exploiting the antioxidant properties of functional peptides derived from the chia expeller.

RESUMO

Salvia hispanica L., commonly known as chía, and its seeds have been used since ancient times to prepare different beverages. Due to its nutritional content, it is considered a dietary ingredient and has been reported with many health benefits. Chia seed components are helpful in cardiovascular disease (CVD) by reducing blood pressure, platelet aggregation, cholesterol, and oxidation. Still, its vasodilator effects on the vascular system were not reported yet. The hexanic (HESh), dichloromethanic (DESh), and methanolic (MESh) extracts obtained from chía seeds were evaluated on an aortic ring ex-vivo experimental model. The vasorelaxant efficacy and mechanism of action were determined. Also, phytochemical data was obtained through 13C NMR-based dereplication. The MESh extract showed the highest efficacy (Emax = 87%), and its effect was partially endothelium-dependent. The mechanism of action was determined experimentally, and the vasorelaxant curves were modified in the presence of L-NAME, ODQ, and potassium channel blockers. MESh caused a relaxing effect on KCl 80 mM-induced contraction and was less potent than nifedipine. The CaCl2-induced contraction was significantly decreased compared with the control curve. Phytochemical analysis of MESh suggests the presence of mannitol, previously reported as a vasodilator on aortic rings. Our findings suggest NO-cGMP pathway participation as a vasodilator mechanism of action of S. hispanica seeds; this effect can be attributed, in part, to the mannitol presence. S. hispanica could be used in future research focused on antihypertensive therapies.

RESUMO

Cancer is one of the leading causes of death worldwide. Conventional cancer therapies are not selective to cancer cells resulting in serious side effects on patients. Thus, the need for complementary treatments that improve the patient's response to cancer therapy is highly important. To predict and evaluate the physicochemical characteristics and potential anticancer activity of the peptides identified from S. hispanica protein fraction <1 kDa through the use of in silico tools. Peptides derived from Salvia hispanica's protein fraction <1 kDa were identified and analyzed for the prediction of their physicochemical properties. The characterized peptide sequences were then submitted to a multi-criteria decision analysis to identify the peptides that possess the characteristics to potentially exert anticancer activity. Through molecular docking analysis, the potential anticancer activity of the Potentially Anticancer Peptide (PAP)-1, PAP-2, PAP-3, PAP-4, and PAP-5 was estimated by their binding interactions with cancer and apoptosis-related molecules. All five evaluated PAPs exhibited strong binding interactions (< -100 kcal/mol). However, PAP-3 showed the lowest binding free energies with several of the targets. Thus, PAP-3 shows potential to be used as a nutraceutical or ingredient for functional foods that adjuvate in cancer treatment. Conclusions: Through the molecular docking studies, the binding of the PAPs to target molecules of interest for cancer treatment was successfully simulated, from which PAP-3 exhibited the lowest binding free energies. Further in vitro and in vivo studies are required to validate the predictions obtained by the in silico analysis.Communicated by Ramaswamy H. Sarma.

RESUMO

Salvia aratocensis (Lamiaceae) is an endemic shrub from the Chicamocha River Canyon in Santander (Colombia). Its essential oil (EO) was distilled from the aerial parts of the plant via steam distillation and microwave-assisted hydrodistillation and analyzed using GC/MS and GC/FID. Hydroethanolic extracts were isolated from dry plants before distillation and from the residual plant material after distillation. The extracts were characterized via UHPLC-ESI(+/-)-Orbitrap-HRMS. The S. aratocensis essential oil was rich in oxygenated sesquiterpenes (60-69%) and presented τ-cadinol (44-48%) and 1,10-di-epi-cubenol (21-24%) as its major components. The in vitro antioxidant activity of the EOs, measured via an ABTS+• assay, was 32-49 µmol Trolox® g-1 and that measured using the ORAC assay was 1520-1610 µmol Trolox® g-1. Ursolic acid (28.9-39.8 mg g-1) and luteolin-7-O-glucuronide (1.16-25.3 mg g-1) were the major S. aratocensis extract constituents. The antioxidant activity of the S. aratocensis extract, obtained from undistilled plant material, was higher (82 ± 4 µmol Trolox® g-1, ABTS+•; 1300 ± 14 µmol Trolox® g-1, ORAC) than that of the extracts obtained from the residual plant material (51-73 µmol Trolox® g-1, ABTS+•; 752-1205 µmol Trolox® g-1, ORAC). S. aratocensis EO and extract had higher ORAC antioxidant capacity than the reference substances butyl hydroxy toluene (98 µmol Trolox® g-1) and α-tocopherol (450 µmol Trolox® g-1). S. aratocensis EOs and extracts have the potential to be used as natural antioxidants for cosmetics and pharmaceutical products.

RESUMO

The increase in the preference for vegan and vegetarian diets is directly related to changing eating habits and the need for plant-based alternatives to animal-based products, which are better for health, due to the high content of essential amino acids and lipid profile rich in polyunsaturated fatty acids, and have lower environmental impacts. In this scenario, there is a growing demand for plant-based foods, making it necessary to find new plant-based ingredients for application in foods and beverages. Flaxseed, chia seed, and Barbados gooseberry contain mucilage, a component with potential application in plant-based products. These hydrocolloids can be used as gelling agents, texture modifiers, stabilizers, and emulsifiers in solid and semi-solid foods. This review presents the extraction, characterization, and application of flaxseed, chia seed, and Barbados gooseberry mucilage for use in plant-based foods. It was found that mucilage composition varies due to the extraction method used, extraction conditions, and geographic location of the seed or leaf. However, applications in plant-based foods are currently limited, mainly focused on applying chia mucilage in bakery products and packaging. Research on applying flaxseed and Barbados gooseberry mucilage to plant-based products is limited, though it has been shown to have potential applications in packaging. Mucilage may also increase the nutritional profile of the product and provide better technological, functional, and sensory characteristics. Therefore, because of mucilage's excellent functional and technological properties, it is a promising candidate to act as an ingredient in plant-based food products.

RESUMO

Obesity is a significant health concern affecting 13% of the world's population. It is often associated with insulin resistance and metabolic-associated fatty liver disease (MAFLD), which can cause chronic inflammation in the liver and adipose tissue. Obese hepatocytes show increased lipid droplets and lipid peroxidation, which can lead to the progression of liver damage. Polyphenols have been shown to have the ability to reduce lipid peroxidation, thereby promoting hepatocyte health. Chia leaves, a by-product of chia seed production, are a natural source of bioactive antioxidant compounds, such as cinnamic acids and flavonoids, which have antioxidant and anti-inflammatory properties. In this study, chia leaves' ethanolic extracts of two seed phenotypes were tested on diet-induced obese mice to evaluate their therapeutic potential. Results show that the chia leaf extract positively affected insulin resistance and lipid peroxidation in the liver. In addition, the extract improved the HOMA-IR index compared to the obese control group, reducing the number and size of lipid droplets and lipid peroxidation. These results suggest that chia leaf extract may help treat insulin resistance and liver damage associated with MAFLD.

RESUMO

In this study, the effects of altitude and soil properties on the essential oil amounts and essential oil components of the Turkish sage (Salvia fruticosaMill.) plant were investigated. A location in the south of Turkey in the Kas district of Antalya with altitude ranges of 0-200 m, 300-500 m, and 600-800 m was defined as the study area. During the full flowering period of S. fruticosa, plants and soil samples were collected. The contents of the essential oils of the plants were analyzed using GC-MS. According to the results obtained, the essential oil content of plants varied between 1.91% and 5.10%. The main component of the essential oils of the plants collected from all study areas was 1,8-cineol, at 44.93%. It was concluded that variations in the proportions of the components limonene and linalool, which are essential oil components of plants, are not only dependent on altitude but also on changes in soil texture and the total CaCO3 content of the soil.


En este estudio, se investigaron los efectos de la altitud y las propiedades del suelo sobre las cantidades de aceite esencial y los componentes del aceite esencial de la planta de salvia turca (Salvia fruticosa Mill). Se definió como área de estudio una ubicación de 300-500 m a 600-800 m en el sur de Turquía en el distrito de Kas de Antalya con rangos de altitud de 0-200 m. Durante el período de plena floración de S. fruticosa, se recolectaron plantas y muestras de suelo. El contenido de los aceites esenciales de las plantas se analizó mediante GC-MS. Según los resultados obtenidos, el contenido de aceite esencial de las plantas varió entre el 1,91% y el 5,10%. El componente principal de los aceites esenciales de las plantas recolectadas de todas las áreas de estudio fue el 1,8-cineol, al 44,93%. Se concluyó que las variaciones en las proporciones de los componentes limoneno y linalol, que son componentes del aceite esencial de las plantas, no solo dependen de la altitud sino también de los cambios en la textura del suelo y el contenido total de CaCO3 del suelo.

RESUMO

A recent article by Kriebel et al. (2020) examines the relationship between floral shape evolution and pollination shifts in Salvia, a plant genus almost worldwide distributed, but particularly diverse in the New World. Kriebel et al. (2020) argue that a major shift to bird pollination at the origin of the subg. Calosphace (~20 million years ago [Mya]) imposed a legacy of constraints, resulting in significant differences in flower morphology between New World and Old World Salvia. However, reanalyses of the data using hidden states to account for the heterogeneity in evolutionary rates do not support an early origin of bird pollination in this group. Instead, bird pollination may have appeared after the arrival of modern hummingbirds to North America (15.5-12 Mya), as in other North American plant clades. The use of more complex models of ancestral state reconstruction into comparative analyses provides a different perspective to explain morphological differences within Salvia. Our results indicate that bird pollination did not impose constraints on corolla shape evolution. Evolutionary constraints in anther connective and style shapes may have arisen at the origin of Calosphace but they were not associated with shifts to hummingbird pollination, being more likely the product of contingent evolution.

RESUMO

BACKGROUND: Obesity is an epidemic, multifactorial and difficult-to-control disease, besides being a risk factor for cardiovascular diseases. Among the multiple intervention proposals, the addition of chia in meals has been considered due to its composition and possible effects on weight loss and cardiovascular parameters. OBJECTIVE: We evaluate the influence of chia flour (Salvia hispanica L.) intake on body weight, body composition, energy expenditure (EE) and cardiovascular risk in obese women. METHODS: This study is a clinical trial performed with 20 adult women with obesity randomized into experimental (chia flour) and control (placebo) groups. We assessed anthropometric and biochemical measurements, as well as clinical, dietary and EE variables before intervention and 90 days later. RESULTS: There were no differences in anthropometric indicators, body composition or EE between groups, but a decrease in HDL-c (p = 0.049) and a trend towards the reduction of systolic blood pressure (SBP) (p = 0.062) was observed in the experimental group. CONCLUSION: Chia flour had a possible positive effect on SBP control, but negatively affected the lipid profile and did not seem to influence obesity control.

RESUMO

Salvia mellifera, native to California, Baja California, and Mexico, is a medicinal herb traditionally used to relieve pain, body aches, including chronic pain. A detailed phytochemical investigation of aerial parts of S. mellifera was accomplished to find species-specific markers and to differentiate the closely related, often (un)intentionally substituted with S. apiana. A total of 22 metabolites, including flavonoids (1-14), triterpenoids (15-18), diterpenoids (19-21), and phenylpropanoid (22), were isolated and characterized thoroughly. Among the isolates, eupatorin 3'-O-glucopyranoside (1) was identified as undescribed phytochemical and detailed structure elucidation was achieved through extensive NMR and mass spectral data analysis.

RESUMO

Melanoma is the most aggressive and lethal type of skin cancer, characterized by therapeutic resistance. In this context, the present study aimed to investigate the cytotoxic potential of manool, a diterpene from Salvia officinalis L., in human (A375) and murine (B16F10) melanoma cell lines. The analysis of cytotoxicity using the XTT assay showed the lowest IC50 after 48 h of treatment with the manool, being 17.6 and 18.2 µg/ml for A375 and B16F10, respectively. A selective antiproliferative effect of manool was observed on the A375 cells based on the colony formation assay, showing an IC50 equivalent to 5.6 µg/ml. The manool treatments led to 43.5% inhibition of the A375 cell migration at a concentration of 5.0 µg/ml. However, it did not affect cell migration in the B16F10 cells. Cell cycle analysis revealed that the manool interfered in the cell cycle of the A375 cells, blocking the G2/M phase. No changes in the cell cycle were observed in the B16F10 cells. Interestingly, manool did not induce apoptosis in the A375 cells, but apoptosis was observed after treatment of the B16F10 cells. Additionally, manool showed an antimelanoma effect in a reconstructed human skin model. Furthermore, in silico studies, showed that manool is stabilized in the active sites of the tubulin dimer with comparable energy concerning taxol, indicating that both structures can inhibit the proliferation of cancer cells. Altogether, it is concluded that manool, through the modulation of the cell cycle, presents a selective antiproliferative activity and a potential antimelanoma effect.

RESUMO

Three new diterpenoids, demethylfruticuline B (1), 20-hydroxyfruticuline B (2), and 6-hydroxyisofruticuline A (3) were isolated from the leaves of Salvia lachnostachys Benth, together with five known compounds: fruticuline B (4), fruticuline A (5), demethylfruticuline A (6), heterobetulinic acid (7), and maslinic acid (8). The known compounds 7-8 are being reported for the first time in this species. Compounds 1 and 4-6 were tested for antioxidant activity using the ORAC-FL method, and the antioxidant capacity was measured as relative trolox equivalent. All compounds were active, with values of relative trolox equivalent varying between 1.20-2.42. The most active compound was demethylfruticuline B (1).

RESUMO

RESUMEN La chía (Salvia hispanica L.) es una semilla originaria de la zona sur de México y Guatemala, que se ha expandido a otros países de latinoamérica. Esta semilla ha sido utilizada con diferentes fines a lo largo de la historia, donde se destaca como producto alimentario debido a su gran versatilidad, ya que puede ser utilizada como semilla, harina integral, fracciones de fibra y/o proteína y aceite. En la actualidad, la investigación de nuevas fuentes alimentarias que otorguen beneficios a la salud ha logrado recopilar información sobre la composición química y valor nutricional de esta semilla y sus derivados (harina y aceite), donde se encuentra principalmente el contenido de ácidos grasos poli-insaturados n-3, destacando el ácido alfa linolénico (C18:3n-3, ALA), que se propone como fuente alternativa de este nutriente a alimentos de otros orígenes, además el contenido de fibra de la chía, principalmente fibra insoluble. En cuanto a los beneficios que se asocian al consumo de chía, se ha visto que tiene estrecha relación con enfermedades crónicas no transmisibles como dislipidemia, diabetes, hipertensión, cáncer, entre otras, logrando captar la atención de investigadores para controlar y prevenir estas patologías que van en aumento en la población mundial. Por lo tanto, se hace relevante profundizar en los conocimientos disponibles sobre esta semilla y sus subproductos para poder establecer los posibles mecanismos moleculares que están involucrados en la generación de beneficios para la salud. El objetivo de esta revisión es presentar una actualización de los beneficios asociados al consumo de semilla de chía y sus derivados.


ABSTRACT Chia (Salvia hispanica L.) is a seed native to the southern part of Mexico and Guatemala, which has spread to other Latin American countries. This seed has been used for different purposes throughout history, where it stands out as a food product due to its great versatility, since it can be used as a seed, whole meal flour, fiber and/or protein fractions and oil. Currently, the investigation of new food sources that provide health benefits has managed to collect information on the chemical composition and nutritional value of this seed and its derivatives (flour and oil). For polyunsaturated fatty acid content, n-3 is found, highlighting alpha linolenic acid (C18:3n-3, ALA), which is proposed as an alternative source of this nutrient to foods of other origins. In addition, the fiber content of chia, is mainly insoluble fiber. Regarding the benefits associated with chia consumption, it is closely related to chronic non-communicable diseases such as dyslipidemia, diabetes, type II, hypertension, cancer, among others, managing to attract the attention of researchers to control and prevent these pathologies that are increasing in world population. Therefore, it is relevant to deepen the knowledge available about this seed and its by-products in order to establish the possible molecular mechanisms that are involved in generating health benefits. The objective of this review is to present an update on the benefits associated with consumption of chia seed and its derivatives.

RESUMO

This study describes the antimicrobial and anti-inflammatory effects from extracts obtained from the leaves of Salvia lavanduloides. The plant material was macerated with three solvents of ascending polarity (n-hexane (Sl-Hex), ethyl acetate (Sl-AcOEt), and dichloromethane (Sl-D)). The extracts, fractions (SlD-2 and SlD-3), and isolated compounds (15,16-epoxy-10-ß-hydroxy-neo-cleroda-3,7,13(16),14-tetraene-17,12R:18,19-diolide (1), salviandulin A (2), and eupatorin (3)) were evaluated as antimicrobials against Gram-negative, Gram-positive bacteria and the fungus Candida albicans (Ca) using the minimum inhibitory concentration (MIC) and the anti-inflammatory activity induced by 13-acetate of 12-O-tetradecanoylforbol (TPA). Sl-D and Sl-AcOEt extracts, SlD-2 and SlD-3 fractions showed the highest antimicrobial activity. The isolated compounds showed good activity against Pseudomonas aeruginosa with a MIC < 2 µg/mL, while the anti-inflammatory activity, the Sl-Hex, Sl-D extracts, and SlD-3 fraction presented an inhibition of 62, 45 and 61%, respectively, while (2) 70% and (3) 72%.
