ABSTRACT

A Tropaeolum pentaphyllum Lam é uma Planta Alimentícia Não Convencional (PANC) nativa do Brasil, que está em crescente estudo. O objetivo deste trabalho foi avaliar a composição físico-química, o pH e cor da polpa da batata. Observou-se que a umidade (79,32 %), proteína (2,33%) e cinzas (0,93%), apresentaram-se semelhantes à T. pentaphyllum Lam avaliadas em outros estudos. Já os teores de carboidratos (13,02%), valor energético (82,19%) e lipídeos (3,82%) apresentaram-se superiores e de fibras (1,78%) inferiores a vegetais da mesma espécie. Além disso, a planta mostrou-se ácida, luminosa e com coloração tendendo ao vermelho e ao amarelo. Assim, percebe-se que a batata pode ser considerada um complemento alimentar pela sua composição nutricional e que é necessário a realização de mais estudos, a fim de aprimorar o conhecimento sobre a mesma.

ABSTRACT

Tropaeolum majus presents medicinal, nutritional and ornamental value. Plant extracts and fractions have been found to exhibit diuretic, antihypertensive, anti-inflammatory, antimicrobial and antioxidant activities. Moreover, protective effects on blood and liver, scurvy’s treatment, antithrombin activity and prevention against macular degeneration have also been observed. T. majus contains biologically active compounds such as flavonoids, glucosilonates, fatty acids, essential oil, chlorogenic acid, aminoacids, cucurbitacins, proteins and carotenoids. Acute and subchronic studies demonstrated a lack of toxic effects, but the extracts of this plant can have deleterious consequences during the pregnancy. The revised databases were SciELO, PubMed, ScienceDirect and Portal da Capes, considering studies between 1963 and 2014 and by searching for terms like Tropaeolum majus, Tropaeolaceae, Tropaeolum majus constituents, Tropaeolum majus use and Tropaeolum majus toxicity.


Tropaeolum majus presenta valor medicinal, alimenticio y ornamental. A partir del extracto y las fracciones de la planta se han encontrado actividades biológicas, que incluyen efecto diurético, antihipertensivo, anti-inflamatorio, antimicrobiano y antioxidante. Además, efectos protectores sobre la sangre y el hígado, tratamiento del escorbuto, actividad antitrombina y prevención contra la degeneración macular. T. majus contiene compuestos biológicamente activos como flavonoides, glucosilonates, ácidos grasos, aceite esencial, ácido clorogénico, aminoácidos, cucurbitacinas, proteínas y carotenoides. Estudios de toxicidad aguda y subcrónica demostraron una falta de efectos toxicológicos, pero los extractos de esta planta pueden tener consecuencias perjudiciales durante el embarazo. Las bases de datos revisadas fueron SciELO, PubMed, ScienceDirect y Portal da Capes, teniendo en cuenta los estudios entre 1963 y 2014 y mediante la búsqueda de términos como Tropaeolum majus, Tropaeolaceae, Tropaeolum majus constituyentes, Tropaeolum majus usos y Tropaeolum majus toxicidad.

ABSTRACT

The present investigation was designed to valuate the antiangiogenic efficacy of some local medicinal plants against liver cancer induced by diethylnitrosamine [DEN] methanolic extracts of cupressus sempervirens, chelidonium majus and tropaeolum majus were used in this study. Vascular endothelial growth factor [VEGF], alpha-Feto-protein [AFP], ferritin, alanine transaminase [ALT], aspartate transaminase [AST], Alkaline phosphatase [ALP], superoxide dismutase [SOD] and Glutathione peroxidase [GPx] were determined in blood while Nitric oxide [NO] was determined in liver tissue homogenate. Furthermore histopathological investigations ere done. The results showed that the treatment with methanolic extracts of all selected plants led to a significant reduction in the level of all the desired biochemical parameters, while the administration of cupressus sempervirens only improved the histopathological pictures of liver architecture. These results suggest a beneficial effect of these plant extracts against experimentally-induced hepatocellular carcinoma and the possible mechanism of the protective effects may be partly due to the antioxidant activity of these plants
