RESUMEN
Withania somnifera is a wild plant that shows great activity and safety against several human diseases. The current research explored the plant's chemical composition and allelopathic effects on Rumex dentatus (recipient plant). Moreover, anticancer activity is also tested against four types of human cancer cell lines. Chemical analysis of W. somnifera showed a high percentage of saponins and tannins, while glycosides, alkaloids, and flavonoids occurred in the second order. Results of the allelopathic experiments revealed significant inhibition of the R. dentatus plumule and radicle lengths as well as their relative dry weights. In addition, significant reductions in some primary metabolites of R. dentatus, like non-reducing and total sugar as well as soluble proteins, were determined. Cytotoxic potentiality of W. somnifera was also proved against four different cancer lines, namely; human hepatocellular carcinoma cell line (HepG2), human non-small cell lung cancer cell line (A549), human breast cancer cell line (MCF7), and colon cancer cell line (CaCo2) with IC50 value of about 38, 19, 27, and 24 ug/ml, respectively.
Withania somnifera é uma planta silvestre que apresenta grande atividade e segurança contra diversas doenças humanas. A presente pesquisa explorou a composição química da planta e os efeitos alelopáticos em Rumex dentatus (planta receptora). Além disso, a atividade anticancerígena também é testada contra quatro tipos diferentes de linhagens de células cancerígenas humanas. A análise química de W. somnifera mostrou alta porcentagem de saponinas e taninos, enquanto glicosídeos, alcaloides, e flavonoides ocorreram na segunda ordem. Os resultados dos experimentos alelopáticos revelaram uma inibição significativa dos comprimentos de plúmula e radícula de R. dentatus, bem como seus pesos secos relativos. Além disso, foi determinada redução significativa em alguns metabólitos primários de R. dentatus como não redutores e açúcar total, bem como proteínas solúveis. A potencialidade citotóxica de W. somnifera também foi comprovada contra quatro diferentes linhas de câncer, a saber: linha celular de carcinoma hepatocelular humano (HepG2), linha celular de câncer de pulmão de células não pequenas humanas (A549), linha celular de câncer de mama humano (MCF7) e linha celular de câncer de cólon (CaCo2) com valor de IC50 de cerca de 38, 19, 27 e 24 ug/ml, respectivamente.
