The polyphenolic composition and antioxidant activity of the aerial parts of 18 medicinal or food plants of the Asteraceae family were studied. Five main caffeoyl derivatives were determined individually by HPLC and compared with levels determined by colorimetry for total dihydroxycinnamic derivatives and total phenolics. The aim of this study was to assess the contribution of these constituent...

Parthenolide, the principal component of sesquiterpene lactones present in medical plants such as feverfew (Tanacetum parthenium), has been reported to have anti-tumor activity. In this study, we evaluated the therapeutic potential of parthenolide against bladder cancer and its mechanism of action. Treatment of bladder cancer cells with parthenolide resulted in a significant decrease in cell vi...

La diabetes mellitus tipo 2 es una afección crónica con elevada prevalencia en las comunidades rurales e indígenas de Guatemala, cuales se ha reportado el uso plantas medicinales para su tratamiento. Con propósito conocer qué son utilizadas la población esta afección, realizó un estudio etnofarmacológico 36 sujetos tz’utujil Santiago Atitlán, Sololá, por medio análisis antropológico y farmacoló...

Parthenolide is a major sesquiterpene lactone derived from feverfew (Tanacetum parthenium) with known anti-inflammatory activity. Moreover, the anticancer potential of this compound was suggested. In this study, we determined the effect of parthenolide on proliferation of three human cancer cell lines: human lung carcinoma (A549), human medulloblastoma (TE671), human colon adenocarcinoma (HT-29...

The in vitro activity of parthenolide against Leishmania amazonensis was investigated. Parthenolide is a sesquiterpene lactone purified from the hydroalcoholic extract of aerial parts of Tanacetum parthenium. This isolated compound was identified through spectral analyses by UV, infrared, (1)H and (13)C nuclear magnetic resonance imaging, DEPT (distortionless enhancement by polarization transfe...
