摘要

Bulnesia sarmienti (BS), a traditional South American herbal medicine native to Gran Chaco, has been used to treat various human ailments. The effects of BS aqueous extract (100, 200, and 400 mu g/ml) on H460 cell lines were investigated. High-performance liquid chromatography (HPLC) confirmed that BS contains catechins as major compound. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, cell cycle analysis, DNA fragmentation, apoptosis, and immunoblot analysis on cells were carried out. BS has strong cytotoxic activity on the H460 cell lines (IC(50); less than 100 mu g/ml) in MTT assay. Flow cytometry indicated that BS arrested the cell cycle in the sub-G(1) phase. When BS was treated on H460 cells, DNA fragmentation was increased, and early apoptotic cells were shown to be positive by annexin V staining. Also, the expressions of the p53 and Bax were increased and Bcl-2 protein was downregulated with BS treatment. These results indicated that the BS has anticancer activity on H460 cells and BS may be useful in future therapeutic applications for developing anticancer agents.
