Abstract
The effects of Bulnesia sarmienti (BS) aqueous extract on the cell growth of A549 cell lines were investigated. BS has strong cytotoxic activity on the A549 cell lines (IC50; less than 100μg/mL) in MTT assay. HPLC confirmed that BS contains catechins as major compound. Cell cycle analysis by flow cytometry indicated that BS arrested the cell cycle in the sub-G1 phase. BS induced DNA fragmentation, and increased the expression of the p53 protein in immunoblot analysis. These results indicated that the anticancer effect of BS was mediated via the process of apoptosis and growth-inhibition.
