【 摘 要 】

Two new coumarins namely Clausenalansimin A (5) and B (9) together with seven known coumarins (1-4 and 6-8), were isolated from twigs of Clausena lansium. All compounds were determined by spectroscopic methods. Some of isolates had cytotoxicity against human cancer cell lines (KB, MCF7 and NCI-H187).
