A phytochemical investigation on the stems and leaves of Clausena lenis led to the isolation of a new furanocoumarin, clauselenisin A (1), together with five known analogues (26). The structure of 1 was elucidated by extensive spectroscopic methods and the known compounds were identified by comparisons with data reported in the literature. All known compounds (26) were isolated from C. lenis for the first time. All isolated compounds were evaluated for their their antiproliferative activities against five human cancer cell lines: HL-60, SMMC-7721, A-549, MCF-7 and SW480 in vitro. Compounds 16 showed significant antiproliferative effects with IC50 values ranging from 0.36 to 16.48 μM.
