摘要
Two new coumarins (1–2) have been isolated from a methanol extract of Zanthoxylum schinifolium branches. The structures of compounds 1 and 2 have been elucidated as 6-isopentenyl −7-benzoyl-coumarin and 3-isopentenyl-7-benzoyl-coumarin based on extensive spectroscopic analysis, including IR, NMR, and MS. The inhibitory activity of compounds 1 and 2 against HeLa and HepG2 cell lines has been described.
