Abstract
Three new butanolides, 2-(1-methoxy-11-dodecenyl)-penta-2,4-dien-4-olide (1), (2Z,3S,4S)-2-(11-dodecenylidene)-3-hydroxy-4-methylbutano lide (2) and (2E,3R,4R)-2-(11-dodecenylidene)-3-hydroxy-4-methoxy-4-methylbu tanolide (3), were isolated from the stems of Lindera obtusiloba BLUME. Their chemical structures were assigned by spectroscopic evidence. They exhibited cytotoxicity against cultured human tumor cell lines with their ED50 values ranging from 3.19 to 14.63 microg/ml.Entities:
