摘要

Three new secoprezizaane sesquiterpene lactones, (1R,2S)-1,2- epoxyneomajucin (1), (2R)-2-hydroxyneomajucin (2), and (2R)-2-hydroxymajucin (3), along with six known compounds (4-9), were isolated from the poisonous shrub Illicium micranthum. Their structures were established by in-depth analyses of spectroscopic and mass-spectrometric data.
