摘要

A new pyridine, 4-(2′-methylpropoxyl)-2-methylpyridine (14), as well as michelenolide, 11,13-dehydrolanuginolide, parthenolide, santamarine, dihydrosantamarine, (–)-anonaine, oxoxylopine, liriodenine, (–)-N-formylstepharine, scopoletin, coumarin, (3S,4R)-4-hydroxymellein, and (3S,4S)-4-hydroxymellein, were isolated from the stems of Michelia alba. The structure of the new pyridine was elucidated by chemical and physical evidence.
