Abstract
(-)-N-Formylanonaine (1), (-)-oliveroline (2), (+)-nornuciferine (3), lysicamine (4), (+)-cyperone (5), (+)-epi-yangambin (6), ficaprenol-10 (7), pheophytin a (8), aristophyll C (9) and michephyll A (10) were isolated from the leaves of Michelia alba DC (Magnoliaceae). Among them, 10 is a new compound. The structures of these compounds were characterised and identified by spectral analyses. We have also presented the antioxidation activity of 10.
