New sesqui-neolignan from the pericarps of Illicium macranthum.

Abstract

A new triphenyl lignan, macranthol, was isolated from the pericarps of Illicium macranthum (Illiciaceae), a Chinese Illicium plant. The structure was deduced to be a trimer of C6-C3 units by the extensive application of two dimensional nuclear magnetic resonance spectroscopy, and by comparison with the structures of neolignan, honokiol and magnolol, which were isolated from Magnoliaceae Plants.
