[Chemical constituents of Berchemia lineate].

Objective: To investigate the chemical constituents of the roots of Berchemia lineate as a medicinal plant of Yao nationality in China.

Methods: Compounds were isolated by various column chromatography and elucidated by physicochemical and spectral analysis.

Results: Nine compounds were isolated from the 95% ethanol extract of the roots of Berchemia lineate and their structures were identified as palmitic acid (1), octadecanoic acid (2), beta-sitosterol (3), stigmasterol (4), fernenol (5), chrysophanol (6), physcion (7), floribundiquinone D (8), 2-acetylphyscion(9) respectively.
