Chemical constituents of Lepidozia vitrea / 中草药

Objective To study the chemical constituents from alcohol extract and water extract in Lepidozia vitrea in order to find out their bioactive compounds.Methods The chemical constituents were isolated by various column chromatographic methods and the structures of the compounds were elucidated by spectral analysis.Results Six compounds were obtained and their structures were identified as phytol (Ⅰ),7-hydroxycalamenene(Ⅱ),daphnetin(Ⅲ),and daucosterol(Ⅳ) from the alcohol extract,D-glycero-D-galacto-heptitol(Ⅴ) and D-erythro-L-galacto-octitol(Ⅵ) from the water extract.Conclusion Compounds Ⅰ-Ⅵ are isolated from this plant for the first time.
