Chemical constituents of Selaginella sinensis

Objective To study the chemical constituents from Selaginella sinensis.Methods The compounds were isolated with Diaion HP-20,Toyopearl HW-40,silica gel column chromatography.The structures of these compounds were identified by physicochemical properties and spectral analyses.Results Eleven compounds were isolated from the 70% acetone-extracts and their structures were identified as β-sitosterol(Ⅰ),vanillic acid(Ⅱ),(7S,8R)-4,9,9′-trihydroxy-3,3′-dimethoxy-7,8-dihydrobenzofuran-1′-propylneolignan(Ⅲ),syringaresinol(Ⅳ),(-)-pinoresinol(Ⅴ),pinoresinol-4-Oβ-D-glucopyranoside(Ⅵ),syringaresinol-4,4′-O-di-β-D-glucopyranoside(Ⅶ),β-methylD-xylopyranoside(Ⅷ),β-methyl-D-arabinopyranoside(Ⅸ),hinokiflavone(Ⅹ),and amentoflavone(Ⅺ).Conclusion Compounds Ⅱ-Ⅸ are isolated from this plant for the first time.
