Identification of Biflavones in Ethyl Acetate Fraction from Ethanol Extract of Selaginella doederleinii Hieron

Abstract:

The chemical constituents were isolated from the ethyl acetate fraction from ethanol extract of Selaginella doederleinii Hieron by column chromatography on silica gel and Sephadex LH-20. The chemical structures of six biflavones were elucidated on the basis of physicochemical properties and spectroscopic data as amentoflavone (1), robustaflavone 7,4',7''-o-trimethyl ether (2), heveaflavone (3), podocarpusflavone A (4), robustaflavone 4',4'''-o-dimethyl ether (5) and robustaflavone 4'-o-methyl ether (6). Biflavones 2, 4 and 5 were obtained from Selaginella doederleinii Hieron for the first time.
