Abstract:
Objective To study the chemical constituents from the rhizomes of Securidaca inappendiculata. Methods The concrete exacted by 95% EtOH from the rhizomes of S. inappendiculata was isolated and purified by chromatography on macroporous resin, silica gel, MPLC, gel, preparative HPLC, etc. The structures of the chemical constituents were elucidated by means of physicochemical properties and spectroscopic analysis. Results Five compounds were isolated and identified as 2- methylene-butanoic acid 4-O-[(β-D-glucopyranosyl)oxy]-intramol-1,6’-ester (1), 3-methoxyl-4-O-β-D-glucopyranosyloxy-benzoic acid methyl ester (2), threo-4,7,9,9’-tetrahydroxy-3,3’-dimethoxy-8-O-4’-neolignan-4-O-β-D-glucopyranoside (3), eucomegastigside A (4), and acernikol-4″-O-β-D-glucopyranoside (5). Conclusion Compound 1 is a new hemiterpene glycoside named securiterpenoside D, and compounds 2-4 are isolated from Polygalaceae for the first time.
