Chemical constituents from Curculigo orchioids / 中成药

ABSTRACT

AIM To study the chemical constituents from Curculigo orchioides Gaertn..METHODS The n-butanol fraction of 95％ ethanol extract from C.orchioides was isolated and purified by silica,macroporous resin and Sephadex LH-20,then the structures of obtained compounds were identified by spectral data.RESULTS Seven compounds were isolated and identified as anacardoside (1),ocinol glucoside (2),3-(4-hydroxyl-3-methoxyphenyl)-propan-1,2-diol (3),benzyl-O-β3-D-glucopyranoside (4),icariside F2 (5),glucosyringic acid (6),calleryanin (7).CONCLUSION Compounds 3-7 are isolated from genus Curculigo for the first time.
