CHEMICAL STUDIES ON THE ETHYL ACETATE INS0LUBLE FRAC—TION OF THE ROOTS OF POLYGONUM MUTIFLOUM THUNB

Abstract

Abstract

Two new compounds were isolated from the ethyl acetate insoluble fraction of the roots of Polygonum multiflorum Thunb.The structures of polygonimitin B and C have been established as1,3- dihydroxy-6,7-dimethylxanthone-l-O-β-D-glucoside(Ⅰ) and 2,3,5,4’- tetrahydroxystilbene-2,3-O-β-D glucoside(Ⅱ), respectively,by spectroscopic methods(UV,IR,FAB- MS,¹HNMR,¹³CNM R,¹H-¹³C COSY and NOE different spectrum).
