摘要

To study the chemical constituents of the root tube from Pteroxygonum giraldii.Column chromatography and spectral analysis were used to isolate and identify the constituents.Ten compounds were isolated and identified as beta-sitosterol (I), beta-sitosterol glucoside (II), 4', 5,5', 7-tetrahydroxy-3'-methoxy-3'-O-alpha-L-arabinopyranosyl flavone (III), gallic acid (IV), myricetin (V), annulatin (VI), 5,5', 7-trihydroxy-2',3-dimethoxy-4'-O-beta-D-glucopyranosyl flavone (VII), 2', 5,5',7-tetrahydroxy -3-methoxy-4'-O-beta-D-glucopyranoside flavone (VIII), myricetin-3-O-alpha-L-rhamnopyranoside (IX) and myricetin-3,4'-dimethyl ether( X).Compounds I, II, V, VIII and X are isolated from Pteroxygonum giraldii for the first time.
