[Studies on chemical constituents from Polygonum macrophyllum].
Zhong Yao Cai. 2004 Jun; 27(6):411-3.ZY

Abstract

OBJECTIVE

To study the chemical structures from Polygonum macrophyllum D. Don.

METHODS

To isolate the constituents by reverse phase chromatography and characterize their structures by the analysis of chemical property and spectral data.

RESULT

Six compounds were isolated from the 70% acetone extract from the complete herb of P. macrophyllum. Their structures were elucidated as (-)-epicatechin-5-O-beta-D-glucopyranoside (I), (+)-catechin-7-O-beta-D-glucopyranoside (II), 1-(3-O-beta-D-glucopyranosyl 4,5-dihydroxy-phenyl)-ethanone (III) (-)-epicatechin (IV), chlorogenic acid (V) and gallic acid (VI).

CONCLUSION

Compounds I-VI were isolated from the plant for the first time.
