[Studies on chemical constitutents from Penthorum chinense Pursh].
OBJECTIVE
To study the chemical constituents of Penthorum chinense.


METHODS
Silica gel and macroporous resin were used as adsorbent for isolation and purification. The chemical structures were elucidated by spectral analysis and chemical methods.


RESULTS
Three compounds were isolated from the water-extract of P. chinense. The structures were identified as 5-hydroxy-flavanone-7-O-beta-D-glucoside (I), 2,4,6-trihydroxybenzoic acid (II) and quercetin(III), respectively.


CONCLUSIONS
Compounds I and II were isolated from this plant for the first time.
