[Studies on chemical constituents from Phyllostachys pubescens].
OBJECTIVE
To study the chemical constituents from Phyllostachys pubescens.


METHODS
A extract of P. pubescens was prepared by decocting with boiling water, chromatographed on macroporus resin column and eluted by ethanol. The eluant was separated on silica gel column by eluting with various proportions of chloroform-methanol-water. UV, MS, 1H NMR and 13C NMR were used to elucidate these chemical constituents structure.


RESULTS
Two compounds were isolated as vitexin (I) and orientin (II).


CONCLUSIONS
Two compounds were isolated from this genus for the first time.
