[Two flavone glycosides from Chinese traditional medicine Amomum villosum].

OBJECTIVE
To study the water soluble constituents from Amomum villosum.


METHOD
The constituents were separated and purified with chromatographic methods, identified by NMR, MS, UV and IR.


RESULT
Two quercetin glycosides: quercitrin (quercetin-3-O-alpha-L-rhamnoside I) and isoquercitrin (quercetin-3-O-beta-D-glucoside II) were isolated and identified.


CONCLUSION
I and II were isolated for the first time from A. villosum.
