[Identification of dihydroflavonol glycoside isomers in Smilax glabra by HPLC-MS and HPLC-1H NMR].
OBJECTIVE
To identify dihydroflavonol glycoside isomers in Smilax glabra.


METHODS
The sample was analyzed by HPLC-MS in combination with HPLC-1H-NMR.


RESULTS
Four dihydroflavonol glycoside isomers were identified as astilbin, neoastilbin, isoastilbin, neoisoastilbin.


CONCLUSIONS
The method is simple and rapid for the identification of dihydroflavonol glycosides in S. glabra.
