OBJECTIVE: To identify dihydroflavonol glycoside isomers in Smilax glabra. METHOD: The sample was analyzed by HPLC-MS in combination with HPLC-1H-NMR. RESULT: Four dihydroflavonol glycoside isomers were identified as astilbin, neoastilbin, isoastilbin, neoisoastilbin. CONCLUSION: The method is simple and rapid for the identification of dihydroflavonol glycosides in S. glabra.
