摘要(Abstract):

目的:鉴定土茯苓中的二氢黄酮醇苷异构体。方法:采用高效液相色谱-质谱法(HPLC-MS)与高效液相色谱-核磁共振氢谱法(HPLC1-H-NMR)对土茯苓提取液中的二氢黄酮醇苷类成分进行分析鉴定。结果:从土茯苓中鉴定出4个二氢黄酮醇苷异构体,分别为落新妇苷、新落新妇苷、异落新妇苷和新异落新妇苷。结论:该法能简单、快速地鉴别土茯苓中的二氢黄酮醇苷类成分。
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.
