HPLC-MSn Analysis of Flavonoids in Epimedium wushanense T. S. Ying
|
Abstract:
This study was aimed to investigate the flavonoids of Epimedium wushanense T. S. Ying using HPLC-MSn. The sample was extracted with 70% ethanol and purified by macroporous resin. The structures were detected by HPLC-MSn experiments. The results showed that twelve compounds were identified from the effective part of Epimedium wushanense T. S. Ying. There are three pairs of isomeric compounds. It was concluded that this method can be used for rapid and accurate identification of flavonoids. It can also be used as reference in the analysis of chemical constituent changes before and after drug processing.
