Abstract

Epimedium brevicornu Maxim (E. brevicornu) is a plant of Epimedium L. in Berberidaceae, which is widely distributed and has high medicinal value and many important clinical applications. In this experiment, a novel flavonoid compound (1) was isolated and identified the chemical structure from E. brevicornu. The extract of E. brevicornu was performed on normal silica column chromatography, ODS silica column chromatography, Sephadex LH-20 column chromatography and RP-HPLC system to be isolated and purified and obtained 1. The HR-ESI-MS and NMR spectrometer were used to measure the accuracy molecular weights and determine the chemical structure of 1. In conclusion, we isolated and purified compound 1 (15.4 mg) and determined its chemical structure.
