【Abstract】 Object To study the method for separating and purifying the total flavonoids in Hippophae rhamnoides leaves (TFH) with multifunctional resin FL-1. Methods According to structural characteristic of the flavone, FL-1 resin was systematically studied for its adsorption capability. HPLC was used to measure the content of TFH. Results FL-1 resin can be used to produce the TFH with high quality. The purity of the TFH is 40.2% in the dried part of 70% ethanolic elution. Conclusion It is a simple and efficient method to separate the TFH from H. rhamnoides leaves with FL-1 resin.更多还原
