文摘内容 The purification process of total flavones of ginkgo leaves by resin HZ-841 from ethanol extract was studied. First, the total flavone was extracted from the clef aired powder of ginkgo Lbiloba leaves. Effects of solvents and operation conditions were examined to get a relative high yield and purity in this step. The crude extract was further purified by resin HZ-841. Both adsorption and elution process were studied to obtain an optimized conditions, i.e., pH, flow rate, concentration. A yellow powder was obtained, of which 37.3% was flavones, obviously higher than the basic international standard of 24%。
