摘　　要：目的研究银杏叶中黄酮的提取工艺,为黄酮的提取分离提供依据。方法分别用乙醇提取法和酶解法提取银杏叶黄酮并对两种方法进行比较。结果银杏黄酮的提取率乙醇提取法为1.29%,酶解法为1.78%。结论酶解法明显优于传统的乙醇提取法。Objective To study the extraction processes of Ginkgo flavone in Folium Ginkgo, Methods Enzymolysis and ethanol extraction were used to extract Ginkgo flavone respectively, Results The extractive rates of Ginkgo flavone was 1.29% for engymolysis and 1, 78% for ethanol extraction respectively. Conclusion Enzymolysis is superior to ethanol extraction.
