| Abstract: | Objective] The research aimed to discuss the optimum conditions for extracting total flavone from the leaves of Ginkgo biloba L.Method] Combined single factor test with orthogonal test,main factors that affected the extraction of flavone were discussed by the method of water extraction.Result] Temperature had the most effect on the extraction of flavone.The extraction rate was highest at 90 ℃,with the ratio of solid to liquid being 1∶60,one hour per time,with 3 repetitions.Conclusion] This research confirmed the optimum method of extracting total flavone from the leaves of G.biloba with water as extracting agent. |
