Title: Study on Optimum Extracting Technology of Flavonoids in Ginkgo leaves
Abstract: Ginkgo leaves have been studied a lot recently all over the world.It has been found the flavonoids are the active compounds.Up to now the methods of isolating flavonoids glycosides from Ginkgo leaves are water extraction and organic solvent extraction.Water extraction method is barely used because of low efficiency,high impurity and complexity of post process.In this paper,isolation of flavonoids glycosides is reviewed and ethylalcohol-leaching method is studied.By studying the effect of different temperatures,pHs,phase ratios and leaching times,the optimum conditions were determined.
