Optimum Extracting Technology of Flavonoid Glycosides in GBE
摘要
Abstract
According to flavonoides' material properity, normal butyl alcohol, npropanol and ethyl acetate are chosen solvent. The optimum extracting conditions of flavonoids from GBE, which the ginkgolide was extracted(ginkgolide contents＜0.3%). The results showed that at 25℃, the ratio of solvents of water to npropanol is equal to 1∶25, the ratio of solid to modified liquid is equal to 15∶1, the extracted time is 10 minutes, the total flavonoides of extraction was more than 50%, the obtained ratio of the total flavonoides in GBE is more than 80%.关键词
