Title: Study on Extracting Ginkgo Flavone Glycoside from Leaves of Ginkgo
Abstract: Ginkgo flavone glycoside is extracted from leaves of ginkgo under reflux with water and alcohol. The key factors for extraction process, such as the ratio of feedstock to solvent, alcohol concentration and extraction temperature, are confirmed by orthogonal experiment. The optimum conditions are as follows: the ratio of feedstock to solvent is 1∶10, alcohol concentration is 70%, extraction temperature is 70℃, size of leaves is 40~80 mesh and the extracting time is 2h.The rate of extraction is up to 86.5%.
