| Abstract: | The article is about the method of using methanol eddy to extract flavonoids from Ginkgo biloba,and the relation between deferent extracting time and content of measured flavonoids from Ginkgo biloba. The measured result can serve as the standard content of flavonoids in Ginkgo biloba if it has been extracted for 8 hours. |
