Abstract
The flavonoids contents in Ginkgo biloba L were extracted by means of water. The optimum extracting process were determined through orthogonal experiment. The results showed that 100 ℃,20:1 of water to Ginkgo biloba L weight ratio,extracted for 3hours. The flavonoids contents were detected by spectrophotometry,the detected limit is 4mg/mL and the extracted Ginkgo biloba L was added in the persimmon vinegar.
