Abstract:
With seed coat of Ginkgo biloba as matierials，by the L9 (34) orthiogonal experiment，the Ginkgolic acid was extracted from Ginkgo biloba，the influences of the ratio of solid and liquid，extraction solvent concentration，time and temperature on the extraction effect were investigated.The results showed that the most important factor acid was temperature and the optimum reaction condition was：the ratio of solid and liquid 1∶40，90% methanol concentration，time 2.5 h，temperature 60℃.The best extraction content of Ginkgolic acid at 242 nm，310 nm were 5.946 mg/g and 3.722 mg/g.
