【摘要】 [Objective] To prepare highly purified flavonoids of Ginkgo biloba L., so as to explore a large-scale preparation process route for high purity flavonoids from Ginkgo biloba L.. [Method] Purified with chromatographic column with packing of ODS, effects of mobile phase ratio, concentration temperature and drying temperature on yield of flavonoids from Ginkgo biloba L. were investigated. [Result] The optimum preparation conditions were as follows: target fraction of methanol to 0.5% phosphoric acid ratio of 5∶5 and 7∶ 3, concentration temperature and drying temperature of 45 ℃. The content of flavonoids from Ginkgo biloba L. was more than 90%, and the yield was up to 78.3% under the optimal preparation process. [Conclusion] High-purity flavonoids from Ginkgo biloba L. are obtained, which provides an effective means for the preparation of highly purified Ginkgo biloba L. flavonoids.
