[Abstract] Objective: To explore the technology in extraction of ginkgolides. Methods: Experiment was designed by orthogonal design, taking the recovery rate of ginkgolides as the observing indexes to investigate the extraction process. Results: The optimal decocting condition was as follow: adding 6-fold acetic ether and ultrasonic extracting three times. Conclusion: The optimal technique used in our investigation can thoroughly extract the ginkgolides from Ginkgo biloba L ......
