【Abstract】 Objective:To develope a method for the separation and preparation ginkgolic acid α 1. Methods: Ginkgolic acids were extracted by alcohol, and adsorbed by silica gel to remove most of the polar impurities. It was preparated with RP HPLC. Results: The extraction ratio of ginkgolic acid α 1 by this extraction process was above 84%, and the purity of ginkgolic acid α 1 reached 98%. Conclusion: This procedure is simple and relatively effective.更多还原
