| 摘 要： | In this paper a simple preparative method for isolation and purification of ginkgolides A and B was developed,As starting material,a commercially available standardized ginkgo extract (EGb761,containing 24% flavonoid and 6% terpene trilactones) was used,After a pretreatment step,optimized by the uniform design method ,the concentrated intermediate extract with high content of GA and gb( 90%) was separated into the individual terpenes by preparative liquid chromatography eluted with petroleum ether-ethylacetate,Analysis of products was carried out by means of HPLC-ELSD(evaporative light -scattering detector),The results show that ginkgolides A and B are obtained in higher yield and better purity.

| Abstract: | In this paper, a simple preparative method for isolation and purification of ginkgolides A and B was developed. As starting material, a commercially available standardized ginkgo extract (EGb761, containing 24% flavonoid and 6% terpene trilactones) was used. After a pretreatment step, optimized by the uniform design method, the concentrated intermediate extract with high content of GA and GB (+90%) was separated into the individual terpenes by preparative liquid chromatography eluted with petroleum ether-ethylacetate. Analysis of products was carried out by means of HPLC-ELSD (evaporative light-scattering detector). The results show that ginkgolides A and B are obtained in higher yield and better purity. |
