| Abstract: | A simple method for the isolation and purification of ginkgolide A, B and bilobalide (ginkgo terpene trialctone) was developed A commercially available extract of leaves of Ginkgo biloba L. containing >6% ginkgo terpene trilactone was used as the raw material After partition in EtOAc, the enriched extract was separated to give individual terpenes by preparative liquid chromatography Ginkgolide A, B and bilobalide could be isolated with high purity by recrystallizing in MeOH H 2O |
