RESUMEN
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 en-riched extract was separated to give individual terpenes by preparative liquid chromatography. GinkgolideA, B and bilobalide could be isolated with high purity by recrystallizing in MeOH-H2O.
