title: Two new ginkgolides from the leaves of Ginkgo biloba.
abstract: Two new diterpenoid compounds, ginkgolide P(1) and ginkgolide Q(2), were isolated from the leaves of Ginkgo biloba L. Their structures were elucidated by various spectroscopic methods, and the structure of 1 was further confirmed by X-ray crystallographic analysis. The activities of the compounds were evaluated against platelet aggregation induced by platelet activating factor (PAF), and the preliminary structure-activity relationship was also discussed.
