Abstract

Microphysiometry was used to evaluate the effects of terpene trilactone and flavonoid constituents of Ginkgo biloba on human platelet-activating-factor receptor (PAFR). Inhibition of the platelet-activating factor response by terpene trilactones was confirmed using this functional assay. Ginkgolide B (GB) and 10-O-benzyl-GB showed the strongest inhibition (81 and 93%, resp.) of the PAFR response, while the flavonoids rutin, quercetin, and kaempferol showed negligible response inhibition. G. biloba extract mixtures were also tested, and results indicate possible synergistic effects among various components.
