Ginkgolic acid inhibits fusion of enveloped viruses Abstract Ginkgolic acids (GA) are alkylphenol constituents of the leaves and fruits of Ginkgo biloba. GA has shown pleiotropic effects in vitro, including: antitumor effects through inhibition of lipogenesis; decreased expression of invasion associated proteins through AMPK activation; and potential rescue of amyloid-β (Aβ) induced synaptic impairment. GA was also reported to have activity against Escherichia coli a
