Ten phenolic compounds were isolated from the CHCl3 extract of Ginkgo biloba sarcotestas (Ginkgoaceae) as a new class of phosphatidylinositol-specific phospholipase C gamma 1 (PI-PLC gamma 1) inhibitors. The substances without the long chain were ineffective. On the other hand, the activities of these compounds were dramatically decreased by acetylation of aromatic hydroxyl groups of cardanol, phenolic acid, and bilobol and by methylation of the aromatic carboxyl group of phenolic acid. The unsaturated long chain as well as the aromatic hydroxyl and carboxyl groups might play a key role for the PI-PLC gamma 1 inhibitory activity. These compounds also inhibited the growth of a number of human cancer cell lines, but were less cytotoxic against a human normal colon cell line.

A monophosphate derivative of ginkgolic acid binds to sphingosine 1-phosphate (S1P) receptors to perform similar functions to the lipid mediator S1P.
Seven long-chain phenols were isolated from Ginkgo biloba L. Three of them, anacardic acid (Ib), bilobol (IIa), and cardanol (IIIa), showed antitumor activity against Sarcoma 180 ascites in mice. The antitumor effectiveness was rated (+ +) for Ib, (+ + +) for IIa, and (+ + +) for IIIa at 40 mg/kg/d by the total packed cell volume method.
