Abstract: Ginkgo biloba polyprenols were used as raw material, three derivatives of Ginkgo biloba polyprenols that included polyprenyl sodium phosphate, polyprenyl acetate and polyprenyl ammonium salt were synthesized by esterification and the structures of the products were characterized. Diameters of inhibition zone to S.aureus and E.coli of Ginkgo biloba polyprenols and their derivatives were determined. The MICs of four samples were determined by coubling dilution and the antibacterial spectra were studied. The results indicated that the four samples displayed good antibacterial activities to S.aureus and E.coli, and the derivatives had stronger antibacterial activity than Ginko biloba polyprenols. Four samples also had antibacterial effect to B.subtilis and S.enterica but had hardly antibacterial effect to A.niger and S.cerevisiae.

Key words: antibacterial, Gingko biloba polyprenols, derivatives
