| Abstract: | OBJECTIVE:To extract and prepare the polyprenols homologues from Ginkgo biloba leaves.METHODS:Petroleum ether as solvent, the lipids including polyprenyl acetates were obtained.By hydrolyzing the lipids, polyprenyl acetates were hydrolyzed into polyprenols.Then polyprenols homologues was obtained by preparative silica gel chromatography.RESULTS:Comparing with the polyprenols standards,polyprenols 16, 17, 18, 19 and 20 can be determinded by HPLC.The purity of polyprenols determined is 76% by external calibration curve of HPLC.CONCLUSION:This extracting process is workable and simple. |
