Abstract: The contents of lipids and flavonoids in different seeds of Ginkgo biloba L. from Taixing were studied.The results showed that:Dongtaiguo contains 7.58% of lipids,Bianfuzi and Dafuzi contain both 4.32% of lipids; Unsaturated oleic acid and linoleic acid were over 65% in fatty acid of lipids.The main composition of lipids were: hexadecenoic acid 2.342%; hexadecanoic acid 7.915%; 7,10-octadecadienoic acid 2.446%;8,11-octadecadienoic acid 31.136%; oleic acid(9,11-C_18:1) 32.873%; stearic acid 1.589%. Dafuzi contains 0.150% of flavonoids; Bianfuzi contains 0.127% of flavonoids. Therefore,there is a nice application foreground in medicine and food development from seeds of Ginkgo biloba L..

Key words: seeds of ginkgo biloba L., flavonoids, lipids, chemical composition of lipids
