摘　　要：对泰兴地区不同品种白果中油脂及总黄酮的含量进行分析。结果表明:东台果中油脂的含量高达7.58%,其次是大佛子和蝙蝠子,两者皆为4.32%。油脂脂肪酸中含有65%以上不饱和油酸和亚油酸,其中棕榈油酸2.342%;棕榈酸7.915%;7,10-C18∶2亚油酸2.446%;8,11-C18∶2亚油酸31.136%;油酸(9,11-C18∶1)32.873%;硬脂酸1.589%。同时筛选出总黄酮含量高的品种,其中大佛子与蝙蝠子总黄酮的含量分别为0.150%、0.127%。因此,白果具有很好的药食开发应用前景。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-C18：1） 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.,
