摘要：银杏叶经石油醚（６０～９０℃）提取，其软膏的收率为５．１％ ，其中游离脂肪酸的含量为２３．２％ 。该软膏经皂化、中和及萃取等处理，分离得到脂肪酸粗制品，其甲基化衍生物通过ＧＣ－ＭＳ鉴定其化学组成。饱和脂肪酸占２８．５０％ ，由Ｃ１２、Ｃ１４、Ｃ１６、Ｃ１８和Ｃ２０饱和酸组成，主要是Ｃ１６饱和酸（２１．５％ ）；不饱和酸占３３．７％ ，由Ｃ１８∶１、Ｃ１８∶２、Ｃ１８∶３，Ｃ２０∶３和Ｃ２０∶４ 组成，主要是Ｃ１８∶１（９．４％ ）和Ｃ１８∶３（２０．５％ ）；其它部分占３７．８％ ，由炔烃、植醇和饱和脂肪酮等化合物组成。
The paste from Gingko biloba L., using petroleum ether as solvent, has a yield about 5.1% and of which 23.2% are free fatty acids. By soaping, neutralizing and extracting the paste, the raw sample of fatty acids has been seperated. The chemical constituents of the sampl could be identified and analysed by GC MS after methylation. The results show that saturated acids content is 28.5% and consists of C 12 ,C 14 ,C 16 ,C 18 and C 20 acids, mainly C 16 acid (21.5%); unsaturated acids content is 33.7% and consists of C 18∶1 ,C 18∶2 ,C 18∶3 ,C 20∶3 and C 20∶4 acids, mainly C 18∶1 (9.4%) and C 18∶3 (20.50%). The others are about 37.8%, which consist of aliphatic compounds of alkynes, phytols, alkyl acetones and alkyl ethers,etc.
