| Abstract: | Fatty acids in persimmon leaves were extracted with a mixed solvent of ether and n _ hexane, and then the extract was esterfied by NaOH-CH3OH. The esterfied sample was determined by FFAP capillary GC-MS. 21 fatty acids were separated and 19 fatty acids of them were identified, and their relative contents were measured. The main components of the fatty acids in persimmon leaves are myristic acid(6.68%), palmitic acid(30.00%), stearic acid(10.42%),hexadecatrienoic acid(1.44%), linoleic acid(1.84%), 10 _ octadecenoic acid(22.22%),linolenic acid(1.25%),arachidic acid (1.72%), cerotic acid(19.01%). |
