摘  要:
采用石油醚抽提荞麦籽,然后将油样进行皂化、甲酯化,以毛细管色谱-质谱联用法测定荞麦籽油中的组分,从分离出的50个峰中确认了23种组分,所鉴定的组分占总峰面积的96.95%。其中脂肪酸中主要成分含量:C18:2≥32.91%,C18:1≥24.73%,C16:0≥20.04%。奇数碳原子脂肪酸、鲨烯、23s-甲基胆甾醇、5-烯-3β-豆甾醇、5,24-二烯,3-豆甾醇、12-烯-3-醇-齐墩果、12-烯-3-醇-熊果等未见报道。

摘  要:
In this paper, Fagopyrum esculentum seed oil was extracted with petroleum ether. Hydrolyzed and esterified withpotassium hydroxide and methanol. After saponification and esterification the oil was determined by capillary GC/MS. Morethan 50 peaks were separated and twenty-three compounds representing 96.95% of the oil were identified. C18:2 & C18:1 &C16:0 were chief components, and their relative contents exceeds 32.91% and 24.73% and 20.04%.There are no reported aboutodd number carbon atomy fatty acid, 2, 6, 10, 14, 18, 22-Tetracosahexaene, 23S-Methylcholesterol, Stigmast-5-en-3-ol, Stigmast-5, 24-dien-3-ol, Olean-12-en-3-ol, Urs-12-en-3-ol.
