荞麦籽粒石油醚萃取物化学成分的研究

STUDY ON CHEMICAL CONSTITUENTS OF PETROLEUM ETHER EXTRACT FROM THE SEED OF FAGOPYRUM ESCULENTUM

用石油醚抽提荞麦籽粒得荞麦油,然后将油脂用KOH CH3OH水解并甲酯化,以毛细管色谱 质谱联用法测定荞麦油中的组成,分离出50个峰,确认了36种成分,所鉴定的组分占总峰面积的98.11%。其中三十碳六烯、23s 甲基胆甾醇、trans 5,22 二烯 3β 豆甾醇、5 烯 3β 豆甾醇、5,24 二烯,3 豆甾醇、12 烯 3 醇 齐墩果、24 烯,3 醇 9,19 环羊毛甾醇、12 烯 3 醇 熊果醇等未见报道。

Fagopyrum esculentum seed oil was extracted with petroleum ether,then hydrolyzed and esterified with potassium hydroxide and methanol.More than 50 peaks were separated and thirtysix compounds representing 98.11% of the oil were identified by a capillary GCMS. 2,6,10,14,18,22Tetracosahexaene,23smethylcholesterol,transstigmasta5,22dien3β,stigmast5en3ol,stigmast5,24dien3ol,olean12en3ol,9,19cyclolanost24en3ol,urs12en3ol are the compounds that have not been reported in the oil.
