摘　　要：以石油醚为溶剂提取曼陀罗种子中的脂肪酸,采用GC-MS技术测定其化学成分,并通过饲料混毒法测定了曼陀罗种子脂肪酸对小鼠的毒性.结果表明,曼陀罗种子中含有23.2%的脂肪酸,其主要化学成分为1,20-二十碳二酸(34.55%)、Crinan-3-ol,1,2-didehydro-,(3à)(13.41%)、8,11-十八碳二烯酸(4.56%)、8,11,14-二十碳三烯酸(Z,Z,Z)(4.39%)、2,3,3-三甲基辛烷(4.35%)、7,10-十八碳二烯酸(3.61%)、亚油酸乙脂(2.64%)、α-亚麻酸(2.34%)、cis-乙酸环己脂-2-丙酸(2.34%)等.采用饲料混毒法对小鼠的毒性测定结果表明,曼陀罗种子脂肪油对小鼠无胃毒作用.研究认为,曼陀罗种子中含有多种对人体有益的活性成分,可作为脂肪酸食用油来源或从中提取对人体有益的活性成分开发利用.The paper reported the content of the seed oils from Datura stramonium L.,its fatty acid components and toxicity to mice.The fatty acid were extracted by petroleum ether and its chemical components were identified by GC-MS,and determined by GC.It is shown that the fat acids are mainly composed of 1,20-Eicosanebioic acid（34.55%）,Crinan-3-ol,1,2-didehydro-,（3à）（13.41%）,8,11-Octadecadienoic acid（4.56%）,8,11,14-Eicosatrienoic acid（Z,Z,Z）（4.39%）,Octane,2,3,3-trimethyl-（4.35%）,7,10-Octadecadienoic acid（3.61%）,linoleic acid ethyl ester（2.64%）,α-octadecatrienoic acid（2.34%） and Cyclohexanepropanoic acid,2-（acetyloxy）-,methyl ester,cis-et al.Toxicity of the seed oils from Datura stramonium L.to mouse was bioassaied by sample incorporated in the diet.The results indicated that the fat oils without toxic effects of the stomach on mouse.The seed of Datura stramonium L.contain a variety of active composition which is beneficial for human body.It is very worth to develop and utilize as a source of edible oil or extract active composition.
