使用索氏提取器提取恰玛古籽的油脂,经过甲酯化,气相色谱-质谱法分析其油脂成分.恰玛古籽油脂主要含有顺-13-二十二碳一烯酸(51.64%)、反-9-十八碳一烯酸(18.55%)、反,反-9,12-十八碳二烯酸(10.79%)、顺-11-二十碳一烯酸(9.05%),不饱和脂肪酸占总脂肪酸含量的93.05%,饱和脂肪酸以十六碳酸为主.采用水蒸气蒸馏法对沙枣花中的挥发性成分进行提取,用GC-MS技术对其化学成分进行分离、鉴定,并用峰面积归一法确定各组分的相对含量,共鉴定出21种化合物.含量相对高的有甲基癸二酰氯(55.27%)、反式-肉桂酸乙酯(31.51%)、2,6-二叔丁基对甲苯酚(4.14%)、壬二酸二乙酯(2.01%)、反-9-十八碳一烯酸乙酯(1.69%)、愈创木醇(1.67%).
Analysis for Oil Composition and Volatile Compounds of Two Regional Characteristic Plants in Xinjiang by GC-MS
The oil of Brassica rapa L.seed was extracted by the Soxhlet extraction method.After methyl esterification,the fatty acids in Brassica rapa L.seed oil were analyzed by CG-MS spectrometry.There were erucic acid(51.64%),oleic acid(18.55%),linoleic acid(10.79%),and arachidonic acid(9.05%)in Brassica rapa L.seed,unsaturated fatty acid was 93.05%,and palmitic acid was the main saturated fatty acid.The volatile oil from Elaeagnus angustifolia flower was extracted by steam distillation and analyzed by GC-MS.The peak area normalization method was used for quantification.Totally 21 compounds were identified and accounted for 96.29%of the total volatile oil,mostly including methyl 10-chloro-10-oxodecanoate(55.27%),ethyl trans cinnamate(31.51%),2,6-di-tert-butyl-4-methyl phenol(4.14%),Azelaic acid diethyl ester(2.01%),ethyl oleate(1.69%),and guaiacol(1.67%).
