摘要
目的:研究山西不同产地酸枣仁中脂肪酸类成分的特征。方法:利用气相色谱一质谱联用技术对山西28个不同产地酸枣仁中脂肪酸类成分进行分离与鉴定,采用聚类分析对实验数据进行分析。结果:山西不同产地酸枣仁脂肪酸得率变化范围在22.09%~31.10%;鉴定出共有脂肪酸类成分24种,其中不饱和脂肪酸相对质量分数处于68.22%~89.92%。聚类分析在欧式距离系数5.0处,山西酸枣仁样品明显分为两类。结论:山西产酸枣仁含有丰富的不饱和脂肪酸。产地对酸枣仁中脂肪酸类成分的含量影响较小。深入开发山西产酸枣仁脂肪酸类成分具有较好的区位优势。
Objective:To compare the characteristics of fatty acids in Ziziphi Spinosae Semen (ZSS) from different regions in Shanxi province.Method:Gas chromatography-mass spectrometry (GC-MS)was employed to isolate and identify the fatty acid components in ZSS from 28 growing areas in Shanxi province. Furthermore,hierarchical cluster analysis method was applied to analyze the experimental data.Result:The yield of fatty acids in ZSS from different regions of Shanxi province ranged from 22.09% to 31.10%;a total of 24 fatty acids were identified,the relative amount of unsaturated fatty acids ranged from 68.22% to 89.92%.The hierarchical cluster analysis indicated that all samples in Shanxi province divided into two main types at Euclidean distance coefficient of 5.0.Conclusion:ZSS in Shanxi province is rich in unsaturated fatty acids.The origin has little influence on the content of fatty acid in ZSS.It indicates that Shanxi province has the regional advantages to develop fatty acids in ZSS.
