【摘要】：为比较不同产地依兰依兰油成分差异,采用气相色谱-质谱法(GC/MS)对马来西亚、中国广东、云南三个产地的依兰油进行挥发性成分分析,并通过质谱库检索,结合保留指数验证,从三种依兰依兰油中依次鉴定出83、61和34种挥发性成分,分别占总峰面积的89.28%、92.41%和95.74%,三种依兰依兰油的挥发性成分在数量及含量上有一定的差异。结合主成分分析(PCA)对三个产地依兰依兰油中致香物质的差异进行了分析,结果显示造成马来西亚依兰依兰油差异的主要成分为苯甲醇、水杨酸苄酯、α-蛇麻烯、(E,E)-α-金合欢烯、δ-杜松烯等,造成云南依兰依兰油差异的主要成分为(E)-异丁香酚乙酸酯、乙酸肉桂酯、(E,E)-金合欢醇乙酸酯、芳樟醇、对甲酚甲醚、乙酸香叶酯等,造成广东依兰依兰油差异的主要成分为(Z,E)-金合欢醇、β-石竹烯等。该研究为依兰依兰油的合理开发利用提供初步实验依据。
[Abstract]:In order to compare the composition differences of Yilan oil from different habitats, the volatile components of Yilan oil from Malaysia, Guangdong and Yunnan were analyzed by gas chromatography-mass spectrometry (GC/MS). From the three kinds of Yilan oil, 83O61 and 34 volatile components were identified in turn, accounting for 89.28% and 95.74% of the total peak area, respectively. The volatile components of the three kinds of Yilan oil were different in quantity and content. The difference of aromatic substances in Yilan oil from three producing areas was analyzed by principal component analysis (PCA). The results showed that benzyl alcohol was the main component causing the difference in Yilan oil from Malaysia. Benzyl salicylate, 伪 -ophiphene, (Elaucene)-伪 -asparagene, 未 -dusonene and so on. The main components causing the difference of Yilan oil in Yunnan are (E) isoeugenol acetate, cinnamyl acetate, (Ele) -acacinol acetate, linalool, p-cresol methyl ether, vanillin acetate, etc. The main components that caused the difference of Yilan oil in Guangdong province were (Zhe E)-acacinol, 尾-caryophyllene and so on. This study provides a preliminary experimental basis for the rational exploitation and utilization of Yilan oil.
