摘要
采用顶空气相色谱-质谱联用(HS-GC-MS)技术对产自5个国家(加里曼丹、马来西亚、孟加拉国、印度、印度尼西亚)的10个沉香样品的挥发性成分进行分析.结果表明,10个沉香样品的挥发性成分主要是芳香族类和倍半萜类化合物,相同产地但形态不同的沉香样品的挥发性组分种类和相对含量均存在一定差异,不同产地沉香样品的挥发性组分也呈现不同的差异,甘香烯、(+)-环苜蓿烯只在马来西亚沉香样品中检出,可作为该产地沉香的特征性成分;α-古芸烯和β-愈创木烯只在印度尼西亚沉香样品中检出,可作为该产地沉香的特征性成分;(+)-α-长叶蒎烯和α-荜澄茄油烯只在印度沉香样品中检出,可作为该产地沉香的特征性成分;产自印度尼西亚的沉香样品中醇类的种类和含量明显低于其他产地.该研究结果为沉香挥发性成分的快速检测和产地鉴别提供了新的思路.
The volatile components of 10 agarwood samples from 5 countries (Kalimantan, Malaysia, Bangladesh, India, Indonesia) were analyzed by headspace gas chromatography-mass spectrometry (HS-GC-MS). The results showed that the volatile components of 10 agarwood samples were mainly aromatic and sesquiterpenoids. The types and relative contents of volatile components of agarwood samples with the same origin but different morphology were different. The volatile components of the samples also showed certain differences. The mannene and (+)-cyclodecene were only detected in the agarwood samples of Malaysia and could be used as the characteristic components of the agarwood in the producing area;α-cluene and β-Guaiacrox were only detected in Indonesian agarwood samples and could be used as the characteristic component of the agarwood in this area;(+)-α-long-leafene and α-carboene were only detected in Indian agarwood samples and could be used as the characteristic component of agarwood in this area;the types and contents of alcohols in agarwood samples from Indonesia were significantly lower than those in other places. The results could provide a new idea for the rapid detection and identification of the agarwood production area.
