白木香天然虫漏和人工砍伤所产沉香的GC-MS分析

GC-MS Analysis of the Agarwood Induced by Insects and Chopping

在白木香树自然虫蚀同一树干的相邻部位进行人工砍伤,2年后分别取香,采用气相色谱-质谱(GC-MS)分析,结果表明:这2种方法所产的沉香化学成分相近,但有一定的差异,虫漏沉香的倍半萜和色酮类化合物的相对含量较高。说明沉香的化学成分既受到白木香树的遗传因子的影响,也受到外部作用因子的影响。在本次检测的样品中,虫漏沉香质量为优。

The two adjacent parts of the tree of Aquilaria sinensis had been induced to produce agarwood due to insect infestation and chopping for two years,and the compounds of the argarwood induced were analyzed by using the GC-MS. The GC-MS analysis indicated that the chemical compositions of the agarwood by the two methods were similar,but also had some differences between them. The relative contents of sesquiterpenes and chromones of the agarwood induced by insects were higher than those of the agarwood by chopping. This result shows that the chemical composition of the agarwood is affected by both the genetic factors of the tree and the external factors. In the two agarwood samples tested the quality of the agarwood caused by insects is better than that of the agarwood by chopping.
