摘要
采用气相色谱-质谱(GC-MS)结合化学计量学方法,分析檀香木心材的可挥发性化学成分。结果显示,檀香木心材精油与石油醚提取物的总离子流图基本一致,且挥发性成分相同,表明石油醚提取物能够表征檀香木心材中挥发性成分的化学特征;四个产地的檀香石油醚提取物的化学成分含量存在差异,以α-檀香醇和β-檀香醇等5个主要成分的含量建立判别模型,可用于檀香产地识别。
Gas Chromatography-Mass Spectrometer(GC-MS)combined with chemometrics methods were used to analyze volatile components in Santalum album Heartwood.The results showed that GC-MS chromatographs of petroleum ether extracts were similar to those of the essential oils distilled from Santalum album heartwood,which meant that the petroleum ether extracts could profile volatile components in Santalum album heartwood.The volatile components profiles of Santalum album from 4 habitats were similar in components but different in concentrations.A discriminate analysis(DA)model based on the percentiles of α-santalol,β-santalene,Z-α-trans-bergamotol,epi-β– santalol andβ-santalol was proposed to identify Indian Santalum album.
