文章采用气相色谱-质谱联用技术测定了人工通体结香处理的35个中国沉香样品和51个越南沉香样品的化学成分,并选取了相对含量较高的10种化学成分进行分析。结果表明,10种化学成分的个体间变异都很大,且各种成分相对含量均与沉香树的生长性状呈正相关。此外,越南沉香和中国沉香绝大部分的化学成分相对含量存在显著或极显著差异,中国样品有2种成分含量显著高于越南沉香(P<0.05),越南样品有6种成分含量极显著高于中国样品(P<0.01),显著性的差异可能是由于林木的遗传特性和环境差异造成的。
In this paper, the chemical constituents of 35 Chinese alopecuroides and 51 Chinese alopecuroides samples of Artemisia ordosica were determined by gas chromatography-mass spectrometry (GC-MS), and 10 chemical constituents with higher relative contents were selected for analysis. The results showed that among the ten chemical constituents, the individual variation was very large, and the relative contents of various components were positively correlated with the growth traits of A. fragrans. In addition, the relative contents of most of the chemical constituents in the most of Chinese rosewood and Chinese rosewood were significantly or very significantly different. The contents of two components in Chinese samples were significantly higher than those in Vietnam (P <0.05), and the content of six components in Vietnamese samples was extremely high In Chinese samples (P <0.01), the significant differences may be due to the genetic characteristics of the trees and environmental differences.
