摘要(Abstract):

以主成分分析(PCA)和方差分析法(ANOVA)研究雷公藤属植物化学成分的含量与物种相关性,并比较3个物种间的差异。采用[BMIm]PF6离子液体-超声辅助萃取,HPLC法测定28批雷公藤属植物中雷公藤晋碱、雷公藤碱庚、雷酚内酯、雷公藤次碱、雷公藤醌A、雷公藤甲素、雷公藤红素、儿茶素、表儿茶素、表没食子儿茶素和没食子儿茶素11个成分的含量,并进行主成分分析(PCA)、偏最小二乘法(PLS)和方差分析(ANOVA)。结果显示,雷公藤属植物3个物种中11个化学成分的含量测定结果在PCA和PLS分析结果中分别聚集在3个区域,其中雷公藤醌A是影响3个物种分别聚集的最大因素;而且11个化学成分的含量在3个物种间有显著性差异(P<0.000 1),表明化学成分与物种的分类有一定的相关性,3个物种间化学成分含量差异明显。该实验含量测定方法快速准确,分析方法简单方便,为雷公藤属植物的物种分类、药效和毒性研究等提供参考。
We studied the content of chemical compositions and correlation among species of Tripterygium genus by principal component analysis( PCA) and variance analysis( ANOVA),and we also studied the difference among the 3 species. Using [BMIm]PF6ionic liquid-based ultrasonic-assisted extraction,we determined the contents of 11 compounds including wilforgine,wilforzine,triptophenolide,wilforine,triptoquinone A,triptolide,tripterin,egallocatechin,epigallocatechin,catechin,and epicatechin in 28 batches of the Tripterygium species by HPLC and PCA. Partial least squares analysis( PLS) and ANOVA were also performed to verify the results. The analysis results of PCA and PLS showed that three species of Tripterygium genus were clustered into three regions respectively,and triptoquinone A was the important factor which affected the aggregation of these three species. There was a significant difference among the contents of 11 chemical components in the three species( P < 0. 000 1). These results indicated that there was a certain correlation between the chemical compositions and the classification of the species,and the difference of the chemical compositions among the three species was obvious. In this work,the content determination method is rapid and accurate,and the analysis method is simple and convenient,which provides a reference for the classification,the efficacy and the toxicity of the species.
