1、雷公藤属植物物种间的化学成分差异性研究 [摘要]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
2、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<00001),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。 [关键词]雷公藤属;化学成分;含量测定;主成分分析;偏最小二乘法;方差分析;差异性 Studiesondifferenceofchemicalcompositionsi
