摘　　要：目的:比较不同种千斤拔根、茎、叶及不同产地蔓性千斤拔根中无机元素的含量差异。方法:采用ICP-OES法同时测定千斤拔中25种无机元素的含量,并应用相关性分析、主成分分析和聚类分析法对测定结果进行分析。结果:各种千斤拔所含无机元素的高低顺序不同,差异也较大;各产地的蔓性千斤拔根中无机元素含量总体来看:广西>江西>广东>四川;无机元素间具有显著相关性;通过主成分分析确定V、Co、K、Fe、Cr、P、Mo、Si、Na、Ca、Mg为千斤拔的特征无机元素。通过聚类分析可以较明显地将球穗千斤拔与蔓性千斤拔分开,可将广西、江西、广东、四川等省的千斤拔分别聚类。结论:本试验可为不同种及不同产地千斤拔鉴别和质量评价提供理论依据。Objective： To compare the contents of inorganic elements in root,stem and leaf of several species from Moghania genus and root of M.philippinensis from different habitats.Methods： Inductively Coupled Plasma Optical Emission Spectrum（ICP-OES） was used to determine twenty five inorganic elements simultaneously.The correlation analysis,principal component analysis and cluster analysis were applied for the study of inorganic elements.Results： The content of inorganic elements from different species was difference.As for M.philippinensis from different habitats,the content sequence was GuangxiJiangxiGuangdongSichuan.There was significant correlation between different inorganic elements.The principal component analysis results showed that V,Co,K,Fe,Cr,P,Mo,Si,Na,Ca and Mg might be the characteristic elements of these species from Moghania genus.The results of cluster analysis showed that M.philippinensis and M.strobilifera could be separated and M.philippinensis from Guangxi,Jiangxi,Guangdong and Sichuan could be separated.Conclusion： This experiment provided theoretical basis for distinguish and quality assessment of species from Moghania genus and M.philippinensis from different habitats.
