摘要
目的:对福建、江西、四川等主产地泽泻块茎及其根际土壤中的无机元素含量进行分析,研究其元素分布规律,探讨其关联关系。方法:运用电感耦合等离子体质谱(ICP-MS)进行分析。结果:不同产地泽泻块茎中无机元素的含量呈现有规律的分布特征,均以S、P、K、Mg、Ca含量较高;建泽泻块茎中S、P、K、Fe、Mg、Ca、Al、Zn等元素含量高于江泽泻和川泽泻,有害重金属含量较低;各产地泽泻对P、S、Zn、Mg、Cu元素有富集作用,其中对P、S元素强烈富集;泽泻块茎中无机元素与根际土壤中无机元素呈现一定的相关性。结论:研究工作为对泽泻药效成分生物合成进行人工调控提供了科学依据,同时也为泽泻的道地性成因及品质形成机理研究提供参考。
Objective： To investigate the distribution characteristics and correlation of inorganic element contents in Alismatis Rhizoma and rhizospheric soils from three habitats（Jianou,Fujian;Guangchang,Jiangxi;Pengshan,Sichuan）.Methods：The inorganic element contents were detected with inductively coupled plasma mass spectrometry（ICP-MS）.Results：The results showed that inorganic element contents in Alismatis Rhizoma from different habitats presented regular distribution characteristics.In all samples,the contents of S,P,K,Mg and Ca were relatively high.The contents of S,P,K,Fe,Mg,Ca,Al and Zn in Alismatis Rhizoma from Fujian with low-content harmful heavy metal were more than those of other two places.Alismatis Rhizoma from different habitats showed remarkable ability to enrich P,S,Zn,Mg and Cu,especially to P and S.The contents of inorganic element in Alismatis Rhizoma and rhizosperic soil showed certain correlation.Conclusion：These results provide scientific evidence for artificial modification of effective components biosynthesis in Alisma orientalis,and it could also provide a reference for forming mechanism of genuine characteristics and quality of Alismatis Rhizoma.
