摘要: 建立川麦冬无机元素含量测定的电感耦合等离子体原子发射光谱(ICP-OES)分析方法,并对川麦冬无机元素含量进行分析与系统评价。通过湿法消煮,用ICP-OES方法测定川麦冬无机元素含量,并用SPSS 21.0软件对数据进行相关性分析和主成分分析。结果表明川麦冬药材中Ca、P、K、Mg、Fe、Al元素的含量较高,Co、Hg、Se、Si、Sn、V在麦冬中未检测到或低于检测限,3个样品采集点的麦冬药材Cd元素含量超过WM/T2-2004 Cd(≤0.5 mg/kg)的限量标准;无机元素之间有一定的相关性;主成分分析表明As、Ba、Cu、K、Mg、Mn、P、Sr、Ti是川麦冬的特征无机元素。本研究可为川麦冬质量控制和安全性评价及临床药用提供科学的参考依据。

Abstract: The aim of this study was to establish a method for simultaneous analysis of inorganic elements in Ophiopogon japonicus by inductively coupled plasma optical emission spectromter (ICP-OES),and to evaluate the different batches.The sample solutions were analyzed by ICP-OES after wet digestion.The data of correlations and principal components were analyzed with the SPSS 21.0 software.The results showed that the contents of Ca,P,K,Mg,Fe and Al were abundant,while the contents of Co,Hg,Se,Si,Sn and V were not detected or below the detection limit in O.japonicus.But it was important to emphasize that the content of Cd was above the Standard of WM/T2-2004 in three samples.And there were some correlations among the inorganic elements in O.japonicus.The PCA analysis results showed that As,Ba,Cu,K,Mg,Mn,P,Sr and Ti may be the characteristic elements in O.japonicus.This study provided the evidence for the quality control and safety evaluation of O.japonicus.

Key words: Ophiopogon japonicus, inorganic elements, inductively coupled plasma optical emission spectromter, principal component analysis
