摘要/Abstract

摘要：

建立了ICP-AES/ICP-MS测定西藏和河南产藏红花中19种元素含量的方法。19种元素包括主要元素Ca、Fe、Mg、P、Sr、Al、Mn、Zn、V、Cr、Se、Co、Ni、Mo和重金属As、Cu、Cd、Hg、Pb。对于所测元素, 标准曲线的相关系数>0.9938, 方法的相对标准偏差RSD<5.25%。结果表明, ICP-AES/ICP-MS可用于藏红花质量控制, 并为西藏和河南产藏红花中元素的含量测定提供了方法。

Abstract:

A quick and sensitive method was developed for the determination of 19 metal elements in Saffron, a traditional Chinese medicinal herb, collected from Tibet Autonomous Region and Henan Province of China using inductively coupled plasma atomic emission spectrometry (ICP-AES) or inductively coupled plasma mass spectrometry (ICP-MS). The determined 19 metals in Saffron include Ca, Fe, Mg, P, Sr, Al, Mn, Zn, V, Cr, Se, Co, Ni, Mo, and heavy metals As, Cu, Cd, Hg and Pb. For all the analyzed elements, the correlative coefficients of the calibration curves were no less than 0.9938. This proposed method was accurate, and the relative standard deviations of the measurements were lower than 5.25%. It can be used for the quality control of metal elements in Saffron.
