部分中药材中的砷含量测定及意义
Determination of Arsenic in Part of Chinese Medicinal Herbs and Its Significance
【摘要】 背景与目的:中药中的砷含量及其形态学研究已成为当前中医药领域的研究热点。本文旨在建立科学和可行的砷含量检测方法,并对部分中药中的砷含量进行了测定。方法:中药材样品湿法消化后,采用原子荧光光谱法检测其中的砷含量,并对消化液的种类以及干扰的消除进行了探讨。结果:本法检出限为0.05μg·L-1,样品加标回收率在96.6%~101.6%范围内,相对标准偏差小于2.36%。检测结果显示,大部分中药材中均含有一定量的砷,部分中药材中砷舍量较高。结论:本法灵敏度高,操作简便,重现性好,能够应用于中药材中不同含量砷的分析,具有一定的实用价值。
【Abstract】 Background & Objective:The contents and morphology of arsenic research was a hot spot in the area of Chinese medicinal herbs.This article aimed at establishing a fessoble and scientific method for the determination of arsenic in parts of Chinese medicinal herbs. Methods:The samples were treated by wet digesstion,in which,the contents of arsenic were detected,dicussing the kinds of digestive juice and removal of interference factors.Results:Detection limit of arsenic was 0.05μg·L-1,The recovery rate for the method was 96.6%~101.6% and the relative standard deviation was less than 2.36%.The Results showed that most of Chinese medicinal herbs contained arsenic,part of which had a high arsenic content.Conclusion:This method was sensitive,practical,reproducible and easy to operate,which can be used to an- alyze different contents of arsenic in Chinese medicinal herbs.
