ICP-OES法测定市售金银花中8种金属元素含量
Determination of the contents of eight metal elements in flowers of Lonicerae Japonicae Flos by ICP-OES
摘要
Abstract
To investigate the contents of 8 metal elements (AI,As,Cd,Cu,Mn,Ni,Zn,Pb) in Lonicerae Japonicae Flos from three main habitats Shandong,Henan and Hebei,microwave digestion was used for treatment of the flower samples,and the contents of 8 elements were determined by ICP-OES.The method showed a good linear relationship (R between 0.999 96～1.000 0),and the average recovery rate between 95.30％～ 101.2％,and the relative standard deviation less than 3％ (n=8),in line with the requirements of the element analysis.Each content of 8 elements (Al、As、Cd、Cu、Mn、Ni、Pb and Zn) in 26 samples of Lonicerae Japonicae Flos was measured,and they were in the ranges of 10.30 ～ 49.68,0.050 0～0.333 3,0.0667～0.333 3,0.300 0～7.317,4.983～26.87,5.767～12.55,0.100 0～ 1.500 and 3.550～16.90 mg/kg respectively.The results showed that the metal element contents in Lonicerae Japonicae Flos were quite different,and some mental contents were too higher or even exceeded the standard values.关键词
