摘要
用离子色谱法简单快速地分析了中药中的阳离子。分析结果表明,川芎和酸枣仁中5种常见阳离子Na^+,NH^+_4,K^+,Mg^2+和Ca^2+的含量比例不同。各离子的检出限(S/N=3)为0.001~0.013mg/L,线性范围达3个数量级。
A simple and rapid method for the analysis of canons by using ion chromatography was developed.The results showed that the content ratio of Na+, NH4+, K+, Mg2+,Ca2+ in rhizoma chuanxiong and semen zizyphi spinosae are different. The detection limits of canons (S/N=3) were 0. 001~0. 013 mg/L. The calibration curves of peak areas for all analytes were linear over two or three orders of magnitude with a regression coefficient (r2) of 0.999 5~1. 000 0.
