摘要

目的: 研究三七、三七三醇皂苷(PTS)及其制剂三七通舒胶囊中的重金属砷(As)的检测方法及含量。方法: 采用微波消解-氢化物发生-原子荧光法进行测定As

系统地研究微波消解、氢化物发生的最佳条件。结果: 荧光强度与进样浓度之间呈良好的线性关系

线性范围0~12 μg·L-1

回收率为88.37%~104.76%

检出限0.109 6 μg·L-1

RSD为0.82%

PTS及其制剂中As含量较低。结论: 该方法具有简便、快速、灵敏度高等优点

适用于三七、PTS及其制剂中As的测定。

Abstract

Objective: To determine the content of Arsenic(As)in radix notoginseng

panaxatriol saponins(PTS)and Sanqi Tongshu capsule. Method: The content of As was determined by hydride generation atomic fluorescence spectrometry. The optimal experimental conditions of microwave digestion-hydride generation were optimized. Result: Fluorescence intensity and concentration was in a good linear relationship;the linear range was 0-12 ng·mL-1and the recovery was in the range of 88.37%-104.76%

the detection limit was 0.109 6 ng·mL-1

RSD 0.82%;the content of As in PTS and its preparation were low. Conclusion: The method was simple

rapid and high sensitive. It can be used in the determination of As in radix notoginseng

protoparaxotriol saponins and its preparation.
