摘要

目的: 建立原子吸收法间接测定芒果苷含量的新方法。方法: 利用碱性环境中

芒果苷可与Sr2+反应生成棕色沉淀的原理

采用原子吸收法间接测定芒果苷含量。以样品溶液中剩余Sr2+为考察指标

考察了温度、时间、pH及沉淀剂用量对反应的影响。在此基础上

进行了方法学考察。结果: 沉淀反应宜在质量浓度为1.395 g·L-1无水氯化锶溶液1 mL

40℃

pH为9.0的条件下反应20 min。该方法线性范围为2.11~59.95 mg·L-1

检出限为0.25 mg·L-1

加样回收率为96.74%

RSD 1.1%。稳定性、精密度和重复性良好。结论: 建立的方法易于操作

线性范围宽

快速省时

可用于测定二母宁嗽丸中芒果苷含量。

Abstract

Objective: To establish an indirect atomic absorption spectrometry method for determination content of mangifer in Ermu Ningsou Wan. Method: Based on the mangifer can be quantitatively generate brown precipitation with Sr2+ in alkaline environment

the content of mangifer in samples was determined indirectly by atomic absorption spectrometry. The effects of temperature

reaction time

pH value and amount of strontium chloride were studied. Result: The conditions of precipitate reaction were chosen as follow:1.00 mL strontium chloride solutions (1.395 g·L-1)

40℃

pH 9.0

and react 20 minutes. Meanwhile

the linear range was 2.11 to 59.95 mg·L-1 and the detection limit was 0.25 mg·L-1. The recovery rate was 96.74%±1.07%. This method performed good stability

precision and repeatability. Conclusion: The proposed method is easy to control and allows the determination of mangifer in a wide range. The results for the analysis are satisfactory.
