摘要
目的测定注射用丹参中总钠的含量。方法采用火焰原子吸收光谱法测定注射用丹参中总钠的含量。结果氯化钠在0.5～10mg/L范围内,读数与其浓度呈良好线性关系,平均回收率为101.8%,RSD=1.60%。结论方法简便、快速、准确,可作为本品的质控方法。
Objective To determine the total sodium in Danshen for injection. Methods Flame atomic absorption spectroscopy was used to determine the total sodium in Danshen for injection. Results The calibration curves were linear in the range of 0.5- 10 mg/L for sodium chloride. The average recovery rates of sodium chloride were 101.8%, RSD=1.60%. Conclusion This method was found to be simple, quick and accurate for simultaneous determination of sodium in Danshen for injection.
