摘 要:目的:用分光光度法测定柏子养心丸中可溶性汞的含量。方法:采用双硫腙比色法在492nm波长下,对3个厂家生产的柏子养心丸进行了测定。结果:河北药都集团(批号:070754、070601和071194)、多邦药业有限公司(批号:22070656)和吉林鹿王制药有限公司(批号:22073064)生产的柏子养心丸中可溶性汞的含量分别为26.39±0.049ug/g、28.31±0.055ug/g、29.14±0.035ug/g、26.42±0.049ug/g和22.45±0.057ug/g。样品的平均加样回收率为97.55%,相对标准偏差(RSD,11=5)为0.58%。结论:本法快速简便,灵敏,精确,适用于中成药中可溶性汞的含量测定及质量检查。Objective: To determine the coment of solubility mercury in Balziyangxin pills by spectrophotometry. Method: Baiziyangxin pills produced in three factories were determined with dithizone colorimetry at the wavelength of 492 nm. Results: The content of solubility mercury in Baiziyangxin pills produced in Hebei Yao Du Group(Lot# : 070754, 070601 and 071194), Duo Bang Pharmaceutical Limited Company (Lot# : 22070656) and Jilin Lu Wang Pharmaceutical Limited Company(Lot# : 22073064 ) was 26.39 ±0.049 ug/g ,28.31±0.055 ug/g ,29.14± 0.035 ug/g , 26.42±0.049 ug/g and 22.45±0.057ug/g respectively.The average recovery was 96.69%, and the relative standard deviation (RSD, n = 5) was 0.45%. Conclusion: The method is rapid, simple, sensitive and accurate, and it is applicable to determine the content of solubility mercury and to check the quality of proprietary Chinese medicines.
