摘要
目的 :测定双黄连注射液中黄芩甙含量。方法 :盐酸溶液沉淀分离采用紫外分光光度法测定双黄连注射液中黄芩甙含量。结果 :平均含量为 6～ 9mg/ml。RSD为 0 .34% ;与HPLC色谱相 ,结果相一致。 结论 :方法简单 ,灵敏度高 ,重现性好 ,结果稳定 ,可作为质量检验的一个快速定量方法。
Objective: To determine the content of baicalin in Shuanghuanglian Injection. Methods: Baicalin was separated from injection by the precipitation separation with chlorhydric acid and determinel by UV spectrophotometry. Results: The average content was 6～9mg/ml, RSD was 0.34%. This result was similar to the results obtained by HPLC. Conclusion: This method is simple, highly sensitive, reproducible with stable results. It can be used as a quickly quantitative method for the quality control of this injection.
