摘要
目的 建立测定益肝口服液中人参总皂苷含量的方法。方法 采用大孔吸附树脂分离 -比色法。结果 人参皂苷Rg1在 30 4～ 182 4 μg范围内呈良好的线性关系 (r=0 9997) ,平均回收率为 98 0 2 % ,方法精密度RSD =1 4 7% (n =5 ) ,3批样品平均每支含量为 11 5 5 0mg。结论 本方法简便、灵敏、准确、重复性好 ,可用作该制剂的质量控制。
OBJECTIVE To determine the ginsenosides contents in Yigan oral solution. METHODS A macroreticular resin-colorimetric method was applied. RESULTS A good linearity was found in the concentration range of 30.4-182.4 μg for ginsenoside Rg1(r=0.9997), and the average recovery was 98.02% with RSD of 1.47%(n=5). The average content of the ginsenosides in Yigan oral solution was 11.55 mg per bottle. CONCLUSION This method was simple,sensitive,accurate and reproducible, the macroreticular resin-colorimetric method to be adopted in this paper could be used for quality control in the production of Yigan oral solution.
