摘要
目的 :测定二十五味大汤胶囊 (红花 ,诃子 ,毛诃子和余甘子 ,等 )中鞣质的含量。方法 :以没食子酸为对照品 ,采用干酪素法测定鞣质含量。结果 :鞣质含量分别为 0 .96 % ,0 .90 %和 0 .85 %。没食子酸在 0 .8～ 4 .0 μg·mL-1(r =0 .999)范围内呈线性。鞣酸平均加样回收率为 96 .2 % (RSD =1.4 % )。结论 :方法简便 。
Objective: To determine tannins in Ershiwuweidatang Capsules (Flos Carthami, Fructus Chebulae, Fructus Terminaliae Billericae, Fructus Phyllanthi, etc.). Methods:Tannins were determined by casein method.Results: The contents of tannins in Ershiwuweidatang Capsules were 0.96%, 0.90%, and 0.85%, respectively. The gallic acid calibration curves were linear at the ranges of 0.8 ～4.0 μg·mL -1 ( r = 0.999 ). The average recovery of tannic acid was 96.2% with RSD =1.4%( n =5).Conclusion: The method was simple and reliable.
