摘    要:目的:建立玫瑰花提取物中鞣质的含量测定方法。方法:以没食子酸为对照品,采用磷钼钨酸一干酪素比色法测定。结果:在2.02~10.08μg·ml^-1范围内吸光度与鞣质含量呈良好的线性关系(r=0.9998),平均回收率为100.14%(RSD=0.69%)。结论:本方法简便、准确,可用于玫瑰花提取物鞣质的含量测定。

关 键 词:玫瑰花  提取物  鞣质  磷钼钨酸-干酪素比色法  含量测定

Abstract:Objective: To establish the method to determine the tannins content in rosa rugosa extracts. Method: The phosphomo- lybdic acid-casein method was used with gallic acid as reference substance. Result: The linear range of tannins was 2. 02-10. 08 μg·ml^-1, and average recovery rate was 100. 14% ,RSD = 0. 69%. Conclusion: The method is reliable and can be used to determine the tannins in rosa rugosa extracts.
Keywords:Rosa rugosa  Extracts  Tannins  Phosphomolybdic acid-casein  Determination
