摘要
目的:建立Folin比色法测定鹿衔草提取物中总多酚的含量。方法:采用分光光度法测定。以没食子酸为指标,检测波长730 nm。结果:没食子酸在1.08μg/mL^6.48μg/mL范围内线性良好,相关系数为0.9999,加样回收率99.7%,RSD为1.2%(n=9)。结论:本法测定鹿衔草提取物中总多酚的含量,结果准确可行。
Objective:To establish a special determination method of polyphenol ingredient in Pyrola extract. Methods: The content of total polyphenol was detected by chromatometry using gallic acid as index at the wavelength of 730 nm. Results : The lin- ear range of calibration curve was 1.08μg/mL - 6.48 μg/mL for the gallic acid ( r = 0.9999). The average recovery was 99.7% and RSD was 1.2%( n = 9). Conclusion: The method is accurate, can be used in the quality control of Pyrola callitha H.Andres extract.
