摘要: | 目的:提高感冒伤风咳茶的质量标准。方法:采用薄层色谱(TLC)法对制剂中防风、甘草进行鉴别;采用高效液相色谱法测定制剂中厚朴酚、和厚朴酚的含量:色谱柱为Phenomenex Luna C18,流动相为甲醇-水(77 ∶ 23,V/V),流速为1.0 ml/min,检测波长为294 nm,柱温为室温,进样量为5 μl。结果:防风、甘草的TLC图斑点清晰,分离度好。厚朴酚、和厚朴酚检测质量浓度线性范围分别为3.13~100.2、3.05~97.6 μg/ml(r=0.999 9);精密度、稳定性、重复性试验的RSD<2%;加样回收率分别为98.2%~99.5%(RSD=0.5%,n=6)、98.6%~99.6%(RSD=0.4%,n=6)。结论:经提高的标准可用于感冒伤风咳茶的质量控制。 |
ABSTRACT: | OBJECTIVE:To improve the quality standard for Ganmao shangfengke tea. METHODS:TLC was used to identify the Saposhnikovia divaricata and Glycyrrhizae Radix et Rhizoma in the preparation. HPLC was used to determine the content of magnolol and honokiol: the column was Phenomenex Luna C18 with mobile phase of methanol-water (77 ∶ 23,V/V) at a flow rate of 1.0 ml/min, detection wavelength was 294 nm, column temperature was room temperature, and the injection volume 5 μl. RESULTS: The TLC spots of S. divaricata and Glycyrrhizae Radix et Rhizoma were clear and well separated. The linear range was 3.13-100.2 μg(r=0.999 9) for magnolol and 3.05-97.6 μg(r=0.999 9) for honokiol; RSDs of precision, stability and accuracy tests were lower than 2%; recoveries were 98.2%-99.5%(RSD=0.5%,n=6) and 98.6%-99.6% (RSD=0.4%,n=6), respectively. CONCLUSIONS:The improved standard can be used for the quality control of Ganmao shangfengke tea. |
