TITLE:
摘要: 目的:建立脉康合剂的质量标准。方法:采用薄层色谱法(TLC)对制剂中白芍、当归、川芎、黄芪、五味子、麦冬进行定性鉴别。采用高效液相色谱法测定制剂中五味子醇甲的含量:色谱柱为Kromasil C18,流动相为甲醇-水(60 ∶ 40,V/V),流速为1.0 ml/min,检测波长为254 nm,柱温为40 ℃,进样量为20 μl。结果:白芍、当归、川芎、黄芪、五味子、麦冬TLC图斑点清晰,分离度好。五味子醇甲检测质量浓度线性范围为1~50 μg/ml(r=0.999 9);精密度、稳定性、重复性试验的RSD<2%;加样回收率为97.01%~98.58%(RSD=0.56%,n=6)。结论:该研究所建标准可用于脉康合剂的质量控制。
ABSTRACT: OBJECTIVE: To establish the quality standard for Maikang mixture. METHODS: TLC was used for the qualitative identification of Paeonia lactiflora, Angelica sinensis, Ligusticum chuanxiong, Astragalus membranaceus, Schisandra chinensis and Ophiopogon japonicus. HPLC was used for the content determination of schisandrin: the column was Kromasil C18 with mobile phase of methanol-water (60 ∶ 40,V/V) at a flow rate of 1.0 ml/min, detection wavelength was 254 nm, column temperature was 40 ℃,and the infection volume was 20 μl. RESULTS: P. lactiflora, A. sinensis, L. chuanxiong, A. membranaceus, S. chinensis and O. japonicus showed clear spots and well separated. The linear range of schisandrin was 1-50 μg/ml (r=0.999 9); RSDs of precision, stability and reproducibility tests were lower than 2%; recovery was 97.01%-98.58% (RSD=0.56%,n=6). CONCLUSIONS: The established standard can be used for the quality control of Maikang mixture.
