摘要:

为了探索消癌平注射液中的重要化学成分及质量控制新方法,该文运用1H NMR,13C NMR,DEPT,1H-1H COSY,HSQC及HMBC技术,在消癌平注射液复杂化学成分体系中鉴别出牛奶菜醇,并以对苯二酚为定量内标,NMR内标法测定消癌平注射液中牛奶菜醇的绝对含量. 以化学位移分别在δ 5.73,δ 6.73处的牛奶菜醇和对苯二酚的质子峰为定量特征峰,其峰面积比(Ax/Asy)与注射液冻干粉与对苯二酚的质量比(Wx/Wsx)的线性回归方程为y=0.034 1 x+0.090 6,相关系数为0.999 6,精密度实验RSD为1.27%,重复性实验RSD为2.16%,稳定性实验RSD为0.13%. 分析结果表明:该方法快速、准确、简便,为消癌平注射液的质量控制及质量标准的完善提供了新的方法.

Abstract:

In order to establish a quality control method for Xiaoaiping Injection, one-dimensional and two-dimensional NMR techniques used to measure the important chemical constituents, including condiritul, in the injection. An NMR method for quantitative analysis of condiritul using hydroquinone as the internal standard was presented. The proton signals of condiritul at δ 5.73 and those of hydroquinone at δ 6.73 were used for quantification. Linear regression of quantitative peak area ratio (Ax/As, y) of condiritul-hydroquinone versus mass ratio (Wx/Ws, x) yielded a regression equation of y=0.034 1 x+0.090 6 with a correlation coefficient of 0.999 6. The precision relative standard deviation (RSD) was 1.27%, the reproducibility RSD 2.16% and the stability RSD 0.13%. The results showed that 1H NMR can be used for quantitative measurement of condiritul in Xiaoaiping Injection.
