摘要: 目的:建立HPLC法同时测定桂灵片中6种生物碱的含量。方法:采用Agilent Eclipse Plus-C18色谱柱(4.6 mm×250 mm,4.6 μm),以乙腈(A)-0.1%磷酸(B)为流动相,梯度洗脱,流速1.0 mL·min-1,测定波长:吗啡、盐酸麻黄碱、盐酸伪麻黄碱、盐酸甲基麻黄碱、磷酸可待因210 nm;盐酸罂粟碱251 nm。结果:吗啡、盐酸麻黄碱、盐酸伪麻黄碱、盐酸甲基麻黄碱、磷酸可待因和盐酸罂粟碱进样量分别在0.001 3~0.13 μg(r=0.999 9),0.002 5~0.25 μg(r=0.999 9),0.002 5~0.25 μg(r=0.999 9),0.005 4~0.27 μg(r=0.999 9),0.002 6~0.26 μg(r=0.999 9),0.000 5~0.11 μg(r=0.999 9)范围内呈良好线性关系,平均回收率(n=6)分别为101.6%、100.2%、95.3%、99.2%、103.5%、100.2%。结论:该方法可以用于桂灵片的质量控制。

Abstract: Objective:To establish an HPLC method for simultaneous determination of six alkaloids in Guiling tablets,and to analyze the results by principal component analysis. Methods: Separation was performed on a Agilent Eclipse Plus-C18 column(4.6 mm×250 mm,5 μm).And the mobile phase consisted of acetonitrile(A)and 0.1% phosphoric acid(B)with gradient elution at a flow rate of 1.0mL·min-1.The detection wavelength was 210 nm for morphine、ephedrine、pseudoephedrine、methylephedrine hydrochloride、codeine and 251 nm for papaverine. Results:Morphine、ephedrine、pseudoephedrine、methylephedrine hydrochloride、codeine and papaverine showed good linearity in the ranges of 0.001 3~0.13 μg(r=0.999 9), 0.002 5~0.25 μg(r=0.999 9), 0.002 5~0.25 μg(r=0.999 9), 0.005 4~0.27 μg(r=0.999 9), 0.002 6~0.26 μg(r=0.999 9), 0.000 5~0.11 μg(r=0.999 9).The average recoveries(n=6) were 101.6%、 100.2%、95.3%、99.2%、103.5%、100.2%. Principal component analysis extracted two principal components,and explained 91.7% of the group differences, which better reflected the difference between groups. Conclusion:The method is applicable for the quality control of Guiling tablets.
