【摘要】 目的:建立测定双参消癃颗粒中哈巴俄苷和二苯乙烯苷含量的方法。方法:采用高效液相色谱法。测定哈巴俄苷含量的色谱柱为Kromasil 100-5 C18,流动相为乙腈-1%醋酸溶液(梯度洗脱),流速为1.0 ml/min,检测波长为278 nm,柱温为25℃,进样量为20μl;测定二苯乙烯苷含量的色谱柱为Kromasil 100-5 C18,流动相为乙腈-水(19∶81,V/V),流速为1.0 ml/min,检测波长为320 nm,柱温为25℃,进样量为10μl。结果:哈巴俄苷、二苯乙烯苷检测进样量线性范围分别为0.555 8~8.893 4μg(r=0.999 9)、0.010 6~0.340 2 mg(r=0.999 6);精密度、稳定性、重复性试验的RSD≤1.80%;加样回收率分别为97.30%~101.35%、96.67%~100.83%,RSD分别为1.43%、1.48%(n=6)。结论:该方法操作简便、结果准确、重复性好,可用于双参消癃颗粒中哈巴俄苷和二苯乙烯苷的含量测定。更多还原

【Abstract】 OBJECTIVE:To establish a method for the contents determination of harpagoside and stilbene glycoside in Shuangshen xiaolong granule. METHODS:HPLC of harpagoside was performed on the column of Kromasil 100-5 C18 with mobile phase of acetonitrile-1% acetic acid solution(gradient elution) at flow rate of 1.0 ml/min,detection wavelength was 278 nm,column temperature was 25 ℃ and volume injection was 20 μ l. HPLC of stilbene glycoside was performed on the column of Kromasil100-5 C18 with mobile phase of acetonitrile-water(19 ∶ 81,V/V)at flow rate of 1.0 ml/min,etection wavelength was 320 nm,column temperature was 25 ℃ and volume injection was 10 μl. RESULTS:The linear range was 0.555 8-8.893 4 μg for harpagoside(r=0.999 9)and 0.010 6-0.340 2 mg for stilbene glycoside(r=0.999 6);RSDs of precision,stability and reproducibility tests were no more than 1.80%;recoveries were 97.30%-101.35%(RSD=1.43%,n=6)and 96.67%-100.83%(RSD=1.48%,n=6),respectively. CONCLUSIONS:The method is simple,accurate and reproducible,and can be used for the contents determination of harpagoside and stilbene glycoside in Shuangshen xiaolong granule.更多还原
