【摘要】 目的:建立舒郁胶囊中麻黄碱的鉴别和含量测定方法。方法:采用TLC法和HPLC法对舒郁胶囊中的麻黄碱进行定性鉴别和含量测定。色谱条件:色谱柱为Diamonsil C18柱(250 mm×4.6 mm,5μm),流动相为乙腈-0.02 mol.L-1磷酸二氢钾-磷酸(50∶950∶1),流速1.0 mL.min-1,检测波长207 nm,柱温40℃,进样量10μL。结果:在舒郁胶囊的TLC中检测到麻黄碱的特征斑点,舒郁胶囊中麻黄碱的平均含量为1.133 2 mg.g-1,麻黄碱在5.0~100.0μg.mL-1范围内呈良好线性关系,r=0.999 96,平均回收率为98.96%,RSD=0.23%。结论:本方法简便可行,重现性好,可用于舒郁胶囊中麻黄碱的鉴别和含量测定。 更多还原
【Abstract】 Objective:To establish the method for identification and determination of ephedrine in Shuyu capsule.Methods:Ephedrine in Shuyu capsule was identified by TLC,and the content was determined by HPLC.A Diamonsil C18 column(250 mm×4.6 mm,5 μm) was used with a mobile phase consisting of acetonitrile-0.02 mol·L-1 potassium dihydrogen phosphate-phosphoric acid(50∶950∶1) at a flow rate of 1.0 mL·min-1,the detection wavelength was 207 nm and the column temperature was 40 ℃.The injection volume was 10 μL.... 更多还原
