【摘要】 目的:建立滴鼻灵的质量标准。方法:采用薄层色谱(TLC)法对方中黄连进行定性鉴别;采用反相高效液相色谱法测定该制剂中盐酸麻黄碱的含量。结果:TLC中斑点清晰、分离度好。盐酸麻黄碱的进样量在0.088～3.520μg范围内与峰面积积分值呈良好线性关系(r=0.996 0);平均回收率为100.82%,RSD=1.19%(n=6)。结论:所建标准可用于滴鼻灵的质量控制。更多还原

【Abstract】 OBJECTIVE:To establish the quality standard of Dibiling.METHODS:Rhizoma Coptidis in the formulation was identified qualitatively by TLC,and the content of ephedrine hydrochloride was determined by RP - HPLC.RESULTS: The TLC spots of Rhizoma Coptidis were clear and distinctive.The linear range of ephedrine hydrochloride was 0.088～3.520μg(r = 0.996 0) with an average recovery rate of 100.82%(RSD = 1.19%,n = 6).CONCLUSION:The established standard is applicable for the quality control of Dibiling.更多还原
