【摘要】 目的:建立麻梗祛痰口服液的质量标准。方法:采用薄层色谱(TLC)法对方中麻黄、桔梗、麦冬进行定性鉴别;采用高效液相色谱法测定黄芩中黄芩苷的含量。结果:TLC中可检出麻黄、桔梗、麦冬。黄芩苷进样量在0.102～1.734μg范围内与峰面积积分值呈良好线性关系(r=0.9996);平均回收率为97.19%,RSD=1.20%(n=6)。结论:所建标准可用于麻梗祛痰口服液的质量控制。更多还原

【Abstract】 OBJECTIVE:To establish the quality standard of Mageng phlegm - eliminating oral liquid.METHODS:Herba Ephedrae,Platycodon grandiflorum and Ophiopogon japonicus in Mageng phlegm - eliminating oral liquid were identified qualitatively by TLC,and the content of baicalin was determined by HPLC.RESULTS:Herba Ephedrae,Platycodon grandiflorum and Ophiopogon japonicus had been successfully detected by TLC.The linear range of baicalin was 0.102～1.734μg (r = 0.9996) with an average recovery of 97.19%(RSD = 1.20%,n = 6).CONCLUSION:The established quality standard is applicable for the quality control of Mageng phlegm -eliminating oral liquid.更多还原
