Method for detecting herba ephedrae, fried semen armeniacae amarum, radix glycyrrhizae and radix scutellariae in Antiasthmatic Oral Liquid for Child

The invention relates to the technical filed of drug detection, in particular to a method for detecting herba ephedrae, fried semen armeniacae amarum, radix glycyrrhizae and radix scutellariae in Antiasthmatic Oral Liquid for Child. A to-be-detected object is detected by a high-performance liquid chromatograph, and a chromatogram is obtained and analyzed. Accurate and qualitative identification ofthe four medicinal materials and sodium benzoate is realized by screening chromatographic peaks corresponding to the herba ephedrae, the fried semen armeniacae amarum, the radix glycyrrhizae, the radix scutellariae and sodium benzoate in the Antiasthmatic Oral Liquid for Child; the method is environmentally friendly, efficient and good in reproducibility and can be used for qualitative quality control of the Antiasthmatic Oral Liquid for Child. 本发明涉及药品检测技术领域，特别涉及种同时鉴别小儿定喘口服液中麻黄、炒苦杏仁、黄芩和甘草的检测方法。对待检物进行高效液相色谱仪检测得到色谱图，对色谱图进行分析。通过对小儿定喘口服液中存在与麻黄、炒苦杏仁、黄芩和甘草及苯甲酸钠相应的色谱峰进行筛选，实现了上述四味药材及苯甲酸钠的准确定性鉴别；该方法环保、高效，重现性好，可用于小儿定喘口服液的定性质量控
