摘  要:
建立HPLC法测定止咳中药制剂中非法掺入的化学止咳药物克伦特罗。选用Agilent C18(4.6 mm×150 mm,5μm)柱,以甲醇∶0.01 mol/L磷酸二氢钾溶液(磷酸调节pH值为3.5)=25∶75(V/V)为流动相。根据所检测到化合物的色谱保留时间,并与对照品比较,鉴别中药制剂中非法掺入的克伦特罗。结果表明,试验建立的条件能够把中药制剂中添加的止咳化学药物(克伦特罗)完全分离出来;对20种制剂用建立的分析技术进行了检测,经与相应的标准物质比较,得到20种样品均未含克伦特罗。该方法选择性强,灵敏度高,可作为分析检测非法中药制剂的有效手段。

摘  要:
A HPLC method was established for the determination of Clenbuterol mixed illegally in some antitussive Traditional Chinese Medicines.The content of Clenbuterol was determined by HPLC on Agilent C18(4.6 mm×150 mm,5 μm)with methanol-0.01mol/L potassium dihydrogen phosphate(phosphoric acid adjust pH to 3.5)=25∶75(V/V) as a mobile phase.According to the detected compound retention time,compared with the reference substance,the chemical drug Clenbuterol mixed illegally into TCM preparation was identified.The conditions established could entirely separate the Clenbuterol from TCM preparation.Using this method,20 kinds of preparations were detected and compared with the corresponding standard substances,Clenbuterol was undetected in the 20 samples.The method is high selective,sensitive and it could be used as an effective means to detect illegal TCM preparation.
