摘　　要：目的:研究复方盐酸替利定口服液主要杂质的结构和产生的原因,提高复方替利定口服液的质量。方法:通过LC-MS、IR和H-NMR检测分析其可能的结构并通过分离、合成等方法对杂质结构进行确认,从而在合成工艺上作出相应改进,减少杂质的含量。结果:按照选定方法,获得复方盐酸替利定口服液三个主要杂质(顺式替利定、反式去甲替利定和顺式去甲替利定),并与LC-MS、IR、H-NMR结果一一对应。以此依据在合成工艺方面做出了相应改进,减少了盐酸替利定原料杂质的含量,从而提高了复方替利定口服液的质量。结论:本研究提高了盐酸替利定原料的纯度,进一步对提高复方盐酸替利定口服液的质量具有一定价值。Objective： To analyze the structure and causes of the main impurities so as to improve the quality of compound tilidine hydrochloride oral solution. Methods： The structure of the main impurities was analyzed by LC-MS, IR and H-NMR, then the structure of the impurities was confirmed with separation and synthesis methods so that the synthetic technology was improved to reduce the impurities. Results： By using the selected methods, three main impurities of compound tilidine hydrochloride oral solution（cis-tigridine, trans-nortanilidine and cisformitridine） were obtained in correspondence with the results of LC-MS, IR and H-NMR. Based on the results, the synthetic technology was improved to reduce the impurities of raw material of tilidine hydrochloride and it has improved the quality of compound tilidine hydrochloride oral solution. Conclusion： In this study, the purity of raw material of tilidine hydrochloride was improved, which was valuable in improving the quality of compound tilidine hydrochloride oral solution.
