The advantages and applications of NMR in the analysis and identification of pharmaceutical materials were discussed,based on paper investigation and our own experience.The real cases showed that NMR could play an unique role in the pharmaceutical assay due to its distinctive technical characteristics,such as multi-methods available,plenty of information provided and flexibility of qNMR.In these cases,the main components in each of mixtures were identified and their contents（or relative cintens） were determined simultaneously by NMR techniques within a relatively short time.
