Traditional Chinese medicine( TCM) glues,including leather glues,horn glues,nail glues and bone glues,have a long application history and unique characteristics. In recent years,their market demand has increased year by year because of their remarkable curative efficacy and nourishing effects,which leads to insufficient supply of raw material resources,and widespread use of fake and inferior products,seriously affecting the reputation of TCM glues and drug safety. In this context,the establishment of a more specific quality detection method for the TCM glues according to their specific characteristics can effectively improve the quality control level,promote rational use,and have a far-reaching impact on the industrial development of TCM glues. In this paper,the classification of TCM glues,as well as the production and application status of their representative( Ejiao) were briefly introduced; the papers on quality control technologies of TCM glues,including traditional identification experience,authenticity identification,physical property determination,protein,peptide and amino acid contents determination,element analysis,biological evaluation,and brand protection technology of TCM glues,were reviewed,and their advantages and disadvantages were summarized and analyzed comprehensively.Based on the specific characteristics of TCM glues,such as complex material basis,unclear pharmacodynamic components and different production processes,it was proposed in this paper to research and develop information-rich,convenient,fast,and non-destructive analytical techniques for the quality control of TCM glues and brand protection of famous products,thus promoting the healthy development of TCM glues industry.
