The donkey-hide gelatin (donkey hide glue) is a solid glue made by boiling and concentrating the donkey skin. Due to the scarcity of raw materials, in recent years there have been the use of pigskin glue (New Ejiao), yellow leather glue (yellow gelatin), buffalo skin, miscellaneous leather, bone glue and other counterfeit goods. There have been some reports on the identification of donkey-hide gelatin. In this paper, the identification of donkey-hide gelatin and its counterfeit products was performed by thin-layer chromatography and satisfactory results were obtained. I. Methods and Results 1.
