This study was aimed to establish the thin layer chromatography (TLC) identification and content determination of Tibetan medicineJi-Ni De-Xie (JNDX). TLC was used to identifyBerberis kansuensisSchneid,Terminalia chebula Retz.,Phyllanthus emblicaandCurcuma LongaL. The high performance liquid chromatography (HPLC) was used to determine the content of berberine hydrochloride. The results showed that the TLC identification had a good resolution with clear spots and no interference from the negative reference. The content of berberine hydrochloride showed a good linear relationship with the peak area in the range of 0.05-0.45 mg·mL-1. The regression equation wasY = 40 679X-130.56. The average recovery was 99.07%. It was concluded that the established method was easy to operate with good repeatability. It can effectively control the quality of Tibetan medicine JNDX.
