Objective: To establish a method for the identification and determination of milk Kang tincture. Methods: TLC, TLC and HPLC were used to identify the content of paeonol in Radix Lacton and Radix Aconiti Lateralis Preparata. The content of paeonol in Radix Paeoniae Rubra was determined by high performance liquid chromatography. Results: Cynanchum paniculatum and dragon’s blood can be detected by TLC. Paeonol showed a good linear relationship (r = 0.999 9) with the range of 0.03-0.27 gL-1 and peak area. The average recoveries were 99.01% RSD 2.22% (n = 6). Conclusion: The established method is simple, accurate and reliable and can be used for the quality control of the preparation.
