Objective To establish the HPLC characteristic map of the reference samples of the classical prescription Zhishi Xiebai Guizhi Decoction (ZXGD, 枳实薤白桂枝汤) and to determine the content of its multi-components, to study the transfer rule of the substance benchmark value of ZXGD, for the follow-up study of Chinese medicine compound preparations lay the foundation. Methods Twenty batches of ZXGD reference samples were prepared, and their characteristic map was established, its characteristic peaks was clarified and assigned to the characteristic peaks; Multi-component content determination on the reference samples of ZXGD was carried out, and the transfer law of main components were analyzed from the decoction pieces to the substance benchmark. Results The similarities of the characteristic maps of the 20 batches of ZXGD reference samples were all greater than 0.93, and a total of 11 characteristic peaks were matched, which were from Zhishi (Aurantii Fructus Immaturus, peaks 1, 3-5, 9), Houpo (Magnoliae Officinalis Cortex, peaks 2, 10, 11), Guizhi (Cinnamomi Ramulus, peaks 6-8); The content range of each index component and the average transfer rate of decoction pieces-reference samples were 0.46%-0.85% and 103.80% for synephrine, respectively, hesperidin 0.58%-1.07% and 42.36%, cinnamic acid 0.025%-0.047% and 105.53%, cinnamaldehyde 0.09%-0.17% and 5.40%, magnolol and honokiol 0.005 6%-0.010 3% and 0.23%. Conclusion The HPLC characteristic map and multi-component content determination are used to study the quantity value transfer law of ZXGD. The whole process quality control of the development and research of classical prescription ZXGD.
