Nature and human industrial production process there are some on hepatic toxic substances, can cause varying degrees of necrosis of liver cells, fat deformation, liver cirrhosis and hepatocellular carcinoma. On the treatment of chemical liver injury of many, but for the single drug. The white peony root as main raw materials, using the root of kudzu vine, licorice, Schisandra, Salvia miltiorrhiza as auxiliary material, in the traditional Chinese medicine formula on the basis of the development of health food in strict accordance with the relevant requirements and laws and regulations to adjust, and R&D production against chemical liver injury of health food products, compound white peony liver particles. This article mainly through the orthogonal experiment, the extracting agent concentration, extraction time, extraction temperature, extraction agent, extraction times and other factors pared, and the ultraviolet spectrophotometry, the paeoniflorin, schisandrin, Hone So recovery rate as the main reference index for screening the best extraction process. Experiment results show that the optimal alcohol extraction process of extracting agent:75% ethanol, extracting for three times, extraction time were 1H, solid-liquid ratio are 1:4. Experiment of water extraction process for extracting for three times, each time: liquid ratio1:6, each time are respectively , alc
