Abstract: OBJECTIVE The optimal extraction process and inclusion process of volatile oil in Xianglian Hewei soup were selected to improve the utilization rate of volatile oil. METHODS The index was based on the content of the main ingredients patchouli alcohol, cineole, bomyl acetate and the yield of volatile oil, the GC method was used to determine the content of active ingredients, the DX8trial designed the test plan, and the entropy weight method was used to process the experimental data, and finally screened out the best extraction process for volatile oil. Used grinding method to clathrate volatile oil, and the inclusion scheme was designed through orthogonal experiments, and record 3 indicators of volatile oil inclusion rate, inclusion compound yield and inclusion compound oil rate one by one. The entropy weight method was used to perform the index Weight analysis, calculate the comprehensive score of the three indicators according to the weight coefficient, and screen out the best inclusion technology. RESULTS The best extraction process for volatile oil was immersion time of 1.5 h, extraction time of 8 h, and the amount of water added of 8 times water. The best inclusion process was as follows:prepared by grinding method, β-CD-volatile oil was 6︰ 1, material liquid ratio was 6︰ 1 and the grinding time was 0.5 h. CONCLUSION The best extraction process of volatile oil selected by the experiment can increase the yield of volatile oil and the content of active ingredients in Xianglian Hewei soup, and the best inclusion technology obtained by screening can effectively include the volatile oil in Xianglian Hewei soup.
