Résumé
Objective:To screen the optimal process of ambi-extracting of Xinyi Powder and inclusion of volatile oil.Methods:Single factor experiment was used to optimize the extraction process of Xinyi Powder by taking crushing particle size, extraction times, the amount of water added and extraction time as the investigation factors. L 9(3 4) orthogonal test was used to optimize the inclusion process of volatile oil in Xinyi Powder. Results:The optimal extraction process of ambi-extracting of Xinyi Powder was as follows: the slices were not crushed, 10 times the amount of water was added, and extracted for 3 hours; the best inclusion process of volatile oil as follows: β-cyclodextrin:water=1:25, β-cyclodextrin:volatile oil=6:1, inclusion temperature 35 ℃, inclusion time 3 hours.Conclusion:The ambi-extracting process and volatile oil inclusion process are simple, stable and feasible.
