Extraction of Volatile Oil from Chrysanthemum indicum and Preparation Techniques of Its β- cyclodextrin Inclusion Compound

OBJECTIVE： To optimize the extraction conditions of volatile oil from Chrysanthemum indicum and the processing techniques of its β- yclodextrin（β- CD） inclusion compound.METHODS：The extraction conditions of volatile oil from Chrysanthemum indicum was optimized taking soaking time, ultrasonic treatment time, water amount as influencing factors and with the yield of the volatile oil as index.The processing techniques of the β- yclodextrin （β CD） inclusion compound was optimized taking the ratio of β - CD to volatile oil, the time and temperature of the inclusion process as indexes and with the yield of the inclusion compound and the inclusion rate of the volatile oil as indexes. RESULTS： The optimal process for oil extraction was as follows：the soaking time = 1.5 h, the ultrasonic treatment time = 40 min, heating time = 6 h,water amount = 600 mL.The optimal processing conditions for（β- CD） inclusion compound of Chrysanthemum indicum were as follows： the ratio of β- CD to volatile oil = 8 ： 1, the inclusion time of the compound was 2 hours at 40 ℃. CONCLUSION：High extraction yield of vlatile oil and stable inclusion compound were obtained from the above method.
