Embodiment 1
[0055] Measure 9ml of Goose Bubivorous volatile oil and 1ml of peppermint oil, mix well, and set aside; weigh 80g of β-cyclodextrin and add it to 800ml of water, stir and suspend, heat to 65°C, the solution gradually becomes clear, cool down to 40°C, and slowly Add the above mixed oil dropwise. After the dropwise addition, keep warm at 40°C and stir for 2 hours for clathrate. After inclusion, put it in a refrigerator at 4°C, cool down for about 20 hours, and white powder precipitates. Suction filtration, wash the precipitate with water 3 times, 100ml each time, and then wash 3 times with absolute ethanol, 100ml each time, and dry in an oven at 40°C for 4 hours to obtain 55g of clathrate.
[0056] Determination of oil content of inclusion compound: Weigh 5.0g of inclusion compound, weigh it accurately, put it in a 500ml round bottom flask, add 300ml of water and a few glass beads, shake well, connect it to a volatile oil detector, and measure it according to the method of volat...
