Embodiment 1
[0036]Method: Weigh 4g x 5 parts of HP-β-CD (Xi'an Deli Biochemical Co., Ltd., batch number 20051202), add 25ml of absolute ethanol (No. The mass ratio of host and guest was shown by adding summer-free total alkali powder, stirring magnetically at room temperature for 2.5 hours, rotating and concentrating to dryness at 45°C, and drying under reduced pressure at 50°C to obtain a yellow solid powder.
[0037]
Embodiment 2
[0039] Method: Weigh 4g x 5 parts of HP-β-CD, add the corresponding volume of absolute ethanol to the concentration of HP-β-CD shown in the table below to dissolve, add 0.25g summer free total alkali powder each, and stir magnetically at room temperature After 2.5 hours, it was concentrated to dryness at 45°C by rotation, and dried under reduced pressure at 45°C to obtain a yellow solid powder.
