Embodiment 1
[0043] Example 1 Preparation of orlistat sulfobutyl ether-β-cyclodextrin inclusion compound
[0044] Preparation of orlistat sulfobutyl ether-β-cyclodextrin inclusion compound by grinding method comprises the following steps:
[0045] Take 10g of sulfobutyl ether-β-cyclodextrin, add it into 30mL of water medium, and grind it evenly; take 0.8g of orlistat and dissolve it in 2.4mL of ethanol to obtain an ethanol solution of orlistat; His ethanol solution is slowly added to the well-ground sulfobutyl ether-β-cyclodextrin, fully ground and then dried to obtain orlistat sulfobutyl ether-β-cyclodextrin inclusion compound.
Embodiment 2
[0046] Example 2 Preparation of orlistat sulfobutyl ether-β-cyclodextrin inclusion compound
[0047] Ultrasonic method prepares orlistat sulfobutyl ether-β-cyclodextrin inclusion compound, comprises the following steps:
[0048] Dissolve 25g of sulfobutyl ether-β-cyclodextrin in water medium to make a saturated solution; dissolve 1g of orlistat in acetone, slowly add it to the saturated solution of sulfobutyl ether-β-cyclodextrin, mix well After homogenization, ultrasonic treatment was performed for 6 hours, filtered, washed and dried to obtain orlistat sulfobutyl ether-β-cyclodextrin inclusion compound.
Embodiment 3
[0057] Example 3 Preparation of orlistat sulfobutyl ether-β-cyclodextrin inclusion compound
