Embodiment 1
[0053] 1 prescription
[0054]
[0055] 2 Preparation method
[0056] Pulverize 170g of Brucea javanica medicinal material through 18 mesh sieve, add 12 times petroleum ether, extract 3 times, extract 8 hours each time. The extracts were combined, and the petroleum ether was removed by rotary evaporation to obtain crude cava oil. Add 5% activated charcoal to the crude jacaranda oil for decolorization, and nitrogen gas under reduced pressure to remove residual petroleum ether for later use. Take 62g of MCT and mix 31mL of the obtained Brucea javanica oil to make the oil phase, take 277g of surfactant RH40 and 93mL of absolute ethanol to make the surfactant phase, slowly add 308mL of distilled water dropwise after the two phases are mixed, and make about 770ml of microemulsion for later use.
[0057] Another 42g of HPMC and 6g of lactose were mixed with the prepared javanica javanica oil microemulsion, dried at 45°C for 80 minutes, granulated, and packed with 1000 capsules ...
Embodiment 2
[0059] 1 prescription
[0060]
[0061] 2 Preparation method
[0062] Pulverize 170g of Brucea javanica medicinal material and pass through a 16-mesh sieve, add 10 times of petroleum ether, extract 3 times, and extract 9 hours each time. The extracts were combined, and the petroleum ether was removed by rotary evaporation to obtain crude cava oil. Add 5% activated charcoal to the crude jacaranda oil for decolorization, and nitrogen gas under reduced pressure to remove residual petroleum ether for later use. Get MCT and make javanica javanica oil 30mL and mix to make oil phase, get surfactant RH40 and dehydrated alcohol and make surfactant phase, slowly add distilled water dropwise after two phases are mixed, make microemulsion for standby.
[0063] Separately take HPMC and lactose, mix with the prepared javanica javanica oil microemulsion, dry at 50°C for 80 minutes, granulate, pack 1000 capsules, and obtain.

[0067] 2 Preparation method
[0068] Pulverize 170g of Brucea javanica medicinal material and pass through a 16-mesh sieve, add 12 times of petroleum ether, and extract 3 times for 9 hours each time. The extracts were combined, and the petroleum ether was removed by rotary evaporation to obtain crude cava oil. Add 5% activated charcoal to the crude jacaranda oil for decolorization, and nitrogen gas under reduced pressure to remove residual petroleum ether for later use. Get MCT and make javanica javanica oil 32mL and mix to make oil phase, get surfactant RH40 and absolute ethanol and mix make surfactant phase, after two phases are mixed, slowly add distilled water dropwise, make microemulsion for later use.
[0069] Separately take HPMC and lactose, mix with the prepared javanica javanica oil microemulsion, dry at 45°C for 80 minutes, granulate, pack 1000 capsules, and obtain.
