Embodiment 1
[0037] The preparation method of Trichosanthes bark extract is:
[0038] (a) Pulverize the Trichosanthes peel into the Trichosanthes peel powder with a particle size of 250 μm;
[0039] (b) Take 100g of the powder in (a) and add 500ml of water to extract for 8 minutes under the condition of 300MPa, release the pressure, collect the filtrate after filtration, and concentrate the filtrate for the first time to a relative density of 1.1 at 50°C and a vacuum of 0.08MPa , to obtain the first extract;
[0040] (c) After taking the first extract and dialysis with a 22mm semi-permeable membrane at 5°C, collect the retained liquid, react with a mixed solution of chloroform-n-butanol with a volume ratio of 4:1 to deproteinize, collect the water layer, and filtrate Concentrate for the second time to a relative density of 1.1 at 50°C with a vacuum of 0.08 MPa to obtain the second extract;
[0041] (d) Take the second extract and add ethanol with a concentration of 95%, let it stand for ...
