Embodiment 1
[0110] Embodiment 1: the preparation of Rosa roxburghii fruit active extract: get Rosa roxburghii fresh fruit 1kg, reflux extraction 2 times with 80% ethanol, each 2 hours, the amount of alcohol added is 10 times of raw material weight, filters, merges filtrate, reclaims Ethanol until there is no alcohol smell, add water to dilute the extract to a relative density of 1.15, extract three times with ethyl acetate, the ratio of ethyl acetate to water is 1:1, combine the ethyl acetate layers, recover ethyl acetate, add water and sonicate Or heat to disperse, filter with suction, wash the precipitate with water for 3 times, combine the filtrate, and vacuum-dry the filtrate to obtain active extract B, and vacuum-dry the precipitate to obtain active extract A.
Embodiment 2
[0111] Embodiment 2: the preparation of Rosa roxburghii fruit active extract: get Rosa roxburghii fruit 1kg, reflux extraction with 95% ethanol for 3 hours, the amount of alcohol added is 12 times of raw material weight, filters, merges filtrate, reclaims ethanol to no alcohol smell , add water to the extractant with a relative density of 1.25, extract 4 times with ethyl acetate, the ratio of ethyl acetate to water is 0.5:1, combine the ethyl acetate layers, recover ethyl acetate, add water and ultrasonically or heat to disperse, Suction filtration, washing the precipitate with water for 4 times, combining the filtrates, and drying the filtrate and the precipitates in a microwave vacuum to obtain active extract B and active extract A respectively.
Embodiment 3
[0112] Embodiment 3: the preparation of Rosa roxburghii fruit active extract: get Rosa roxburghii fresh fruit 1kg, reflux extraction with 70% methanol 3 times, each 1.5 hours, the amount of alcohol added is 6 times of raw material weight, filters, merges filtrate, reclaims Methanol until there is no alcohol smell, add water to dilute the extract to a relative density of 1.1, extract 4 times with n-butanol, the ratio of n-butanol to water is 1:1, combine the n-butanol layers, recover n-butanol, add water and sonicate Or heat to disperse, filter with suction, wash the precipitate with water for 3 times, combine the filtrate, and dry the filtrate and the precipitate under reduced pressure and vacuum to obtain active extract B and active extract A respectively.
