[0025] A preparation method of clematis extract, comprising the following steps:
[0026] (1) Grinding: Dry the clematis raw material to be extracted at 40-70° C., and grind it into clematis powder with a particle size of 150-420 μm, so as to obtain more effective extraction in the subsequent process.
[0027] (2) Negative pressure cavitation method extraction: the Aurantia clematis powder is added in the cavitation column, and a mixed solvent of pure water and ethyl acetate or a mixed solvent of pure water and cyclohexane are added to carry out negative pressure cavitation method Extraction; in a preferred embodiment: the mass ratio of clematis powder to the mixed solvent is 1:6 to 1:15, wherein: the volume ratio of ethyl acetate to water in the mixed solvent is 2:1 to 1:4, The volume ratio of cyclohexane to water is 1:1~1:6; in negative pressure cavitation extraction, the extraction pressure is set at -0.06MPa~-0.04MPa, the extraction temperature is between 20~25°C, repeat ...
Embodiment 1
[0037]Accurately weigh 30 g of dried Clematis clematis raw material, and crush it to 150 μm Clematis clematis powder at 50 ° C; put the powder into a cavitation column, add 300 mL of ethyl acetate and pure Mix solvent with water, set the extraction pressure to -0.04MPa, extract at 25°C for 30min, filter the extract through a 200-mesh sieve and retain it, add 150mL of ethyl acetate and pure Mixed solvent of water, extract again at 25°C for 30 minutes, repeat the extraction twice under this condition, filter the extract through a 200-mesh sieve and mix it with the filtrate obtained before; add ammonia with a volume fraction of 10% to the mixed filtrate dropwise Aqueous solution, adjust the pH to 9, shake and mix the filtrate for 15min, collect the aqueous phase solution in the lower layer after standing still; centrifuge the obtained aqueous phase solution at a speed of 3000rpm for 10min to obtain a supernatant; Concentrate under reduced pressure to 30mL and put it on a 732 cati...
Embodiment 2
[0039] Accurately weigh 30 g of dried Clematis clematis raw material, and crush it to 300 μm Clematis clematis powder at 60 ° C; put the powder into a cavitation column, add 400 mL of cyclohexane and pure Mix solvent with water, set the extraction pressure to -0.05MPa, extract at 20°C for 40min, filter the extract through a 200-mesh sieve and keep it, and add 250mL of cyclohexane with a volume ratio of 1:3 and pure Mix solvent with water, extract again at 20°C for 40 minutes, repeat the extraction twice under this condition, filter the extract through a 200-mesh sieve and mix it with the filtrate obtained before; add ammonia with a volume fraction of 20% to the mixed filtrate dropwise Aqueous solution, adjust the pH to 9.5, shake and mix the filtrate for 25min, collect the aqueous phase solution in the lower layer after standing still; centrifuge the obtained aqueous phase solution at a speed of 4000rpm for 15min to obtain a supernatant; Concentrate under reduced pressure to 4...
