preparation example Construction

[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...

Abstract

Provided are a preparation method of a clematis extract and its application in cigarettes and cigarettes. The preparation method comprises the following steps: (1) drying the clematis raw material to be extracted at 40-70° C., and crushing it into clematis powder with a particle size of 150-420 μm; (2) making the clematis powder Add the powder into the cavitation column, and add a mixed solvent to carry out negative pressure cavitation extraction; (3) mix the crude extract for 10-40 minutes, let it stand for stratification, and take the aqueous phase solution; (4) depressurize the aqueous phase solution Concentrating to 5% to 15% of the volume of the aqueous phase solution; (5) Purifying the Clematis clematis extract with 732 cation exchange resin to obtain the Clematis clematis extract; (6) Concentrating the Clematis clematis extract under reduced pressure to obtain Clematis extract. The invention can more effectively obtain the active ingredients contained in the extract of Aurantia clematis, reduce the ingredients that reduce the quality of cigarettes contained therein, and can be more effectively utilized in the technical field of cigarettes.

Description

technical field [0001] The invention belongs to the technical flavor field for cigarettes, and in particular relates to a preparation method of a clematis extract and its application in cigarettes and cigarettes. Background technique [0002] Clematis aureus, also known as golden thread orchid, golden silkworm, and chrysanthemum, is a rare perennial Chinese herbal medicine. Clematis is rich in active ingredients such as flavonoids, polysaccharides, glycosides, steroids, cardiac glycosides, amino acids, organic acids, alkaloids and various trace elements. Auranthus clematis has a faint sweet aroma, has the functions of cooling blood and expelling wind, dehumidifying and detoxifying, relieving cough, and analgesic, and is widely used among the people. [0003] Due to the various pharmacological effects of clematis clematis, the extract of clematis clematis is usually used in research in the field of medical care, but the application in the fields of tobacco technical spices a...
