preparation example Construction

[0023] In one embodiment, the preparation method of Cornus officinalis extract comprises the following steps: 1) Ultrasonic-microwave synergistic extraction: dry Cornus officinalis powder with a particle size of 150-420 μm and 50 wt % ~80 wt% ethanol solution is put into the cavity of ultrasonic-microwave synergistic extraction equipment for extraction; after the extraction is completed, cool down, use a 150-200 mesh screen to filter the extract to obtain a filtrate, and concentrate the filtrate to obtain a concentrate; 2 ) centrifugation: dissolving the concentrated solution in water with 2 to 3 times the mass of the concentrated solution, and centrifuging to obtain a supernatant; 3) column chromatography: passing the supernatant through a chromatographic column, first using 10wt% to 30 wt% ethanol or water for 2 to 6 times the column volume to elute impurities, and then 50 wt% to 70 wt% ethanol for 2 to 6 times the column volume to elute and collect the eluate; 4) Concentrati...

Embodiment 1

[0033] Accurately weigh 200g of Cornus officinalis, dry at 45°C, and crush it to a coarse powder with a particle size of 250μm, add 1.6kg of ethanol solution with a concentration of 70%, and conduct ultrasonic-microwave collaborative extraction for 15min, with ultrasonic power 50W, microwave power 300W, constant temperature 55 ℃, the extract was filtered through a 200-mesh sieve, and concentrated under reduced pressure until the relative density was 1.12 at 25°C to obtain a concentrated solution; the concentrated solution was dissolved in water with twice the quality of the concentrated solution, and centrifuged at a centrifugal speed of 4000rpm for 20 minutes to obtain Supernatant: The supernatant is dynamically adsorbed by polyamide resin, and the adsorption and deflow rate is 1BV / h. After adding the sample, first use 5 times the column volume of 20% ethanol to elute the impurities, and then use 4 times the column volume of 70% ethanol to elute the impurities. % ethanol eluti...

Embodiment 2

[0035]Accurately weigh 200g of Cornus officinalis, dry at 50°C, and crush it to a coarse powder with a particle size of 420μm, add 1.2kg of 50% ethanol solution, ultrasonic-microwave collaborative extraction for 25min, ultrasonic power 50W, microwave power 250W, constant temperature 60 ℃, the extract was filtered through a 200-mesh sieve, and concentrated under reduced pressure until the relative density was 1.15 at 25°C to obtain a concentrated solution; the concentrated solution was dissolved in water twice the quality of the concentrated solution, and centrifuged at a centrifugal speed of 6000rpm for 10 minutes to obtain Supernatant: the supernatant is dynamically adsorbed by AB-8 macroporous adsorption resin, the adsorption flow rate is 0.5BV / h, after the sample is loaded, first use 5 times the column volume of 20% ethanol to elute the impurities, and then use 4 times the column volume The volume of 80% ethanol was eluted, and the eluate was collected. The amount of AB-8 ma...

Abstract

The invention discloses a method for preparing cornus officinalis extract, an application in cigarettes and the cigarette. The method for preparing the cornus officinalis extract comprises the following steps: preparing the cornus officinalis; using the ultrasonic wave to extract collaborated with microwaves; extracting the liquid and concentrating; centrifuging and separating; separating by column chromatography; and concentrating to obtain the cornus officinalis extract. The cornus officinalis extract prepared by the invention is applied to the cigarettes, the use is convenient, the quality and level of the cigarette are improved, the smoke is rich and sweet, and the palate aftertaste is improved. The method combines the advantages of the ultrasonic wave with the homogenization of the microwave vibration, so the stress of each point in the sample medium is the same, the range of the target extract is large, the combination force of the target object and the sample substrate is reduced, the process that the target object enters the liquid from the solid phase is accelerated, and the sample process quantity is large. The cornus officinalis extract is obtained after extracting and refining by column chromatography with gentle conditions, which provides a new perfume material for natural tobaccos.

Description

technical field [0001] The present invention relates to plant extraction and application thereof, in particular to a preparation method of cornus officinalis extract and its application in cigarettes and cigarettes containing the cornus officinalis extract. Background technique [0002] Cornus officinalis is the dried and mature pulp of Cornus officinalis Sieb.Ct Zucc., which is a plant of the family Cornaceae. "New Compendium of Materia Medica" records: taste sour and astringent, gas flat, slightly warm, non-toxic. Go into kidney, liver two warps. Listed as a middle grade, it has the effects of nourishing the liver and kidney, astringent and astringent, and is used for dizziness, tinnitus, liver deficiency, cold and heat embolism. All editions of "Chinese Pharmacopoeia" are recorded. [0003] Modern medical analysis and research prove that Cornus officinalis mainly contains volatile components, iridoids, organic acids, tannins and other components, among which volatile c...
