Embodiment 1

[0021] Accurately weigh 200g of eagle tea, dry it at 45°C, and grind it to a coarse powder with a particle size of 200um. Concentrate under pressure to 400g, add ethanol to make the alcohol content in the concentrated solution reach 50%, stir evenly, and stand still below 4°C for 8 hours. Filter the mixed solution, pass the filtrate through a hollow fiber membrane with a molecular weight cut-off of 4k Daltons, collect the permeate, concentrate under reduced pressure to a viscous solution, which is Eagle Tea Extract I.

Embodiment 2

[0023] Accurately weigh 200g of eagle tea, dry it at 55°C, and crush it to a coarse powder with a particle size of 300um, add 2.4kg of water, extract by ultrasonic wave for 10min, ultrasonic power 800W, ultrasonic frequency 40KHz, constant temperature 45°C, filter the extract, reduce Concentrate under pressure to 400g, add ethanol to make the alcohol content in the concentrated solution reach 60%, stir evenly, and stand still below 4°C for 16 h. Filter the mixed solution, pass the filtrate through a hollow fiber membrane with a molecular weight cut-off of 6k Daltons, collect the permeate, and concentrate under reduced pressure to a viscous solution, which is Eagle Tea Extract II.

Embodiment 3

[0025] Accurately weigh 200g of eagle tea, dry it at 65°C, and crush it to a coarse powder with a particle size of 400um, add 3.0kg of water, extract by ultrasonic wave for 30min, ultrasonic power 1000W, ultrasonic frequency 60KHz, constant temperature 55°C, filter the extract, reduce Concentrate under pressure to 400g, add ethanol to make the alcohol content in the concentrated solution reach 70%, stir evenly, and stand still below 4°C for 24 hours. Filter the mixed solution, pass the filtrate through a hollow fiber membrane with a molecular weight cut-off of 8k Daltons, collect the permeate, and concentrate under reduced pressure to a viscous solution, which is Eagle Tea Extract III.

Abstract

The invention discloses hawk tea extract, a preparation method thereof, and an application of the extract in cigarette and relates to the plant extract and application thereof. The preparation method for the hawk tea extract includes steps that (1) pre-processing; (2) ultrasonic extracting; (3) purifying through ethanol; (4) membrane separation; (5) condensing. The hawk tea extract is diluted through organic solvent without toxicity and pungent smell, and the dilution ratio is 10 to 15 times; before preparing the cigarette, the hawk extract diluted liquid is sprayed to the surface of the tobacco leaf according to the mass ratio of 0.1-1%. The hawk tea extract is convenient to use and capable of greatly improving the interior quality of the cigarette, reducing the offensive odor, increasing the smoke gas amount and improving the mouth feel; the interior quality of the cigarette is greatly improved.

Description

technical field [0001] The invention relates to plant extraction and its application, in particular to an eagle tea extract, its preparation method and the application of the extract in cigarettes. Background technique [0002] Eagle tea is a woody plant of Lauraceae, which contains various ingredients, such as amino acids, mineral elements, vitamin C, vitamin B1, vitamin B2, flavonoids, polyphenols, caffeine and other substances. "Compendium of Materia Medica" has records such as "relieving cough, eliminating phlegm, relieving asthma, relieving heat and quenching thirst". [0003] For the extraction of eagle tea, in the traditional process, water and alcohol are generally used to extract the eagle tea, and then separation and purification are carried out, followed by concentration and drying to obtain the extract. However, the active ingredient content of the eagle tea extract obtained by this method is low, which is not suitable for industrial implementation. And the eag...
