Embodiment 1

[0028] This example provides a tobacco extract and e-cigarette liquid. The preparation method is as follows: add 500 ml of 85 vol% ethanol to 50 g of Sangzhi B3F, extract at room temperature for 1 day, filter, and concentrate the filtrate to dryness to obtain an ethanol extract. Add 40 ml of hot ethanol to dissolve the ethanol extract, and then place the dissolved solution at 4°C for 2 hours to freeze to precipitate a precipitate, filter, and concentrate to 10 ml to obtain extract I. The shredded tobacco extracted by ethanol is ultrasonicated for 30 minutes at room temperature with 500 ml of water, and the water extract is obtained by filtration. The water extract is first degreased with 300 ml of n-hexane. Extract and collect the water phase (degreasing process, the same below); the water phase was then extracted with 300 ml of dichloromethane, and the dichloromethane phase was concentrated to 10 ml under reduced pressure at 30°C to obtain Extract II. Take 2 ml of extract I a...

Embodiment 2

[0031] This example provides a tobacco extract and e-cigarette liquid. The preparation method is as follows: add 2000 ml of 95 vol% ethanol to 180 g of shredded Zimbabwean tobacco, extract at room temperature for 1 day, filter, add 150 ml of hot ethanol to dissolve the filtrate after concentration , to obtain the ethanol extract, placed at 4 ° C for 2h to freeze and precipitate the precipitate, filtered, concentrated to 30 ml, and the extract I was obtained. The shredded tobacco extracted by ethanol was ultrasonicated for 30 minutes at room temperature with 2000 ml of water, and the water extract was obtained by filtration. The water extract was first degreased with 1000 ml of petroleum ether, and then extracted with 1000 ml of ethyl acetate. Concentrate under reduced pressure to 40 ml at 40°C to obtain extract II.

Embodiment 3

[0035]This example provides a tobacco extract and e-cigarette liquid. The preparation method is as follows: add 800 ml of 75% ethanol to 80 g of Baishaye group formula tobacco powder, extract at room temperature for 1 day, filter, and concentrate the filtrate to dryness to obtain ethanol For the extract, 60 ml of hot ethanol was added to dissolve the ethanol extract, and the dissolved solution was placed at 4° C. for 2 hours to freeze to precipitate a precipitate, filtered, and concentrated to 15 ml to obtain extract I. The shredded tobacco extracted by ethanol was ultrasonicated for 30 minutes at room temperature with 800 ml of water, and the water extract was obtained by filtration. The water extract was first degreased with 500 ml of petroleum ether, and then extracted with 500 ml of dichloromethane. Concentrate under reduced pressure to 20 ml at 40°C to obtain extract II. Take 5 ml of extract I and 8 ml of extract II, mix them, and dilute them 3 times with a base solvent t...

Abstract

The invention discloses tobacco extract and electronic cigarette liquid. A preparation method of the tobacco extract comprises the following steps that (1), tobacco powder or/and tobacco shreds serve as raw materials, the raw materials are extracted with ethanol water with the volume fraction more than 75%, an extracting solution is concentrated to obtain ethanol extract, ethanol is used for dissolving the ethanol extract, then the ethanol extract is frozen, dissolved out, precipitated and filtered, and filter liquor is concentrated to obtain extract I; (2), the raw materials extracted with the ethanol are extracted with water, water extract is obtained, the water extract is leached with a solvent A, water phases are collected and then are used for leaching a solvent B, and organic phases are collected and concentrated to obtain extract II, wherein the solvent A is one or more of petroleum ether, normal hexane and cyclohexane, and the solvent B is ethyl acetate or dichloromethane; (3), the extract I and the extract II are mixed to obtain the tobacco extract. The tobacco extract keeps the tobacco aroma, the amount of aroma is full, no black residue exists after atomization, and no scorched flavor exists.

Description

technical field [0001] The invention relates to a tobacco extract and an electronic cigarette liquid, in particular to an electronic cigarette liquid with a sweet and roasted aroma, belonging to the field of electronic cigarettes. Background technique [0002] In recent years, new tobacco products such as low-temperature cigarettes and electronic cigarettes are rapidly emerging. The shape of electronic cigarette is similar to that of ordinary cigarettes. It is a device that can vaporize electronic cigarette liquid (also known as electronic cigarette oil, which is a flavor solution) into mist, giving smokers a feeling similar to smoking. [0003] E-cigarettes reduce harm to people's bodies while satisfying people's smoking habits. In a nutshell, electronic cigarettes have the following main features: first, they do not need to be burned, and are less harmful than traditional cigarettes; second, they have relatively little impact on the public environment; third, they can ada...
