Problems solved by technology

These published patents and documents either have a single type of extraction, such as only solanesol or nicotine can be obtained, or the steps are cumbersome, and two steps are necessary to extract both solanesol and nicotine, which takes a long time and has low separation efficiency. Low purity, large amount of waste water

Embodiment 1

[0037] (1) Simultaneous extraction of solanesol and nicotine: After 50g of tobacco raw material is dried and pulverized (about 20 mesh), it is added to a circulating ultrasonic extractor, and then 500g of 0.1mol / L NaOH ethanol solution is added, and the ultrasonic power is 100W. Under the condition of temperature 50°C, ultrasonic circulation extraction was carried out for 30 minutes.

[0038] (2) Extraction and separation: After the ultrasonic extraction is completed, the ethanol extract is released, and the tobacco filter residue is removed by filtration. The filtrate is adjusted to pH 2 by hydrochloric acid solution, and then the ethanol is removed by vacuum concentration to obtain a crude solanesol nicotine mixture. The crude product mixture was separated by liquid-liquid two-phase extraction with 300 mL petroleum ether / 300 mL water. The product enriched in the petroleum ether layer is crude solanesol, and the product enriched in the water layer is crude nicotine.

Embodiment 2

[0042](1) Simultaneous extraction of solanesol and nicotine: After 100g of tobacco raw material is dried and pulverized (about 20 mesh), it is added to a circular ultrasonic extractor, and then 1200g of 0.1mol / L NaOH ethanol solution is added, and the ultrasonic power is 200W. Under the condition of temperature 60°C, ultrasonic circulation extraction was carried out for 50 minutes.

[0043] (2) Extraction and separation: After the ultrasonic extraction is completed, the ethanol extract is released, and the tobacco filter residue is removed by filtration. The filtrate is adjusted to pH 3 by hydrochloric acid solution, and then the ethanol is removed by vacuum concentration to obtain a crude solanesol nicotine mixture. The crude product mixture was separated by liquid-liquid two-phase extraction with 500 mL petroleum ether / 500 mL water. The product enriched in the petroleum ether layer is crude solanesol, and the product enriched in the water layer is crude nicotine.

Embodiment 3

[0047] (1) Simultaneous extraction of solanesol and nicotine: After 100g of tobacco raw material is dried and pulverized (about 20 mesh), it is added to a circulating ultrasonic extractor, and then 1500g of 0.1mol / L NaOH ethanol solution is added, and the ultrasonic power is 300W. Under the condition of temperature 60°C, ultrasonic circulation extraction was carried out for 60 min.

[0048] (2) Extraction and separation: After the ultrasonic extraction is completed, the ethanol extract is released, and the tobacco filter residue is removed by filtration. The filtrate is adjusted to pH 4 by hydrochloric acid solution, and then the ethanol is removed by vacuum concentration to obtain a crude solanesol nicotine mixture. The crude product mixture was separated by liquid-liquid two-phase extraction with 500 mL petroleum ether / 500 mL water. The product enriched in the petroleum ether layer is crude solanesol, and the product enriched in the water layer is crude nicotine.

Abstract

The invention discloses a method for simultaneously extracting and separating solanesol and nicotine from a tobacco. The method comprises the following steps of: (1) extracting the solanesol and the nicotine at the same time; (2) extracting and separating; (3) separating and purifying the solanesol; (4) separating and purifying the nicotine. Because the nicotine is separated and extracted and the solanesol is saponified and extracted at the same time, the extraction steps are simplified greatly, and the consumption of time and solvents is saved. Compared with the prior art, the method disclosed by the invention is efficient, ensures that more products are extracted and less waste liquid is discharged, is simple in step and is an environmentally-friendly production technology.

Description

technical field [0001] The invention relates to the technical field of tobacco deep processing, in particular to a method for simultaneously extracting and separating solanesol and nicotine from tobacco. Background technique [0002] Tobacco is an important economic crop. It belongs to the annual herbaceous plant of Solanaceae with alternate single leaves. It is native to South America and was introduced to China in the middle of the 16th century. my country is the country with the largest tobacco production and consumption in the world, accounting for more than one-third of the global total. It has become a conclusion that smoking is harmful to health. With the rise of the world tobacco control movement, the use of tobacco in cigarettes will also be greatly weakened. However, as a highly productive natural plant resource, tobacco's potential health benefits are also very broad. In addition to protein and sugar, tobacco also contains important medicinal components such as ...
