Problems solved by technology

[0012] To sum up, the current raw materials for extracting solanesol are dried tobacco leaves, and most of the extraction solvents are organic solvents such as industrial n-hexane or No. Drying, which not only increases the cost, but also degrades part of the solanesol during the drying process; due to the large consumption of the extraction solvent, and the low boiling point, it is not easy to recycle, resulting in high cost of solvent use, and high product cost. At the same time, there are fire safety hazards and serious air pollution problems.

Embodiment 1

[0023] 100kg water content 16.5% offal smoke powder 80% ethanol 680kg, reflux extraction at 85°C for 2h, add NaOH 10kg after solid-liquid separation, No. 6 solvent oil 380kg, saponify at 82°C, extract for 2.5h, separate the oil phase, add water to the oil phase After washing 27 kg, wash with 5 kg of 80% ethanol, and recover the solvent from the oil phase after washing to obtain 2 kg of liquid viscous substance with a content of solanesol of 25.6%.

Embodiment 2

[0025] Add 600kg of 85% ethanol to 100kg moldy cut tobacco with water content of 14.2%, reflux and extract at 85°C for 1.5h, add KOH 6kg after solid-liquid separation, 300kg of No. 6 solvent oil, saponify and extract at 82°C for 2h, separate the oil phase, add water to the oil phase After washing 30 kg, wash with 5 kg of 80% ethanol, and recover the solvent from the oil phase after washing to obtain 2.5 kg of liquid viscous substance with a content of solanesol of 23.5%.

Embodiment 3

[0027] Add 400kg of methanol to homogenize 200kg of remaining tobacco leaves with a water content of 50.6%, then add 600kg of methanol, reflux at 65°C for 1.5h, add 12kg of NaOH after solid-liquid separation, 500kg of No. 6 solvent oil, saponify and extract at 65°C for 2h, separate The oil phase was washed with 35 kg of water and then washed with 5 kg of 80% ethanol. The solvent was recovered from the oil phase after washing to obtain 3 kg of liquid viscous substance with a content of solanesol of 26.5%.

Abstract

Disclosed is a process for extracting solanesol from tobacco which comprises, using moldy cigarette with moisture percentage below 50%, minced cigarette or residue tobacco leaf after collection as raw material, return flow extracting with alcohol-containing solvent, obtaining extract liquid through filtration, charging hydrocarbon solvent and alkali into the extract for saponification reaction, isolating hydrocarbon solvent phase after end of reaction, then washing the hydrocarbon solvent phase with water and 80% ethanol in sequence, finally concentrating the extracted hydrocarbon solvent phase. The extracting process requires no drying procedure and less energy consumption, the saponification and abstraction can be completed simultaneously.

Description

Technical field: [0001] The invention relates to the field of natural product chemistry, in particular to a method for extracting solanesol from tobacco. Background technique: [0002] In industry, solanesol is a synthetic coenzyme Q 10 and vitamin K 2 necessary raw materials. coenzyme Q 10 It is a natural antioxidant produced by the cells themselves, an activator of cell metabolism, and can improve the immunity of the organism. Recent studies have shown that coenzyme Q 10 It has a unique curative effect in the treatment of cardiovascular diseases, and has a significant curative effect in the treatment of scurvy, duodenal ulcer and gastric ulcer, necrotizing periodontitis, and viral hepatitis. The results of animal experiments show that coenzyme Q 10 It has anti-tumor effect and is clinically used to treat patients with advanced to acute cancer. Coenzyme Q 10 Tablets have been used effectively in the treatment of circular alopecia, emphysema, and to some extent in the ...
