Method of extracting jianiol from tobacco

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 ...

AI Technical Summary

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.
