Preparation method and application of compound cimicifugamide

Abstract

The invention provides a preparation method for a compound I and the application of the compound I as a tobacco flavor modifier. The method comprises the following steps of: extracting cured tobacco leaves which serve as a raw material by using water, an organic solvent or a mixed solvent consisting of the water and the organic solvent, concentrating extract under reduced pressure, dissolving concentrate in the water, performing extraction sequentially by using petroleum ether, ethyl acetate and N-butanol, concentrating extract under reduced pressure, and chromatographically separating N-butanol extract by using a macroporous adsorption resin, silica gel and a C-18 silica gel column to obtain the compound. When the compound is added into tobacco shreds, tobacco leaves, expanded tobacco shreds and flaky tobacco shreds, the tobacco flavor can be remarkably improved, smoke can be rounded, remaining taste can be improved, and the inner quality of the tobacco can be improved. The compound I is extracted from the tobacco for the first time, is low in volatility, is flavorless at normal temperature, releases flavor components only after glucosidic bonds of the compound are split when a cigarette is lighted, and has the characteristic of flavor releasing persistence.

Description

technical field [0001] The invention relates to a preparation method and application of a tobacco aroma improving agent, in particular to a preparation method and application of a glycoside compound cimicamide isolated from tobacco leaves and having improved tobacco aroma. Background technique [0002] With the upsurge of the "anti-smoking" movement, smoking and health have attracted more and more attention from the society, and people's demand for low-tar and low-harm cigarettes has become increasingly urgent. Cigarette taste is an important manifestation of tobacco quality, but it will be accompanied by the loss of cigarette flavor while reducing tar. With the in-depth advancement of harm reduction and tar reduction, the tobacco industry has increasingly prominent requirements for aroma compensation brought about by harm reduction and tar reduction. Therefore, finding additives to enhance cigarette flavor to compensate for the flavor loss of low-tar cigarettes is an urgent...

AI Technical Summary

Problems solved by technology

At present, there are not many studies on the glycoside-bound flavor components in tobacco. This may be that on the one hand, the influence of glycoside flavor precursors in tobacco on the taste of tobacco has not been paid attention to. On the other hand, glycoside compounds are secondary metabolites of tobacco. There are many substances, and they are very close to oligosaccharides, pectin, amino acids, pigments and other substances, and it is difficult to obtain standard samples. Therefore, the quantitative analysis and application research and development of tobacco glycosides are relatively difficult
