Abstract

The invention discloses a high-speed counter-current chromatography method for separating main aroma components in tree moss concrete, which comprises the following steps: 1) mixing n-hexane, ethyl acetate, ethanol and water in a volume ratio of (0.6-1.2):(0.6-1.2):(0.7-1.2):(0.7-1.2), vigorously vibrating, and standing until the solution is divided into two layers, wherein the upper layer is a stationary phase, and the lower layer is a mobile phase; 2) dispersing the tree moss concrete with the mobile phase to obtain a sample solution to be separated; and 3) separating the sample solution by high-speed counter-current chromatography, collecting the corresponding fraction according to the ultraviolet absorption spectrum, and carrying out solvent removal technique on the fraction to obtain a cigarette additive in which the relative content of the main aroma components in the tree moss concrete is higher than 85%. The impurities in the original tree moss concrete are removed, and no new impurities and toxic substances are introduced into the cigarette additive, thereby obviously improving the inherent esthetic quality of the cigarette; and thus, the cigarette additive has wide application prospects in cigarette perfuming.

Description

technical field [0001] The present invention relates to a method for separating components of natural flavors. More specifically, it relates to a method for separating main aroma components in tree moss extract and its application in cigarette flavoring. Background technique [0002] Tree moss extract (treemoss concrete) is obtained by using a tea-stained lichen plant belonging to the Usneaceae genus Usnea as a raw material and subjected to certain processing techniques such as petroleum ether or benzene extraction. Because of its unique natural green fragrance and strong resinous smell of mosses, it is often used as a natural fragrance raw material for tobacco additives and daily cosmetics. It is an important lichen fragrance in the international market of natural fragrances. [0003] The composition of extract spices is complex, and its quality and composition are not only related to plant species, but also vary with soil composition, climatic conditions, growing season, ...
