Embodiment 1

[0033] Mix n-hexane, ethyl acetate, ethanol, and water according to the volume ratio of 0.9:0.9:1:1, shake vigorously for 15 minutes, and after standing for 2 hours, the mixed solution is divided into two layers. The upper layer after layering is used as the stationary phase, and the lower layer is used as the Mobile phase: Weigh 1g of the tree moss extract sample, add 20ml of mobile phase, stir and ultrasonically disperse for 10min to obtain the sample solution to be separated.

[0034] A TBE-300 semi-preparative high-speed countercurrent chromatograph (Shanghai Tongtian Biochemical Technology Co., Ltd.) was used. The instrument was equipped with a pump, a 10-30ml sampling valve, an ultraviolet detector and a recorder. Its multilayer winding polytetrafluoroethylene tube The column capacity is about 300ml. First fill the separation column of high-speed countercurrent chromatography with stationary phase at a flow rate of 10mL / min, then turn on the speed controller to make the ...

Abstract

The invention discloses a high-speed countercurrent chromatographic method for separating a terpene component in a tree moss extract. The method comprises the following steps: 1, mixing n-hexane with ethyl acetate, ethanol and water according to a volume ratio of 0.7-1.1:0.7-1.1:0.8-1.1:0.8-1.1, carrying out acute oscillation, and allowing the obtained mixture to stand in order to form two layers comprising an upper layer used as a stationary phase and a lower layer used as a mobile phase; 2, dispersing the tree moss extract by the mobile phase to obtain a sample solution to be separated; and 3, separating the sample solution through high-speed countercurrent chromatography, collecting a corresponding fraction according to an ultraviolet absorption map, and carrying out solvent removal on the obtained fraction to obtain the terpene component with the relative content of above 90%. The method has the advantages of mild conditions, high separation efficiency, good stability, simple process, and easy realization of popularization use and industrial production.

Description

technical field [0001] The invention relates to the technical field of separation methods of natural fragrance components, and more specifically relates to a method for separating terpene components from tree moss extract by applying high-speed countercurrent chromatography. Background technique [0002] Tree moss extract (treemoss concrete) is a brown-green paste, which is obtained by using a tea-stained lichen plant belonging to the Usneaceae family as a raw material, and through certain processing techniques such as petroleum ether or benzene extraction. . Treemoss extract is often used as a tobacco additive and natural fragrance raw material for daily cosmetics due to its unique natural green fragrance and strong resinous smell of liverwort. It is an important lichen spice in the international market of natural spices. [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 com...
