Embodiment 1

[0030] Eluent pretreatment: Use a re-distillation device to re-distill petroleum ether and ethyl acetate to remove high-boiling impurities. The redistillation temperature of petroleum ether is 80°C. The redistillation temperature of ethyl acetate was 90°C.

[0031] Wet column packing: Weigh 120g of silica gel into a 500mL beaker, add a mixed solvent of petroleum ether and ethyl acetate with a volume ratio of 12:1, stir well and pour it into a Φ0.26x70cm separation column at one time, and rinse repeatedly to make The silicone is evenly firm.

[0032] Sample loading: Weigh 0.6g of Peruvian extract into a 50mL eggplant-shaped bottle, add 2mL of ethyl acetate to dissolve and dilute, and then spread the diluted Peruvian extract on the silica gel surface slowly and evenly with a disposable dropper.

[0033] Gradient elution: use DHL-N computer digital display timing constant flow pump to control the flow rate of eluent to 3mL / min, according to the volume ratio of petroleum ether a...

Abstract

The invention provides a method for separating and preparing characteristic components of Peruvian extract, using Peruvian extract as a raw material, silica gel as an adsorbent, and petroleum ether (60-90° C.)-ethyl acetate as an eluent system. The various volatile components of the extract were separated and prepared into the characteristic components of the Peruvian extract. The characteristic components of the Peruvian extract were detected by GC-MS to clarify the composition and content of each component. Dissolve and dilute, add the diluted components and shredded tobacco to blank cigarettes at a mass ratio of 0.5-2‰ with a flavor injection machine for sensory evaluation, and clarify the effect of each component on improving the sensory quality of cigarettes and the applicable amount in cigarettes. The invention is efficient, simple and low in price, and the characteristic components of the prepared Peruvian extract have good application effects in cigarettes.

Description

technical field [0001] This patent relates to the field of separation and preparation of volatile components of Peruvian extract, in particular to establishing a method for preparing characteristic components of Peruvian extract. Background technique [0002] Peruvian gum belongs to the leguminous plant, up to 30 meters high, distributed in the forests of Salvador and Honduras on the Pacific coast of central America. Peru balsam is a yellow to dark brown paste produced by the internal tissues of the Peruvian gum tree after damage. Balsam of Peru has the effect of promoting wound healing, repelling worms, and diuretic. The distillate of balsam peru is commonly used in the formulation of cosmetic fragrances and soap fragrances, but it can cause allergic contact dermatitis. The Peruvian extract can be obtained by extracting the Peruvian balsam with an organic solvent such as benzene or ether. The Peruvian extract has a yellow to light brown viscous paste with the smell of bal...
