Example Embodiment
[0028] Example 1
[0029] Take 100 g of Zimbabwean tobacco leaves and 800 g of petroleum ether, extract for 2 h at 40° C. under 50 kHz ultrasonic treatment, and the ultrasonic power is 120 W, and separate the filtrate and filter residue.
[0030] The filtrate was concentrated until 34.5 g of a concentrate was obtained.
[0031] In terms of weight ratio, weigh 50:1, 20:1, 10:1, 5:1, 3:1, 2:1, 1:1, 1:5 petroleum ether and ethyl acetate mixture as eluent , 500mL for each gradient. The concentrate was loaded onto a silica gel column for gradient elution, and the receiving solutions were numbered and marked according to the order in which they flowed out. A total of 155 tubes of receiving solutions were obtained, each about 26ml. Take 75-130 tubes of receiving liquid, concentrate at 45°C and 0.08MPa pressure to remove the solvent, and obtain the aromatizer.
[0032] The prepared flavoring substance is diluted with ethanol with a mass concentration of 95%, and sprayed evenly into...
Example Embodiment
[0035] Example 2
[0036] Take 100 g of Zimbabwean tobacco leaves and 800 g of petroleum ether, reflux extraction at 40° C. for 2 h under 50 kHz ultrasonic treatment, the ultrasonic power is 120 W, and separate the filtrate and filter residue.
[0037] The filtrate was concentrated until 36.5 g of a concentrate was obtained.
[0038] In terms of weight ratio, weigh 10:1, 5:1, 1:1, 1:5, 1:10, 1:20, 1:30, 1:50 petroleum ether and ethyl acetate mixture as eluent , 500mL for each gradient. The concentrate was loaded onto a silica gel column, and the gradient elution was carried out. The receiving solution was numbered and marked according to the order of outflow, and a total of 265 tubes of receiving solution were obtained, each tube was 15ml, and they were numbered sequentially. Take the combined liquid from tubes 165-228 and concentrate at 45°C under a pressure of 0.08MPa to remove the solvent to obtain the aromatizer.
[0039] Dilute the aromatizer obtained with ethanol with...
