摘要

A supercritical extraction of characteristic fragrant substances in different fragrant tobacco leaves, which involves the following steps : 1) cutting the tobacco leaves into shreds and placing the shreds into an extraction vessel with supercritical CO2 fluid; 2) setting the extraction pressure and extraction temperature of supercritical CO2 fluid about 100 to 350 bar and 35 to 70℃, extracting statically the tobacco shreds for 10 to 35 minutes in the condition, then setting the dynamic extracting speed of the supercritical CO2 fluid about 1.0 to 3.5 L/min, and extracting dynamically the tobacco shreds for 5 to 15 minutes; 3)collecting the obtained supercritical CO2 fluid extract, and obtaining the key fragrant substances, which act as the determinants for tobacco fragrance, after completely volatilizing CO2.
