Abstract: In order to understand the key volatile aroma components in cigar core tobacco leaves from different producing areas, the volatile aroma components in cigar core tobacco leaves from Indonesia, Brazil, Dominica, Mexico, Hainan and Sichuan were determined by HS-SPME Arrow-GC-MS method, and the main different components were screened by OPLS-DA method. The correlation between them and sensory quality is analyzed. The results showed that there were 124 volatile aroma components in the samples, among which heterocyclic, acid, ketone and ester accounted for more than 84%. The high content compouns included neophydiene, 2,3' -bipyridine, 3-methylvaleric acid, acetic acid, 3-acetylpyridine, dienicotinine, and dihydrokiwi lactone, etc. The total amount of volatile aroma components in different producing areas from high to low was in the order of Indonesia, Hainan, Mexico, Brazil, Dominica and Sichuan. Indonesia had the highest content of aromatic, ketones and esters, Mexico had the highest content of aldehydes and acids, and Hainan had the highest content of aldehydes, alcohols and heterocyclic compounds. A total of 52 different substances were screened from different producing areas, mainly alcohols and heterocyclic compounds. Correlation analysis showed that 9 volatile aroma components were positively correlated with aroma indexes, and 7 of them were closely related to fruit, floral and nut aroma. The results provided a reference for the positioning of tobacco leaf style characteristics.
