Study on Aroma Component Content and Regular Chemical Composition of Flue-cured Tobacco Leaves and Their Correlation in Lijiang
摘要
Abstract
In order to further clarify the quality characteristics of tobacco leaves of Lijiang , provide theoretical basis for their scientific and reasonable use, aroma materials content of high quality tobacco leaves of the three main cultivars, Yunyan 87 , Yunyan 85 , Yunyan 97, which produced in four counties and one district of Lijiang in 2009 ~ 2010 were analyzed. The results showed: (1) The content of neophytadiene was the highest in 75 species detected aroma materials, being 427. 19 (xg/g, account-ing for 73. 82% ; there were 39 species aldehydes and ketones, being 51. 68 |xg/g, accounting for 8.93% ; 9 species alcohols, being 49.75μg/g, accounting for 8.60% ; 7 species esters and lac-tones, being 15. 58μg/g, accounting for 2. 69% ; 4 species acids, being 21. 77 |xg/g, accounting for 3. 67% ; 3 species phenolics, being 1. 87μg/g, accounting for 0. 32% ; 9 species heterocyclics, being 2. 00μg/g, accounting for 0. 35% ; 3 species aromatic hydrocarbons, being 8. 83μg/g, accounting for 1. 53%. (2) Yunyan 87 had the highest aroma materials content in the three main cultivars, being 638.30μg/g followed by Yunyan 97, was 535.09 |xg/g, the lowest Yunyan 85, was 510.00μg /g. Aroma component content of tobacco leaves in plateau valley was highest, and moist river valley was lowest, being 659. 55μg/g and 533. 25μg/g, respectively, coefficient of variation of these three ecotypes were 0. 20, 0. 18 and 0. 11, respectively. (3) variation rules of aroma materials were not obvious with elevation increased with the range of 500 ~ 650μg/g. (4 ) total sugar and reducing sugar content of tobacco leaves in Lijiang were high, nicotine and potassium content were appropriate , chloride content was low, positive correlations were existed between all kinds of aroma materials , while not obviously associated with the chemical composition.关键词
