PRODUCTION OF ESSENTIAL OIL AND CONCRET IN VARIOUS TYPES OF TOBACCO (NICOTIANA TABACUM L.)
Lenka Cvetanovska*, Ana Cvetanovska and Marija Krstikj
The essential oils in tobacco are used as a key ingredient for keeping the taste and aroma. The pleasant smell in tobacco leafs comes from the essential oils and polyphenols. The positive correlation between the production of essential oil and its distribution in different leaf area in different varieties, clearly speaks for the linear dependence of the development phase and increased production of the essential oil going from the lower to the upper leaf area. Lowest values are obtained from the lower leaf area in all examined types, but they are insignificantly different. There are insignificant variations in terms of the intensity of the synthesis of essential oil in different harvests in all types. This proportionality is in correlation with the material’s oldness, adequate weather conditions and the way of collecting plant material. Concret and absolute are used in perfumery industry. Also they are used in the pharmaceutical industry as an aromatic residue with waxy texture (after the extraction of the essential oil). The analyses for percentage of concret in the examined tobacco types are made from this aspect, regarding to their leaf areas during the two cycles.
