Application of pattern recognition method for color assessment of oriental tobacco based on HPLC of polyphenols DAGNON S.; EDREVA A. Inst. for Tobacco and Tobacco Products, Plovdiv, Bulgaria The color of Oriental tobaccos was organoleptically assayed, and high performance liquid chromatography (HPLC) of polyphenols was performed. The major tobacco polyphenols (chlorogenic acid, its isomers, and rutin), as well as scopoletin and...
CORESTA Meeting, Agronomy/Phytopathology, Bucharest, 2003, AP 10 Contribution of valeric acids to aroma characteristics of Oriental tobaccos DAGNON S.; TACHEVA R.; STOILOVA A.; EDREVA A.; CHRISTEVA D. Inst. for Tobacco and Tobacco Products, Plovdiv, Bulgaria Levels of free valeric acids (isovaleric and 3-methyl valeric) in leaves of different tobacco types were quantified by using CGC (capillary gas chromatography) equipped with flame ionization detector. Their content in tobacco smoke was also...
