On the basis of gas-chromatographic and mass-spectroscopic analysis differences in the content of three main fractions (weakly acid, neutral, basic) in condensate (CSC) of pure Burley and Burley treated with four fruit concentrates as additives were estimated. The components of weakly acid and neutral fractions were identified. In WacF, 16 components common to all the samples and 7 specific compounds were identified. In NF, 19 compounds were identified as common to all the samples and 9 identified components (for ex: geraniol and trans-fernesol) were specific.
