Özet

Fresh and old oleoresin samples from bark and cones of Abies nordmanniana and Picea orientalis were analyzed by gas chromatography and mass spectrometry. The fresh oleoresins from both bark and cones of Caucasian fir were mainly composed of monoterpenes (40.0% and 21.3%, respectively) and resin acids (27,4% and 36.8%). Alpha-Pinene was the dominant constituent of monoterpenes in the bark and cone (21.9% and 17.2%) and abietic acid of the resin acids (11.4% and 19.8%). Pimaric acid, a common resin in softwood resins and oleoresins, was not found in the samples. Sesquiterpenes, resin aldehydes and resin alcohols were minor constituents of the fresh samples. Analysis of the old samples from bark of Caucasian fir presented a completely different composition. The major part of the resin was composed of resin hydrocarbons (34.1%) They were not detected in the fresh samples. The dominant constituent of the old oleoresin was abietadiene (23.0%).
