ABSTRACT The main objective of this study was to determine the chemical composition of both turpintine and colophony parts of Abies cilicica subsp. isaurica (Taurus fir) oleoresin collected from Mersin-Turkey. Colophony of taurus fir was not performed before. Hydro-distillation was applied for the separation of turpentine and colophony. Samples were analyzed separately by FID-GC and GC-MS. The yield of oleoresin was 14,3 % turpentine and 82,5 % colophony. Fourty-six compounds were found in the turpentine where α-pinene (81,2 %) was the major compound with β-pinene (12,6 %). However, in the colophony abietane type resin acids were forming the main group (abietic 46,8%, neoabietic 29,5%). Resin hydrocarbons and terpenes were identified in the unsaponified fraction of colophony of Taurus fir. High α-pinene and abietic acid contents make this oleoresin to be used in pharmacy and chemical industries. RESUMO O objetivo principal deste estudo foi determinar a composição química das partes de turpintina e colofonia de Abies cilicica subsp. oleasina de isaurica (Taurus fir) coletada de Mersin-Turkey. A colofonia de taurus fir não foi realizada antes. Utilizou-se hidro-destilação para a separação da terebentina e da colofonia. As amostras foram analisadas separadamente pelo FID-GC e GC-MS. O rendimento de oleorresina foi de 14,3% de trepentina e 82,5% de colofonia. Quarenta e seis compostos foram encontrados na terebintina onde o α-pineno (81,2%) foi o principal composto com β-pineno (12,6%). No entanto, na resina de colifonia, os ácidos de resina formaram o grupo principal (abietic 46%, neoabietic 29,5%). Os hidrocarbonetos de resina e os terpenos foram identificados na fração não apontada da colofonia do abeto Taurus. Os altos níveis de α-pineno e ácido abítico tornam esta oleorresina a ser utilizada em farmácias e indústrias químicas.
