Chemical Characterization of Lebonan Cedar Tar

Abstract

Chemical characterization of Cedrus libani A. Rich tar, obtained by the traditional method and Jenkner Retort, was studied. Roots and fallen branches were used and analyzed separately. FID-GC and GC-MS were used for the characterization. The tar yield of Jenkner Retort was 60 %, while it is 30-40 % in the traditional method. 41 compounds were identified. beta-himachalane (22-28 %) was found to be the main compound in all tars. alpha-himachalane (6-10 %) and longifolene (7-9 %) were the other important compounds. Some compounds, which have antifungal and insecticides effects like deodarone and E-(a)-atlantone, were determined only in tars of roots. Phenolic compounds were not determined by the traditional method.
