Chemical Characterization of Lebonan Cedar Tar

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 identifi ed. β-himachalane (22-28 %) was found to be the main compound in all tars. α-himachalane (6-10%) and longifolene (7-9 %) were the other important compounds. Some compounds, which have antifungal and insecticides effects like deodarone and E-(α)-atlantone, were determined only in tars of roots. Phenolic compounds were not determined by the traditional method.U radu je prikazana analiza kemijskog sastava katrana od libanonskog cedra (Cedrus libani A. Rich) dobivenoga tradicionalnim postupkom i uz pomoć Jenknerove retorte. Napravljena je zasebna analiza za staro korijenje i za otpale grane libanonskog cedra. Za kemijsku karakterizaciju primijenjene su metode FID-GC i GC-MS. Prinos katrana uz pomoć Jenknerove retorte bio je 60 %, a prinos tradicionalnom metodom iznosio je 30 – 40 %. Pritom je identificiran 41 kemijski spoj. Ustanovljeno je da je β-himakalan (22 – 28 %) glavni spoj svih analiziranih katrana. Drugi po važnosti bili su A-himakalan (6 – 10 %) i longifolen (7 – 9 %). Neki spojevi koji imaju antifungalne i insekticidne učinke kao što su deodaron i E-(α)-atlanton pronađeni su samo u korijenju. U katranu dobivenom tradicionalnim postupkom nisu pronađeni fenolni spojevi
