The essential oil of taurus cedar (Cedrus libani A. rich): Recent results

Abstract

Water and steam distilled essential oils from wood and roots of Taurus Cedar (Cedrus libani A. Rich) obtained from Antalya and Içel (Tarsus) provinces were analyzed by GC and GCIMS. 37 components were characterized representing 90–93% of the oils. Himachalenes (?-, ß-, and ?-) constituted 58.6% of the oils. In order to isolate minor sesquiterpenes, the oils were subjected to fractional distillation and chromatographic techniques. The isolated constituents were characterized by spectral analysis (IR, MS,1H and13C-NMR). Cis- and trans-10,11-dihydroatlantones, cis- and trans-ß-atlantones, 8, 9-dehydroneoisolongifolene, longipinene, ?-ylangene, camphor, sativene, ?-guijunene, longifolene (=junipene), ß-cedrene, ?-calacorene, oxidohimachalene, isohimachalone, nerolidol, longiborneol, cadalene, limonene, and terpinolene were found as constituents of Cedrus libani oil for the first time
