Chemical composition and enantiomeric distribution of monoterpenoids of the essential oil of Abies spectabilis from Nepal
AUTHOR(S): Prabodh Satyal and William N Setzer
ABSTRACT:Two subspecies of Abies spectabilis, A. spectabilis subsp. densa and A. spectabilis subsp. langtangensis, were collected from Dhankuta (eastern Himalaya) and Jumla (western Himalaya) of Nepal, respectively. The leaf (needle) essential oils were obtained by hydrodistillation and analyzed by gas chromatography – mass spectrometry as well as chiral gas chromatography. The major components in the essential oil of A. s. densa were limonene (26.9%, 99% (–)-enantiomer), α-pinene (22.2%, 90% (–)-enantiomer), bornyl acetate (10.3%, 100% (–)-enantiomer, β-phellandrene (9.7%, 99% (–)-enantiomer), camphene (7.1%, 100% (+)-enantiomer), and β-pinene (6.5%, 96% (–)-enantiomer). A. s. langtangensis was composed largely of α-pinene (33.4%, 75% (+)-enantiomer), bornyl acetate (10.9%, 100% (–)-enantiomer), selin-11-en-4β-ol (9.4%), and α-bisabolol (4.0%)
