comparison of essential oils compositions of boswellia carteri birdwood as a food and non-food in different distillation from iranian market

the genus boswellia is one of the 17 genera belonging to burseraceae family. in this study resin of boswellia carteri birdwoodcollected or purchased from tehram herbal market as a food and non-food for chemical analysis. the essential oils of the resins of boswellia carteri birdwoodobtained by different methods of distillation (water distillation, steam distillation and hydro-steam distillation), the composition of essential oils was analyzed by gas chromatography (gc) and gas chromatography, coupled to mass spectrometry (gc-ms). the major components of the different methods of distillation oils of boswellia carteri birdwood as a non-food by hydro-steam distillation were dihydro citronellol acetate (48%), 2-phenyl ethyl anthranilate (11.5%), α-santonine (7.7%), and with water distillation were dihydro citronellol acetate (48.2%), borneol (8.6%), methyl decanoate (7.9%), and with steam distillation were dihydro citronellol acetate (60.6%), borneol (9.7%), (z)-β-ocimene (5.3%), respectively. also the major components of boswellia carteri birdwood as a food by hydro-steam distillation were dihydro citronellol acetate (55.6%), α-santonine (9%), 2-phenyl ethyl anthranilate (7.3%), and with water distillation were dihydro citronellol acetate (63.7%), borneol (9.1%), 2-phenyl ethyl anthranilate (3%), and with steam distillation were dihydro citronellol acetate (55.9%), (e)-phytol acetate (7.5%), borneol (7.3%), were the predominant major compounds respectively.
