Boswellia sacra Essential Oil Profiles

Chemical profiles for Boswellia sacra essential oils obtained from different temperatures of hydrodistillation demonstrated that α-pinene is the major compound present in both temperatures preparations (Additional File 1, Table S1). Contents of α-pinene decreased with higher temperature distillation. In addition, essential oils from both temperatures preparations were primarily composed of the major monterpene, including α-thujene, unidentified 1, β-pinene, and myrcene. In general, all compounds with higher retention indices, with a few exceptions, were present in higher quantities in essential oil distillated at 100 ^oC as compared to that obtained at 78 ^oC.
