 [Basar, Simla. "Phytochemical investigations on Boswellia species." Comparative studies on the essential oils, pyrolysates and boswellic acids of Boswellia carterii, 2005, 59]
+Main volatile components of B.frereana resin detected by headspace SPME-GC/MS were α-thujene (11.7%), α-pinene (3.4%), sabinene (3.0%), myrcene (7.0%), p-cymene (4.7%), methyl chavicol (8.9%), and methyl eugenol (3.7%). \\
 "Six different olibanum samples with certified botanical origin were analyzed by headspace SPME–GC/MS in order to define their mono-, sesqui- and diterpenic composition, as pertinent criteria of identification. Boswellia carteri and Boswellia sacra olibanum have quite similar chemical composition, with isoincensole acetate (isoincensole and isoincensole acetate together 6.9%) as the main diterpenic biomarker. Although Boswellia serrata olibanum also exhibits this biomarker, the presence of methylchavicol, methyleugenol and an unidentified oxygenated sesquiterpene distinguishes B. serrata olibanum from the two other species." \\

 "The chemical composition of Boswellia carteri (Somalia), B. papyrifera (Ethiopia), B. serrata (India) and B. rivae (Ethiopia) oleogum resin essential oils was investigated using GC-MS to identify chemotaxonomy marker components... B. carteri and B. serrata oleogum resin oils showed similar chemical profiles, with isoincensole and isoincensole acetate as the main diterpenic components." \\

+"α-Thujene (C) and α-Pinene (D): This is the most obvious key to determining whether a Boswellia oil is a serrata, or another. Indeed, serrata frankincense monoterpenic fraction is vastly dominated by α-thujene, whereas α-pinene is much more important in other species. We usually detect α-thujene in the 55-75% range for B. serrata." \\
