The genus Boswellia comprises many species which are famous for their production of frankincense, a fragrant gum resin. In the published literature, manifold studies on the volatiles and semivolatiles in individual samples of these gum resins exist, yet very few studies have investigated multiple samples. Contradictory results with regard to the volatile composition exist in literature. In this first part of the study, a large sample set (n = 46) of mostly commercially obtained gum resins and essential oils was investigated by solid-phase microextraction gas chromatography/mass spectrometry. A total of 216 compounds were identified or tentatively identified from the four commercially relevant species, namely B. sacra, B. serrata, B. papyrifera, and B. frereana, and the statistical evaluation of the resulting chemical profiles allowed a clear distinction between the species by their volatile profile. With only few exceptions, the designated species was found to be in accordance with the composition reported in reliable literature sources and detected in botanically identified samples. Chemotaxonomic marker substances were suggested to facilitate the differentiation of commercial gum resins or essential oils based on their volatile profile.

“…Table 1 summarizes the relevant information on the samples. All analytes were reported in [2] to be odorants in B. sacra gum resin, with two exceptions: cis-carveol was quantified for comparison with the trans-isomer, and α-terpineol was analyzed for its relevance as a fragrance allergen. Additionally, the stable isotope labelled standard of α-terpineol served for the quantification of the carveols.…”

“…The investigated compounds in the group of oxygenated monoterpenes can be further divided into monoterpene alcohols ( 6, 7, 9, 10 ), ketones ( 8,11 ) and a single monoterpene ether, eucalyptol ( 1,8-cineole, 3 ). The latter was observed in amounts of 85-170 mg / kg.…”

“…In general, this fast and convenient method might additionally serve as an alternative to the solid phase micro-extraction ( SPME ) GC-MS approach for the speciation analysis by chemotaxonomic marker substances in Boswellia gum resins [8]. Thereby, it could be beneficial in quality control and fraud detection.…”

“…Hydrodistillation is used to produce an essential oil in about 4-10 % yield. Recently, we have reported potent odorants from B. sacra by an aroma extract dilution analysis approach [2]. The majority of these substances are monoterpenoids, which occur at relatively high levels in the raw material.…”

The (+)‐cis‐ and (+)‐trans‐Olibanic Acids: Key Odorants of Frankincense

et al. 2016

View full text Add to dashboard Cite

Frankincense (olibanum) is one of the oldest aromatic materials used by humans,b ut the key molecular constituents contributing to its characteristic odor remained unknown. Reported herein is the discovery that (1S,2S)-(+ +)-trans-and (1S,2R)-(+ +)-cis-2-octylcyclopropyl-1-carboxylic acids are highly potent and substantive odorants occurring in ppm amounts in all of the frankincense samples analyzed, even those showing radically different volatile compositions. These cyclopropyl-derived acids provide the very characteristic old churchlike endnote of the frankincense odor.
