-"... 250 components had been identified in olibanum oil or as pyranolysis products of the resin; however, no charcater-impact compound was among these... Olibanum resin contains several odorless cembranoid diterpenes [7.511-7.513 meaning cembrene A, incensol, 1-hydroxycembrene A] and pentycaclic diterpenes, of which yet unidentified pyrolysis products are considered to contribute to the typical odor of incense smoke. Cembrene A was initially identified in pine tree resins, whereas incensol and its 1-hydroxy derivative occur in olibanum only." \\

 Only one synthetic incense odorant, namely 2-methyl undecanoic acid (Mystikal) with its humid resinous incense note, conveys the typical olibanum odor. \\

-Two oxygenated sesquiterpenes, rotundone and mustakone, are potent odorants of frankincense with very low odor thresholds. During GC-O analysis it was observed that close to the threshold level, rotundone imparts a more woody, coniferous, incense-like, and only slightly peppery smell, while at somewhat higher levels the strong, distinct peppery note arises. Mustakone is "...described by panelists as spicy, woody, slightly fatty, meat-broth-like, and balsamic. Interestingly, some panelists remarked that the smell resembles that of α-copaene, which was reported to contribute to the smell of frankincense and smells 'spicy, broth, woody'." \\
