A chemical investigation by headspace SPME and GC–MS of volatile and semi-volatile terpenes in various olibanum samples

Separation of Odor Constituents by Microscale Fractional Bulb-To-Bulb Distillation

“…Frankincense has been used as a valuable fragrance source since ancient times, and has been reported to possess a wide range of bioactivity. Many compounds have been identified in frankincense (Hamm et al, 2005;Mertens et al, 2009). To our knowledge, however, the effects of particular odor components have not been clarified in detail.…”

Volatile Compounds in Oleo-gum Resin of Socotran Species of Burseraceae

“…massfinder.com/wiki/Terpenoids_Library_List 2015; www.pherobase.com/database/kovats-index. php 2015; Camarda, et al, 2007;Hamm, et al, 2005;Hamm, et al, 2003). The relative amount of each detected compound was calculated as the ratio of the individual peak area to the sum of areas of all peaks in the chromatogram expressed as area percentage.…”

“…Thus, although there have been a number of studies (Bekana, et al, 2014;Hussain, et al, 2013;Al-Saidi, et al, 2012;Assefa, et al, 2012;Paul, et al, 2012;Shen, et al, 2012;Woolley, et al, 2012;Mothana, 2011;Mothana, et al, 2011;Sun, et al, 2011;Li, et al, 2010;Van Vuuren, et al, 2010;Mertens, et al, 2009;Al-Harrasi, et al, 2008;Shen, et al, 2008;Camarda, et al, 2007;Singh, et al, 2007;Frank, et al, 2006;Kubmarawa, et al, 2006;Marongiu, et al, 2006;Basar, 2005;Hamm, et al, 2005;Mathe, et al, 2004;Badria, et al, 2003;Baser, et al, 2003;Hammet, et al, 2003;Mikhaeil, et al, 2003;Dekebo, et al, 2002e;Kasali, et al, 2002;Dekebo, et al, 1999;Verghese, et al, 1987;Strappaghetti, et al, 1982) on commercially important species (Boswellia sacra/ carterii, B. papyrifera, B. serrata, B. frereana, B. neglecta, B. rivae, B. dalzielli), we have practically zero knowledge about the chemical composition of resin of species that have small geographical distributions, including various endemic species. For example, only one study of Boswellia pirottae, a species endemic to Ethiopia (Baser, et al, 2003), has been published as has only one study of three endemic species (B. elongata, B. socotrana and B. disoscorides) from Socotra Island .…”

Ancient Egyptian herbal wines

“…The goal was to discover whether the Egyptian wines contained any plant additives, which had been implied by our earlier analyses. Headspace SPME and TD GC/MS have great utility in biomolecular archaeology because of their high sensitivity and selectivity for volatile compounds of interest (8,21). SPME extraction efficiency and sensitivity are considerably increased by dissolving or suspending the solid sample in an aqueous saline solution.…”
