Chemical Composition and Antimicrobial Activity of Some Oleogum Resin Essential Oils from Boswellia SPP. (Burseraceae)

Abstract

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. Total ion current peak areas gave good approximations to relative concentrations based on GC-MS peak areas. B. carteri and B. serrata oleogum resin oils showed similar chemical profiles, with isoincensole and isoincensole acetate as the main diterpenic components. Both n-octanol and n-octyl acetate, along with the diterpenic components incensole and incensole acetate, were the characteristic compounds of B. papyrifera oleogum resin oil. Hydrocarbon and oxygenated monoterpenes were the most abundant classes of compounds identified in the B. rivae oleogum resin oil. The antimicrobial activities of the essential oils were individually evaluated against different microorganisms including fungi, Gram-positive and Gram-negative bacteria strains. The essential oils with the best activity against fungal strains were those obtained from B. carteri and B. papyrifera with MIC values as low as 6.20 microg/ml. The essential oil of B. rivae resin showed the best activity against C. albicans with a MIC value of 2.65 microg/ml.

The volatile constituents of frankincense – a review

“…Analysing B. serrata by hydrodistillation, Singh, [18] Verghese [19] and Camarda [20] all found a-thujene to be the dominant substance. However, specifi c values were in the range 22.7-61.4%.…”

“…Altogether, 12 common volatiles were found in all B. carteri samples: Bornyl acetate, camphene, cembrene A, p-cymene, [18] Verghese (1987) [19] Basar (2005) [8] Camarda (2007) [20] limonene, myrcene, a-pinene, b-pinene, trans-pinocarveol, sabinene, a-terpineol and verticilla-4(29),7,11-triene. The substances found in B. serrata samples agreed in most cases.…”

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 .…”

Effect of Olibanum (Boswellia thurifera) as a feed additive on performance, some blood biochemical and intestinal morphology in broiler chicks

“…It contains mono (13%) and diterpenes (40%) as well as ethyl acetate (21.4%), octyl acetate (13.4%), and methylanisole (7.6%). The main biological activity *Corresponding author: Sayeed Nouroldin Tabatabaie, Department of Animal Science, Islamic Azad University, Isfahan (Khorasgan) branch, Isfahan, Iran among terpenes is attributed to 11-keto-ß-acetyl-betaboswellic acid, acetyl-11-keto-ß-boswellic acid and acetyl-α-boswellic acid (Camarda et al, 2007). Singh et al (2007) found that a dose of the pure Boswellia serrata at the level of 500 mg/kg of body weight was sufficient to inhibit their growth.…”
