[Chemical compositions of the essential oil of commiphora habessinica growing in Yemen: gas chromatography-mass spectrometry analysis]

ABSTRACT

The aim of this study is to analyze the chemical constituents of essential oil of resin of Yemeni Commiphora habessinica. Commiphora. habessinica resin was collected from Hujarriyah district, Taiz Governorate, Yemen. Oleogum resin [20 g] of C. habessinica was subjected to hydrodistillation for 3 h in a Clevenger-type apparatus. The constituents are quantified using Gas Chromatograph equipped with Mass Spectrometry. Thirteen constituents of Yemeni Commiphora habessinica were identified whereas two unidentified compounds with RI 1715 [5.2%], and RI 1819 [4.1%] respectively by Gas Chromatograph equipped with Mass Spectrometry. The major constituents were beta-elemene [32.1%], alpha-selinene [18.9%], cadina-1, 4-diene [7.5%], germacrene B [3.6%], alpha-copaene [3.5%], t-muurolol [3.0%], caryophyllene oxide [2.9%] and alpha-cadinol [2.6%]. The data reported in our study showed that the oil composition of C. habessinica was characterized mainly by sesquiterpene hydrocarbons [69.7%] and showed among the Commiphora oils, the highest percentage in beta-elemene [32.1%] which possessed antitumor activity. Cadina-1, 4-diene, t-muurolol, and alpha-cadinol were identified for the first time in the oil of Cominiphora genus
