GC-MS analysis of volatile compounds of frankincense from Boswellia papyrifera in Northern Ethiopia

Abstract

A study was conducted to evaluate the effects of the two study sites on essential oil content (EOC) and essential oil composition (EOCP) of the oleo-gum resins obtained from Boswellia papyrifera. Authentic representative oleogum resin samples were collected from Abergelle and Metema in the northern dry land aria of Ethiopia. The essential oils were obtained by hydro distillation using in a Clevenger-type apparatus for 3h and the average oil content 1.09% in Metema and 0.25% in Abergelle were recorded. The volatile oil of Boswellia papyrifera was examined by GC and GC-MS techniques and ten components (85.68%) comprising 100% of total volume in Abergelle and fifteen components (86.12%) comprising 100% of total volumes in Metema were identified. Acetic acid (58.56%, 51.23%, 1-octanol (8.87%, 17.66%) and Ethyl-3-en-1-yl (12.91%, 11.72%) were found to be the major components in the study species which were collected Abergelle and Metema. In this paper we found the results of our study on the volatile oils of olio-gum resins collected from the two sites were observed that the GC-MS spectrum of the oil have similar but the essential oil content have significant difference.
