Boswellia papyrifera, also known as the Sudanese frankincense,[2] is a species of flowering plant and frankincense that is native to Ethiopia, Eritrea and Sudan. The tree is cultivated in Ethiopia because of its valuable resin. The incense is characterized by a fresh lemon-pine scent[3] and is therefore highly esteemed. In Ethiopia where it is called itan zaf,[4] it comes in semi-translucent yellow tears. The gum resin of Boswellia papyrifera coming from Ethiopia, Sudan and eastern Africa is believed to be the main source of frankincense of antiquity.[5]
In studies conducted on the chemical properties of the oleo-gum resin of B. papyrifera, it was shown to contain a high concentration of octyl acetate (57.1–65.7%) and N-octanol (3.4–8.8%), the former accounting for its citric note. The species also contain diterpenes and nortriterpenes; the methanol extracts specifically consisting of the following diterpenes: incensole, incensyl acetate and verticilla-4(20),7,11-triene). It also contained the following triterpenes: β-amyrin, α-amyrin, β-amyrenone, and α-amyrenone. The oleogum resin also contained nortriterpenes (24-noroleana-3,12-diene and 24-norursa-3,12-diene) and α-boswellic acid.[6]
