Boswellia papyrifera

Chemical constituents

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.
