Boswellia papyrifera

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 oleogum resin also contained nortriterpenes (24-noroleana-3,12-diene and 24-norursa-3,12-diene) and α-boswellic acid.
