Fig. 2 in Biosynthetic diversity in triterpene cyclization within the Boswellia genus

Fig. 2. Boswellia and their resins. (A) The stem part of the B. sacra tree is tapped to produce a milk-like resin that is dried in the presence of heat and strong wind into a solid form. The collected resin is used for various purposes; however, the tree population is confronted with various types of threats. A detailed understanding is required to ensure the sustainability of the species from this genus. (B) Global distribution map of Boswellia species. (C) A relatively higher abundance of species and endemism have been observed on the island of Socotra, Yemen, whereas intact populations of B. sacra are widely distributed over the Dhofar region of Oman. (D) Variation in resin types and colours from different species of Boswellia.
