Three new eudesmane sesquiterpenoids, commiphoranes E1-E3 (1-3), a new podocarpane diterpenoid, commiphorane F (4), three new triterpenoids, commiphoranes G1-G3 (5-7), and fourteen known terpenoids (8-21) were isolated from Resina Commiphora. The structures and relative configurations of new compounds were mainly assigned by spectroscopic methods. In particular, the absolute configuration of 3 was clarified by computational methods. Renoprotective effects of all these isolates were evaluated by using an ELISA assay in TGF-β1-induced rat kidney tubular epithelial cells. The present findings add new facets for chemical profiling of plant resins.

Article Synopsis
- Burseraceae resins, derived from specific plant species in Brazil, are highly valued for their diverse medicinal uses across the country, yet their cultural significance remains underexplored.
- This review aims to gather existing ethnomedicinal, chemical, and pharmacological data on these resins to highlight their therapeutic potential.
- At least 21 plant species from the Burseraceae family are identified for their medicinal resins, mainly used to treat headaches and wounds, with promising pharmacological evidence supporting these uses, though more research is needed to validate their effectiveness.
