+Main volatile components of B.frereana resin detected by headspace SPME-GC/MS were α-thujene (9.8%), p-cymene (7.8%), sabinene (3.2%), cis-verbenol (3.5%), verbenone (3.1%), bornylacetate (3.8%) and a dimer of α-phellandrene (15.6%). \\

 The (1S,2S)-(+)-trans- and (1S,2R)-(+)-cis-2-octylcyclopropyl-1-carboxylic acids (olibanic acids) were detected in ppm amounts in acidic extracts obtained from B.frereana. These acids provide the very characteristic old churchlike endnote of the frankincense odor. \\
