-"The resin produced by this species is called “lobãn majdi” or commonly “maydi”. It is the most expensive brand of olibanum on the market... The hydrodistillate of B.frereana determined in this work was light yellow in color. The investigation of the essential oil by GC... and GC-MS indicated that the oil was predominantly composed of α-thujene (8.1%), α-pinene (38%), p-cymene (11%), limonene (2.4%), sabinene (2.6%), trans-verbenol (4.2%) and bornylacetate (2.8%). As diterpenoic constituents, isomers of α-phellandrene dimers were observed. They were recognized as the diagnostic markers of B.frereana." \\+"The resin produced by this species is called “lobãn majdi” or commonly “maydi”.
