Two never - before - seen molecules are responsible for the " old church building " scent of frankincense , one of the gifts given to baby Jesus and a well - known incense " look . "
investigator distilled the scent - creating molecules of theancient perfumeto find the two new compounds , now dub olibanic acid .
Scientists have figured out what gives Frankincense its churchy scent.
" They are bear in extremely low amount " — less than 100 section per million in the essential oil for the most potent atom , study drawing card Nicolas Baldovini , a chemist at the Institute de Chimie de Nice in France , wrote in an email to Live Science . " Therefore , their isolation is very difficult . "
Mystery molecules
Frankincensemay well be the erstwhile perfume used by humans , Baldovini said . The scent come up from the resin of gum tree of the genusBoswellia , and it was cauterise as incense in ancient Mesopotamia and Egypt . The old archaeological evidence for gum olibanum use dates back to the late fourth millenary B.C. Frankincense is also mentioned repeatedly in the Bible : TheQueen of Shebabrings it to King Solomon , and the three Magi gift some of it to babe Jesus .

" As for many natural aromatic raw materials , the nature of its key odorants was still poorly see , " Baldovini said , adding that he had personal reasons to want to study gum olibanum . " I really love its odor , " he said .
Baldovini and his colleagues painstakingly break down the all-important oil colour of frankincense into its constituent parts through a multistep process of extraction and distillate . They used human sniff examiner to check which fraction of frankincense were responsible for its smell .
Synthesized frankincense
In this process , the researcher identified a particularly interesting " odor zone " that smell of the " distinctive balsamy , old church - similar endnote of gum olibanum , " theywrote online Oct. 4 in the journal Angewandte Chemie : International Edition . Further analysis unwrap the relevant molecules to be one ( + ) -trans- and one ( + ) -cis-2- octylcyclopropyl-1 - carboxylic acid . In chemical science , " trans " and " Commonwealth of Independent States " indicate a mirror - image molecule . The social organization is the same in each , but they are arranged in opposite directions .
It was a bit surprising to rule that previously unknown molecules explain frankincense ’s classifiable smell , Baldovini said . He and his fellow worker were able to synthesize synthetic versions of the molecules , which could be used by the perfume industry .
" We patent the use of these chemical compound for sweetness formulation , " Baldovini say .
