 "The main odour-potent odorants detected by GC-O in the diethyl ether extracts were monoterpenoids, such as α-terpineol, carvone, mintlactone, isomintlactone, and sesquiterpenoids such as 6,10-epoxy-7(14)-isodaucan, juneol, 10-epi-γ-eudesmol, and kusunol. These compounds contribute to the woody, herbal and minty characteristic odour of extracts from B.graveolens." \\ "The main odour-potent odorants detected by GC-O in the diethyl ether extracts were monoterpenoids, such as α-terpineol, carvone, mintlactone, isomintlactone, and sesquiterpenoids such as 6,10-epoxy-7(14)-isodaucan, juneol, 10-epi-γ-eudesmol, and kusunol.

 In the roast aroma extract (dry distillation of wood), compounds with strong smoky-phenolic odour like furfural, guaiacol, phenol, p-cresol and 4-vinylguaiacol were detected together with the sweet smelling compounds cyclotene (caramel-like), 3,3-dimethyl-2(3H)-benzofuranone (sugar-like), and vanillin. "The mintlactones, such as 2,3-didehydromintlactone, mintlactone, and isomintlactone, have a herbaceous minty characteristic odour." \\ In the roast aroma extract (dry distillation of wood), compounds with strong smoky-phenolic odour like furfural, guaiacol, phenol, p-cresol and 4-vinylguaiacol were detected together with the sweet smelling compounds cyclotene (caramel-like), 3,3-dimethyl-2(3H)-benzofuranone (sugar-like), and vanillin.
