 "More than 100 constituents of the commercial topped Brazilian Vassoura oil (ex Baccharis dracunculifolia DC.) were identified by GC-MS and 1H-NMR spectra. The oil is composed of c. 19% of monoterpene hydrocarbons, c. 2% of oxygenated monoterpenes, c. 38% of sesquiterpene hydrocarbons, and c. 35% of oxygenated sesquiterpenes (15% nerolidol). The trace constituents (E)- and (Z)-4,8-dimethylnona-3,7-dien-2-one, the vitispiranes, the theaspiranes, β-damascone, β-damascenone, the cabreuva oxides, β-ionone, and some 3-phenyl propanoates are olfactorily valuable." \\ "More than 100 constituents of the commercial topped Brazilian Vassoura oil (ex Baccharis dracunculifolia DC.) were identified by GC-MS and 1H-NMR spectra.

 "Baccharis dracunculifolia, “Vassoura”, is a shrub with spontaneous occurrence in Brazil, Uruguay, Argentina, Paraguay, and Bolivia. The Vassoura oil, valuable in the perfumery industry for its exotic aroma, presents variations in composition depending on the geographical origin and extraction process. The commercial importance is related to the oxygenated fraction content, specifically to (E)-nerolidol and spathulenol... \\ "Baccharis dracunculifolia, “Vassoura”, is a shrub with spontaneous occurrence in Brazil, Uruguay, Argentina, Paraguay, and Bolivia.
