【 摘 要 】

The essential oils from the leaves of six speciesof the Baccharis genus (B. dracunculifolia, B. microdonta, B. regnelli,B. schultzii, B. trimera, and B. uncinella), collected in the "Camposde Altitude" of the Atlantic Forest (SP), were extracted using hydrodistillationprocedures and analyzed by GC and GC/MS. There was a predominance of sesquiterpenesin all studied oils as b-elemene in B. dracunculifoliaand B. regnelli, a-humulene in B. trimera,g-gurjunene in B. schultzii, bicyclogermacrenein B. regnelli, d-cadinene in B. regnelliand B. uncinella, spathulenol in B. schultzii, caryophyllene oxidein B. microdonta and guaiol in B. uncinella. However, a high amountof monoterpenes was also observed in B. uncinella (a-pinene),B. regnelli (d-car-3-ene) and B. schultzii(limonene). The chemical compounds of the essential oils of B. schultzii,B. regnelli and B. microdonta are described for the first timein this work.
