This is the first time that composition, antimicrobial potential and antioxidant ability of essential oil from the leaves of Baccharis oreophila are reported. Essential oil was obtained by hydrodistillation and analyzed by GC/MS. Antimicrobial potential was evaluated by diffusion disk and broth microdilution methods. ABTS * + , DPPH * and FRAP methods were employed for antioxidant activity evaluation. Essential oil yield was 0.47 %. Sixty-five compounds were identified, representing 88.53 % of the total essential oil, which showed to be rich in oxygenated (37.88 %) and hydrocarbons sesquiterpenes (34.84 %). The main constituents were khusimone (16.37 %) and spathulenol (16.12 %). Antimicrobial activity was verified against S. aureus (10.33 � 0.5 mm, MIC: 1250 μg mL À 1 ) and C. albicans (8.66 � 0.5 mm, MIC: > 2500 μg mL *1 ). Antioxidant ability was evidenced by FRAP (4.09 μmol FeSO 4 E mL À 1 ), ABTS * + (1.45 μmol TE mL À 1 ) and DPPH * (1.04 μmol TE mL À 1 ) scavenging capacity. Results showed that this essential oil has interesting biological potential, encouraging further investigations especially in relation to action mechanisms of antimicrobial and antioxidant activity.

“…Aqueous and ethanolic extracts (10%; v/v) were centrifuged (2,500 g; 20 min) and the supernatants were used for quantification of phenolic compounds. The colorimetric analysis was done as per Sartor et al (49). Briefly, 100 µL extract was mixed with 2.5 mL Folin-Ciocalteu reagent and 0.7 M Na 2 CO 3 .…”

“…Identification and quantification of the allelopathic related-phenolic compounds present in aqueous and ethanolic extracts from Baccharis spp. were done by High Liquid Performance Chromatography (HPLC), as per Sartor et al (49) with modifications. Briefly, analyses were carried out in the system Sikam Chromatography TM S 600, chromatograph operated at 40 ºC, and separations were performed on a MetaSil ODS column (5 µm; 250 x 4.6 mm).…”

“…The genus Baccharis contains the large quantity of various secondary metabolites (1). The phytochemistry of Baccharis genus has shown the presence of diterpenoids, phenolic compounds and essential oils as the major classes of secondary metabolites (1,49,51,58). These compounds may play a role in the composition and dynamics of plant communities, facilitating competition between species, through allelopathy (6,34,55).…”

Merrill] View project ABSTRACTWe evaluated the effects of aqueous and ethanolic extracts from 3-Baccharis species (B. dentata, B. uncinella and B. anomala) on the germination and seedlings growth of Lactuca sativa (model species) and Bidens pilosa (weed), and by chemical analysis, the phenolic compounds were determined in extracts. Aqueous and ethanolic extracts of B. dentata, B. uncinella and B. anomala were tested at 2.5, 5, 7.5 and 10% concentrations. Allelopathic effects of three Baccharis species were variable. The B. pilosa was more sensitive to the extracts than L. sativa and germination was inhibited with ethanolic extracts of B. anomala and B. uncinella from 5 to 10%. Aqueous extract of B. dentata and B. uncinella at 10% concentration reduced the germination of B. pilosa by 80%. The ethanolic extracts of B. uncinella (2.5 to 10%) and B. anomala (5 to 10%) caused 100% mortality of seedlings. Total phenolic compounds were more abundant in aqueous extracts. Amongst the phenolics, catechin was most abundant (1.61 to 6.16 mg g -1 DM) in aqueous and ethanolic extracts of Baccharis species tested. This study showed that Baccharis uncinella may be used as an alternative bioherbicide to control the weeds in agroecosystems.
