The Baccharis genus presents great diversity of essential oils. The chemical composition has been studied due the economic importance for the fragrance and flavoring industries. This study aimed to evaluate the essential oil yield and composition of 10 species of Baccharis of Araucaria Forest, Piraquara - PR. Essential oil samples from fresh leaves of Baccharis articulata Pers., B. trimera (Less) DC., B. milleflora DC., B. oblongifolia Pers., B. anomala DC., B. calvescens DC., B. uncinella DC., B. axillaris DC., B. mesoneura DC., and B. myriocephala DC were obtained by hydrodistillation in a Clevenger apparatus during 4.5 hours. The chemical constituents were analyzed by GC-MS. In both analyzes fused silica capillary column was applied, HP-5MS (30 m x 0.25 mm x 0.25 µm), using helium as the carrier gas (1.0 mL min-1) at a temperature of 120 °C. The oven temperature ranged from 60 °C to 240 °C at a heating rate of 3 °C min-1. Identification of essential oil component was done by comparison of both mass spectra and retention indices values with compounds described in the stored data and literature (1,2). The essential oil content of B. articulata, B. trimera, B. milleflora, B. oblongifolia, B. anomala, B. calvescens, B. uncinella, B. axillaris, B. mesoneura e B. myriocephala were 0.07; 0.76; 0.90; 0.69; 0.72; 0.70; 1.89; 0.03; 0.97; e 0.02%, respectively. It were identified 32 constituents (90.1 %) in the essential samples of B.articulata, 30 (91.9 %) in B. milleflora, 20 (96.2 %) in B. oblongifolia, 24 (81.3 %) in B. anomala, 29 (96.0 %) in B. calvescens, 29 (96.7 %) in B. uncinella, 23 (94.3 %) in B. axillaris, 25 (70.3 %) in B. trimera, 23 (82.0 %) in B. mesoneura and 28 (91.6 %) in B. myriocephala. The major constituents of B. articulata were limonene (38.4 %) and β-pinene (30.2 %); of B. trimera carquejila acetate (52.7%) and limonene (18.6 %); of B. milleflora viridiflorol (24.1 %) and limonene (22.6 %); of B. oblongifolia limonene (32.7 %) and germacrene D (6.3 %); of B. anomala limonene (23.9 %), germacrene D (19.7 %) and δ-cadineno (8.0 %); of B. calvescens limonene (39.5%) and β-pinene (13.7 %); of B. uncinella limonene (24.1 %) and spathulenol (17.2 %); of B. axillaris α-pinene (41.9 %) and limonene (31.9%); of B. mesoneura limonene (32.2 %), α-pinene (15.5 %) and α-thujene (14.4 %); of B. myriocephala limonene (41.9 %) and β-pinene (16.7 %).  1.
