Schinus molleis popularly known as aroeira-salsa, with aromaticleaves and branches. The present study wasto evaluate the chemical composition ofthe essential oils fromthe branches and leaves from S. molleand,antifungal activity on the isolate fromSclerotinia sclerotiorum(white mold).The branches and leaves were collected and processed to extractessential oils by hydrodistillation in a Clevenger type apparatus. The yields from essential oils extraction,and their chemical profiles were evaluated by gas chromatography with mass spectrometry.The essential oils yields were 0.21 and 0.37%, with 16 and 21 compounds identified for the essential oils of the branches and leaves, respectively. The major compounds were δ-cadiene 21.77%, viridiflorol 21.74, copaene 12.9% and caryophyllene 9.99% for the essential oil of the branches, for essential oil of the leavesgermacrene D 39.00%, α-pinene 14.77%,and germacrene B 6.25%.The antifungal activity had mycelial inhibition in S. sclerotiorumin allevaluatedconcentrations, with emphasis on 100 μLmL-1,which had inhibition from86.4 and 81.3% for branches and leaves, respectively. The essential oils fromS. mollehad good yields and are rich in monoterpenics and sesquiterpenicscompounds, and have great efficacy inantifungal activity.
