Chemical Composition and Antimicrobial Activity of the Essential oil of Cotinus coggygria Scoop. from Italy

This is the first report about the composition of the essential oil from flowering aerial parts of Cotinus coggygria Scoop. (Anacardiaceae) from Italy. The major compounds identified by GC-MS were limonene (47.1 %), (Z)-β-ocimene (15.2 %), α-pinene (8.5 %) and (E)-β-ocimene (5.3 %). The oil showed antimicrobial activity against three Gram (+) bacteria: Bacillus cereus, Staphylococcus aureus, and S. epidermidis, and three Candida strains: C. albicans, C. glabrata and C. tropicalis, while it was inactive against three Gram (-) bacteria: Pseudomonas aeruginosa, Escherichia coli and Enterobacter cloacae.
