摘要：

In this paper, preliminary studies on the chemical characterization of Phthirusa adunca Meyer essential oil, obtained by hydrodistillation, is presented. The separation of the components was performed by GC-MS. Twenty-three compounds (94.5% of the sample) were identified of which the three major ones (76% of the sample) were beta-phellandrene (38.1%), germacrene D (26.8%) and beta-pinene (11.5%). The essential oil showed a broad spectrum of activity against Salmonella Typhi CDC 57 (100 mu g/mL), Staphylococcus aureus ATCC 25923 (200 mu g/mL), Enterococcus faecalis ATCC 29212 (250 mu g/mL), Escherichia coli ATCC 25922 y Klebsiella pneumoniae ATCC 23357 (500 mu g/mL). This is the first report on the composition and activity of the essential oil of this species.
