چکیده
Essential oils from different organs of Ageratum fastigiatum (Gardn.) R. M. King et H. Rob., obtained by hydrodistillation were analyzed through Gas Chromatography and Gas Chromatography/Mass Spectrometry. The essential oils were tested for antimicrobial activity by the agar-diffusion method and minimal inhibitory concentration (MIC). The main compounds found were β-caryophyllene, germacrene D and 1,10-di-epi-cubenol. The samples were active against Staphylococcus aureus, Streptococcus mutans, Streptococcus faecalis, Salmonella typhosa, Escherichia coli, but not Pseudomonas aeruginosa and fungi. The MIC ranged from 5.0 to 18.0 mg/mL.

Analgesic and Anti-inflammatory Properties of Essential Oil from Ageratum fastigiatum
The chemical composition, analgesic and anti-inflammatory properties of essential oil from Ageratum fastigiatum were investigated. The main compounds found in the essential oil were germacrene D, α-humulene and β-cedrene. The oil, with LD50 of 2.50 g/kg, inhibited the acetic acid-induced writhing at the dose of 200 mg/kg. In the formalin test, the oil inhibited the first phase (200 mg/kg) and t...
