Gnaphalium uliginosum L. (Asteraceae) is widely used in phytotherapy and has a potential for agricultural utilization. The ethanolic extract was obtained from the maceration of air-dried plants, and the extract was then filtered and concentrated using a rotary evaporator. The essential oil was pressed from freshly harvested and crushed, aerial part of plants. The chemical compositions of ethanolic extract and essential oil of G. uliginosum L. (EOG) were investigated using gas chromatography/mass spectrometry (GC/MS). Nine constituents accounted for 77.3 % of the total detected componentswere determined at the ethanolic extract with a high proportion of sterols 42.8%, fatty acids 24.1 %, triterpenes 14.4 %. Twenty constituents were identified in essential oil of G. uliginosum L.; with α-pinene and estragole accounting for 54.0 %. The ethanolic extract was found to have a moderate antimicrobial activity (MIC values varied from 125 to 500 μg/mL), for S. aureus, B. cereus and A. solani significant activity (less than 62.5 μg/mL). The essential oil was found to have a moderate (MICs 500-1000 μg/mL) and strong activities (31.3-250 μg/mL). The antioxidant activity was evaluated using chemiluminescent assay. The ethanolic extract of G. uliginosum L. acted as a medium-strength antioxidant at concentrations of less than 0.1 mg/mL. The essential oil made be regarded as a weak strength antioxidant.
