Essential oil from aerial parts of Artemisia vulgaris L., was obtained by hydro-distillation to produce oil in the yield of 0.25% (w/w). The oil was analyzed by capillary gas chromatography, using mass spectrometric detection. The amount of the samples injected by nano scale included were 1.0 nL (diluted 1.0 μL of sample in 1000 ml of n-pentane, v/v). Twenty three bioactive and flavour molecule...
