• Resumen

  • The essential oil of Marchantia convoluta was obtained by supercritical fluid extraction (SFE) using methanol as a modifier. The effects of different parameters, such as pressure, temperature, modifier volume and extraction time, on the extraction of essential oil from M. convoluta were investigated. Maximum global yields were obtained using the following conditions: extraction temperature, 40 ºC; dynamic time, 40 min; pressure, 15 Mpa and modifier volume, 35 ml. The essential oil extracts were analyzed by capillary gas chromatography with mass spectrometric detector (GC-MS). The obtained results were compared with references
