The essential oil of Marchantia
convoluta was obtained by supercritical (carbon dioxide) extraction
using methanol as a modifier. Global yields were determined according
to the orthogonal design. The effects of different parameters, such
as pressure, temperature, modifier volume and extraction time, on
the supercritical fluid extraction (SFE) of essential oil from M.
convoluta were investigated. Maximum global yields were obtained
using the following conditions: extraction temperature,
