The extracts obtained by each extraction method were submitted to the solvent elimination in a rotary evaporator (Fisatom, 802, Brazil), supplied with cooling and vacuum control. The evaporation temperatures were adjusted to a level below the boiling point of the solvent in order to avoid thermal degradation of the extracts. The vacuum was adjusted at 650 mmHg. The global yield (X0) for all method of extraction was obtained by the mean value from the duplicate experiments considering the ratio between mass of extract and mass of raw material.
