Title : EXTRACTION OF CLOVE USING PRESSURIZED HOT WATER
Abstract : Sub critical water extraction was used to extract eugenol and eugenyl acetate from clove at various temperatures and pressures where water was in either the liquid or gas (steam) phase. Several solid phase materials were tested in order to quantitatively and selectively collect the analytes after the water extraction. The extraction kinetics with sub critical water was very fast at high temperatures, giving a 100 percent recovery after 15 min for eugenol and eugenyl acetate. Both eugenol and eugenyl acetate were found to be stable at the highest extraction temperature.
