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.

Author(s) :  . (Applied Bioresearch Center, Corporate Research and Development Division Kirin Brewery Company Limited, Miyaharacho 3, Takasaki, Gunma  370-1295, Japan), Address :  Kannuchi,0.; Hitomi, Y.; Agata, K.; Nakamura, T.; Fushiki, T Source :   Bioscience, Biotechnology and Biochemistry, v. 62(9): p. 1788-1790, 1998 Title :  GERMINATED BARLEY FOODSTUFF IMPROVES CONSTIPATION INDUCED BY LOPERAMIDE IN RATS. Abstract :      The effects of germinated barley (YAVA) foodstuff (GBF) derived from the aleurone and scutellum fractions of germinated barley low-lignified hemicellulose were examined in Sprague-Dawley rats with constipation induced by Loperamide by addition to the diet (2 mg/kg body weight). Bowel movements were higher in the GBF-fed rats than in the cellulose-fed rats used as control. Fecal water content was also higher in the GBF-fed rats. The concentration of short chain fatty acids in cecal content, especially butyrate, was signi...
