Title :  A COMPARATIVE STUDY ON THE HYPOLIPIDEMIC ACTIVITY OF ELLEVEN DIFFERENT PECTINS
Abstract :      Inclusion  of  pectin-rich  fruits  and  vegetables  can  be regarded   as  one  of  the  primary  prevention  strategies   of hyperlipidemia.  But, it has been found that all pectins  do  not show  effective  hypolipidemic  activity.  Eleven  pectins   were screened  among which pectins from Carica papaya, (ERANDA KARKATI) Coccinia indica (Bimbi), Lycopersicum esculentum (Tamatur)  and cumns sativus (Trapusa) showed highly significant  hypolipidemic activity in albino rats, while  others were less significant or insignificant in their action.  Detailed studies on elucidating the mechanism of action of these  pectins revealed that hypolipidemic activity was mainly due to the  lower rate  of absorption and higher rate of degration and  elimination of  lipids.  The increased activity plasma  Lecithin  Cholesterol Acyl  Transferase activity [LCAT] in rats fed pectin can  account for the significant decrease in the concentration of cholesterol. The  higher activity of lipoprotein lipase in the adipose  tissue and  heart may be responsible for the decreased  concentration  of triglycerides in serum of rats fed pectin.

GERMINATED BARLEY FOODSTUFF IMPROVES CONSTIPATION INDUCED BY LOPERAMIDE IN RATS.

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...
