Title :  ISOLATION OF A POTENT MOSQUITO REPELLENT FROM VITEX NEGUNDO L.  AN ALTERNATIVE SOURCE OF ROTUNDIAL
Abstract :      The chloroform fraction of the aqueous extract of the fresh leaves of Vitex negundo (NIRGUNDI) by bio-activity guided isolation yielded a pure compound, Rotundial (C9H1202) which has shown potent mosquito repellent activity. Using spectral data (UV, IR, IH & 13C NMR  and MS) its structure has been elucidated. Rotundial showed 94.1 % repellency up to 4th hour and maintained 82 % at 6th hour at application dose of 0.15 mg/sq. cm.

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...
