Influence of Dried-grass Silage and Silage Fractions on the Basal Metabolic Rate of Rats

Structural determination of two basal metabolic rate-stimulating flavones from grass silage

“…tricin and probably 5,7-dihydroxy-3',4',5'-tri- McLaren et al (1964) have shown that dried grass silage (DGS), made from approximately equal parts of wheat, vetch, orchard grass, and alfalfa, stimulated basal metabolic rates (BMR) when fed to male rats. The basal metabolic rate-stimushown to be basal metabolic rate-stimulating lating activity of these compounds is greater than when fed to male rats, were shown by ultraviolet certain other flavonoids, probably because they spectral analysis and paper chromatography to be are resistant to degradation by intestinal flora.…”

More recently (Qasim, 1970), DGS was extracted according to the method of McLaren et al (1964) and subjected to extensive fractionation with solvent extractions and paper chromatography. McLaren et al (1964McLaren et al ( , 1966 also demonstrated that an 80% ethanol extract of DGS and various other flavonoid-containing extracts were BMR-stimulating to the rat.…”
