Determination of Tocopherols and Fatty Acids in Seeds of
Background: The dried fruits of Silybum marianum (L.) Gaertn (Compositae) contain silymarin, an isomeric mixture of flavonolignans. Silymarin acts as a strong anti -hepatotoxic. This fruits contains a high amount of oil . Objective: The objective of this study was to determine total lipid content, fatty acid composition and content of different kind of tocopherols in seed oils of S. marianum...
متن کاملEffects of a bacterial probiotic on ruminal pH and volatile fatty acids during subacute ruminal acidosis (SARA) in cattle
Effects of a bacterial probiotic (BP) on ruminal fermentation and plasma metabolites were evaluated in four Holstein cattle (body weight, 645 ± 62 kg; mean ± SD) with induced subacute ruminal acidosis (SARA). SARA was induced by feeding a SARA-inducing diet, and thereafter, 20, 50 or 100 g per head of a commercial BP was administered for 7 consecutive days during the morning feeding. Cattle wit...
متن کاملThe relationship in the cow between milk-fat secretion and ruminal volatile fatty acids.
I . The effect of reducing the hay and of increasing the proportions of concentrate and flaked maize in the diet of cows on the secretion of milk fat and its component fatty acids and on the proportions of volatile fatty acids in the rumen liquor has been studied. 2. The low-hay diet caused a fall in the milk fat content to about half of the values in the initial control period and the secretio...
متن کاملThe Absorption of Soluble, Volatile Fatty Acids*
Experimental investigations show clearly that the absorption and metabolism of the short chain, water-soluble fatty acids differ in some way from those of the long chain fatty acids insoluble in water. Experiments by Lebedeff (1883), Leube (1895), Zunts (1901), and Eckstein (1929) show no evidence of the butyryl radical in the deposited fat when fed either as a fat or in the form of tributyrin....
متن کاملIsomers of conjugated linoleic acids are synthesized via different mechanisms in ruminal digesta and bacteria.
Digesta samples from the ovine rumen and pure ruminal bacteria were incubated with linoleic acid (LA) in deuterium oxide-containing buffer to investigate the mechanisms of the formation of conjugated linoleic acids (CLAs). Rumenic acid (RA; cis-9,trans-11-18:2), trans-9,trans-11-18:2, and trans-10,cis-12-18:2 were the major CLA intermediates formed from LA in ruminal digesta, with traces of tra...
