This method described the estimation of different monomers of tannin in serum and cow milk. Animals were supplemented with two types of diets containing 0 and 4 per cent tannin (DM basis) from Acacia nilotica pods. Blood and Milk samples were collected after a preliminary feeding of two and half months and were processed for the estimation of degraded products of babul pods tannin. Phloroglucinol, resorcinol, catechin, epicatechin and catechin gallate were identified and quantified in blood serum sample and the values of various tannin monomers appeared were 128.07.0.17, 2.29, 63.65, and 51.17 ug/dl respectively, while in milk the values were 268.26,2.89, 298.19 and 2.14 ug/dl for phloroglucinol, resorcinol, gallic acid and catechin respectively. Thus, it is indicative of the fact that catechin gallate available from the serum is further metabolized into catechin and gallic acid as end products in the mammary gland. IN-DEL-2004-01831A
