Abstract

Fine rice bran, fish meal, ipil-ipil leaf meal, copra meal, soy-bean oil meal, ground yellow corn, corn gluten feed, and mongo seed meal were analyzed for glycine. Fish meal and soybean oil meal were found most promising. Fish meal contained the highest amount of glycine (69.00 mg m. per 100-gram sample), as well as a high percentage of crude protein (65.10. Soybean oil meal had the second highest amount of glycine (40.70 sgm. per 100-gram sample) and a recommend-able amount of crude protein (44.81%). Two-dimensional paper chromatographic analyses revealed the presence of glycine, glutamic acid, arginine, aspartic acid, serine, proline, tryptophan, pherylalanine, lysine and other amino acids. Ulycine was well separated in some chromatograms, but often occurred in mixtures with other amino acids, like glutanic acid, serine, and arginine.
