Abstract

Soluble extract of Macrosiphum euphorbiae (Thomas) was separated electrophoretically into fast moving and slow moving protein bands These bands were fractionated and studied for their amino acid content. Glycine was the most prominent amino acid in both bands. Aspartic acid, serine, glutamic acid, alanine, and leucine were present in high concentrations in the fast moving protein band. Lysine, alanine, valine, tyrosine, and phenylalanine were present in traces in the slow moving protein band.
