Amino acid composition of Veronica teucrium L. herb

Abstract

By HPLC method amino acid composition of V. teucrium L. herb had been studied, 23 amino acids have been identified and quantified, of which 21 are free and 19 are bound, 10 essential amino acids have been found – threonine, valine, methionine, isoleucine, leucine, phenylalanine, lysine, histidine, tyrosine and arginine. The content of free amino acids is 0.48%, the total content of amino acids after hydrolysis – 2.37%, the content of bound amino acids – 2.03%. In V. teucrium L. herb quantitatively dominated (mg/100g) arginine, serine, glycine, proline, phenylalanine, leucine, threonine and histidine. Among free amino acids asparagine and aspartic acid, alanine, glutamic acid and γ-aminobutyric acid dominated. Among bound amino acids the dominant were serine, arginine, glycine, threonine, proline, leucine, phenylalanine, histidine.
