In the ethanolic extract of the Lesser centaury - Centaurii herba (Centaurium
erythraea Rafn., Gentianaceae) following amino acids were identified: Lysine
(Lys), Glutamine (Gln), Serine (Ser), Threonine (Tlu-), Valine (Val) and Leucine (Leu).
In the ethanolic extract of the Yarrow-Millefolii herba (Achillea millefolium L., Asteraceae)
following amino acids were identified: Glutamine (Gln), Glutamic acid (Glu),
Serine (Ser), Threonine (Th1-), Proline (Pro), Tyrozine (Tyr), Valine (Val), Phenylalanine
(Phe) and Leucine (Leu).
Investigation of the composition amino acids was carried with thin layer chromatography
method (TLC). Rf values of the identified amino acid were compared with the Rf
values of amino acids in the standard solutions
