Determination of Amino Acids of Cultivated Species of the Genus Primula L.

Abstract

Throughout many years, plants using not only as a source of the meal but also in the fight against diseases. Among these plants are rock primrose (Primula saxatilis Коm.), Julia’s primrose (Primula juliae Kusn.), and drumstick primrose (Primula denticulatа Smith.). The aim of our research was to determine the content of amino acids in these plants with the future prospects of their application as officinal medicinal plant raw material. The amino acids of the leaves of cultivated species of the genus Primula L. determined by the HPLC method. 16 free and 16 bound amino acids were identified in the cultivated species of Primula L. High concentrations of the free amino acids that as L-glutamic acid, L-aspartic acid, and L-alanine predominate in all the plants analyzed. Among the bound amino acids in the leaves of cultivated Primula species prevail, L-glutamic acid, L-aspartic acid, L-lysine, and L-leucine. The results show that rock primrose, Julia’s primrose, and drumstick primrose are the rich source of amino acids. The specific metabolic processes in which these amino acids are involved may be related to the medicinal properties of plants according to their use in traditional medicine, and hence may contribute to the understanding of their healing properties.
