Investigation of amino acids content in the herb and tubers of Stachys sieboldii

The aim of this research was the comparative study content amino acids in herb and tubers Stachys sieboldii. acid composition raw materials carried out using high-performance liquid chromatography (HPLC). results obtained have shown that aerial parts plants investigated higher than underground organs. Free bound L-aspartic acid, L-proline, L-phenylalanine were present analyzed samples greatest amount. Moreover, L-cysteine found only sieboldii amounts (8.11 mg/g). This established most suitable are prospective for further pharmacological studies.
