Introduction. Garden asparagus (Asparagus officinalis L.) is anedible, ornamental and medicinal plant with antioxidant, diuretic and hypotensive activity. The Aim of the Study. Determination of morphological features and analyze the qualitative composition and quantitative content of amino acids in the young shoots of Asparagus officinalis, gathered in Ternopil region. Research Methods. The object of the research was the young shoots of Asparagus, which were collected at the beginning vegetation period and dried at a temperature of 25–35 °C. The composition of amino acids was analyzed using gas chromatographic-mass spectrometric method. Results and Discussion. We analyzed the morphologikal features of young shoots of Asparagus. In the studied raw material, 11 free and 13 bound amino acids were identified. The absence of L-glycine and L-tyrosine in the free state was noted. The total content of free amino acids was 1,22 mg/g, while the bound ones were 78,85 mg/g (of the total content of these compounds identified in the plant). Conclusions. The qualitative composition and quantitative content of amino acids in young shoots of Asparagus officinalis have been established. Among the detected amino acids the largest amound share is L-leucine (12,45 mg/g), L-proline (11,36 mg/g) and L-phenylalanine (9,7 mg/g). In the free state, L-valine, L-lysine, L-proline and L-aspartic acid predominated.
