영문 초록

Throughout the formation of ginseng seeds, the changes of free amino acids were inspected by thin-layer chromatography applying the mixed layer of silicagel and micro-crystalline cellulose. 15 amino acids, alanine, valine, leucine, phenylalanine, hydroxyproline, proline, serine, threonine, aspartic acid, tyrosine, glutamic acid, lysine, arginine, β-alanine, cysteic acid, and two amides, asparagine and glutamine, were detected throughout the all period of ginseng seed formation. Two amides, aspsragine, and glutamine, were found in large quantity at the early stage of ovule formation but their concentrations decreased at the flowering time. Proline was detected from the early stage of flower organ formation and was detected in the largest spot at the microspore stage. At the pollen mature stage and the flowering stage the amount of proline decreased and after the falling of blossoms it was rarely found. Generally speaking, from the flowering time the proportion of free amino acids in the equivalent wet weights of endosperm declined with advancing endosperm maturity. It was noticeable in relation to the metabolism of ginseng that greater amount of cysteic acid, a sulfur containing amino acid is found in ginseng seeds than in the other plants.
