느릅나무근根 粘液에 관한 硏究(3) : 粘質物의 Amino Acid 分析 Part 3. Detection of amino acids in the mucilage = Studies on the Mucilage of Ulmus Coreana , Nakai Root

다국어 초록 (Multilingual Abstract)

Ulmus Coreana Nakai root and Abelmoschus Manihot Medic root extract plenty of mucilage in water. The viscosity of the mucilage of Abelmoschus Manihot medic root decreases fast and that of Ulmus coreana Nakai root decreases slowly
Under the hypothesis that the chemical components in the two kinds of the mucilage, are similar. The amino acids in the mucilage are hydrolyzed mucilage, that were extracted from Ulmus coreana Nakai root, were detected by the same method for Abelmoschus Manihot Medic root, using thin layer chromatography.
The results were as follows :
(1) The mucilage of Ulmus Coreana Nakai root contained ten kinds of amino acids : aspartic acid, glutamic acid, alanine, glutamine, hydroxyproline, tyrosine, proline, phenylalanine, isole-ucine and leucine.
(2) In the hydrolyzed mucilage of that root, 14kinds of amino acid were detected : aspartic acid, glutamic acid, serine, asparagine, alanine, glutamine, hydroxyproline. tyrosine valine, methionine, phenylalanine, proline, isoleucine and leucine. Especially, proline was detected as a large yellow spot.
(3) The optical density to the mucilage of Abelmoschus Manihot medic root leaving in nature, 19℃, decreased notably but decreased slowly in the mucilage of Ulmus Coreana Nakai root
