Studies on the Mucilage for the Manufacture of Korean Hand-Made Paper -Part II. Detection of Amino acids in the Mucilage of Ulmus coreana, Nakai Root-

느릅나무근(根) 점액(粘液)은 단백질(蛋白質)을 함유(含有)하며 그 함량(含量)은 황촉규근(黃蜀葵根) 점액(粘液)의 단백질(蛋白質) 함량(含量)보다 크다. 점액(粘液)에서 alanine, aspartic acid, glutamine, glutamic acid, hydroxyproline, isoleucine, leucine, proline, phenylalanine 및 tyrsine 등(等) 아미노산(酸_이 검출(檢出)되고 또 이 점액(粘液)에 무수(無水) ethanol을 가(加)하여 얻은 점질물(粘質物)의 가수분해(加水分解) 생성물(生成物)에서는 alanine, aspargine, aspartic acid, glutamine, glutamic acid, hydroxyproline, isoleucine, leucine, methionine, proline, phenylalanine, serine, tyrosine 그리고 valine등(等) 여러 종류(種類)의 아미노산(酸)이 검출(檢出)되었다.

The amino acids in the mucilage and its hydrolyzed products from Ulmus coreana, Nakai root were detected by thin layer chromatography. The mucilage contained 10 kinds of amino acids; alanine, aspartic acid, glutamine, glutamic acid, hydroxyproline, isoleucine, leucine, proline, phenylalanine and tyrosine. In the hydrolyzed mucilage 14 kinds of amino acids were detected; alanine, aspargine, arpartic acid, glutamine, glutamic acid, hydroxyproline, isoleucine, leucine, methionine, proline, phenylalanine, serine, tyrosine and valine.
