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-

한지(韓紙) 초조용(抄造用) 점액(粘液)에 관한 연구(硏究) -제2보(第二報). 느릅나무근(根) 점액(粘液)의 아미노산류(酸類)의 검색(檢索)-

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.

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.
