Method of increasing hydroxyproline and arginine content of Soybean leaves

摘要

The present invention relates to a method for increasing the content of hydroxyproline and arginine in soybean leaves. When soybean leaves 40 days after sowing are treated with ethylene at a concentration of 200 ppm, The content of free amino acids was significantly increased to about 3 ~ 7 days after treatment. And the content of essential amino acid was about 10 times higher than that of non-ethylene-treated canola In particular, gamma-aminobutylic acid, a typical functional material, was increased about 2-fold, hydroxyproline was increased about 10-fold, and arginine was increased about 30-fold or more. It was confirmed that the activity of the elastase related to the skin wrinkle formation was remarkably inhibited, The method of treating the leaves can be usefully used as a method for increasing the content of hydroxyproline and arginine in the bean leaves, and the composition containing the canola leaves, the extract of the bean leaves, or the fractions thereof can be used as a skin cosmetic material and a pharmaceutical material .;
