  • Method for preparing ramalin
    Patent number: 8865934
    Abstract: The present invention relates to a method for synthesizing ramalin, and more particularly to a method for synthesizing ramalin, which comprises allowing 2-hydrazinylphenol to react with L-glutamic acid having a protected carboxyl group at C-1 and a protected amino group at C-2, and a method for preventing decomposition of the ramalin. According to the present invention, ramalin having excellent antioxidant and anti-inflammatory activities can be synthesized in high yield, and thus can be produced in large amounts. In addition, ramalin can be stably maintained for a long period of time, and thus can be easily used for industrial purposes.
