概要	In this research, production of protein-like substance by pulse electric discharge plasma was carried out using amino acid in supercritical carbon dioxide. Moreover, nano pulse electric discharge plasma was also formed in supercritical fluids; reaction of amino acid was also observed. Aiming at establishment of a new reaction field, we did fusion research of supercritical fluids and electric discharge plasma. In this experiment, argon at the pressurized state was used as a reaction medium. Initially, alanine aqueous solution of 0.1 mol/L was loaded to a plasma reactor (inner volume: 600 mL) and reached under the desired conditions (290-308 K and 1-10.8 MPa). They were then analyzed by high-performance liquid chromatography (HPLC) and matrix-assisted laser desorption time of flight mass spectroscopy (MALDI TOF-MS). The possibility of polymerization of alanine was realized from the compound after electric pulsed discharge plasma processing.
