- l-Valine solutions in water and phosphate buffer were treated with nonthermal plasma generated by using a dielectric barrier discharge (DBD) device and the products generated after plasma treatments were characterized by 1H NMR and GC-MS. Our results demonstrate that l-valine is decomposed to acetone, formic acid, acetic acid, threo-methylaspartic acid, erythro-methlyaspartic acid, and pyruvic acid after direct exposure to DBD plasma. The concentrations of these compounds are time-dependent with plasma treatment. The mechanisms of l-valine under the DBD plasma are also proposed in this study. Acetone, pyruvic acid, and organic radicals •CHO, CH3COCH2OO• (acetonylperoxy), and CH3COC(OH)2OO• (1,1-dihydroxypropan-2-one peroxy) may be the determining chemicals in DNA damage.
