RESUMEN

Little is known of plasma-mediated relations between major food components and their biological capacities. In the present work, the effects of dielectric barrier discharge (DBD) plasma irradiation on pure sesamol and sesame oil were investigated using spectroscopic (LC-MS, NMR) and bioassay methods. Sesamol was degraded when subjected to plasma irradiation for 40 min, and the exposed products exhibited improved anti-glycation capacities against advanced glycation end products (AGEs) formation and better ONOO- scavenging ability. Structures of newly formed compounds were determined spectroscopically. Quantitative LC-MS analysis of the major products generated in sesamol and sesame oil was achieved using isolates 1-4 of purified sesamol plasma treated for 40 min. These results indicate that the predominant chemical changes induced in sesamol and sesame oil by DBD plasma treatment might enhance biological properties.
