The results of antioxidant activity analysis suggested that both live and heat-killed *L. plantarum* NA possessed capacity for scavenging free radicals, including 2,2-diphenyl-1-picryl-hydrazyl (DPPH), 2,2'-azino-bis-(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), hydroxyl radicals and superoxide radicals. The ABTS scavenging activity of heat-killed cells (38%) was significantly higher than that of viable (19%) *L. plantarum* NA.
