A recent study indicated that Hime Ukogi (Eleutherococcus sieboldianus) used for a fence and food in Yonezawa City had antioxidant with electron spin resonance. Biological antioxidant potential (BAP) tests, namely, a ferric reducing antioxidant power reducing assay and a free-radical scavenging activity test, were developed by Napoli University. In this study, BAP levels of some vegetables, including Hime Ukogi, were measured. According to the severity of antioxidant status impairment based on the results of the BAP tests, the Ukogi's BAP of 13,440 μmo/L might have a strong potential of antioxidant activity. Therefore, this finding suggests that Hime Ukogi may have the potential of being a strong antioxidant food.
