The antioxidant activity, total phenol content, and inhibitory effect of xanthine oxidase (XOase) for six different medicinal plant complexes such as Achyranthes japonica, Acanthopanax sessiliflorus, Carthamus tinctorius, Eucommia ulmides, Viscum album, and Caragana koreana were investigated in this study. The free radical scavenging activity values using DPPH(2,2'-diphenyl-1-picrylhydrazyl) and ABTS[2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt radical cation] analyses were found to be 532.03±86.60 μg/mL and 1376.50±35.01 μg/mL, respectively, in 95% of ethanol extracts among six medicinal plant mixed compositions (6MPMC). The total phenolic content in 70% ethanol extract of 6MPMC was 125.19±1.34 mg GAE/g. The inhibitory activity against XOase was highest at 33.20±0.17% in the 70% ethanol extract of 6MPMC. In the antimicrobial activity test of 6MPMC, the minimum inhibitory concentration (MIC) value showed activities against V. litoralis and E. coli in 70% and 95% ethanol extracts, and these two microorganisms were created in clear zones by method of paper disc diffusion. These results suggest that the 6MPMC, composed of Achyranthes japonica, Acanthopanax sessiliflorus, Carthamus tinctorius, Eucommia ulmides, Viscum album, and Caragana koreana, have both antioxidant and antimicrobial activities and, therefore, may serve as a functional health food product.
