This study was designed to assess the anti춐xidative and biological activities of extracts from Saururus chinensis. It is more effective to use elicitor than non-treated elicitor when extracting phenolic compounds. Elicitor춗reated S. chinensis showed higher total phenolic content than the control group. Anti춐xidative activity of elicitor춗reated S. chinensis extract increased in a concentration춄ependent manner as concentration increased from 1.5 mg elicitor/leaf 1 g (elicitor 1.5) to 3.0 mg elicitor/leaf 1 g (elicitor 3.0). Moreover, 70% ethanol extract showed higher anti춐xidative activity than water extract. Hypertension inhibitory activity of the elicitor춗reated group was much higher than that of the non-treated group. Elicitor 3.0 showed a 2춆old higher inhibitory effect and higher than captopril, which was the positive control. Elicitor춗reated S. chinensis extract showed high gout preventative activity compared to the non-treated group. It also showed higher xanthine oxidase inhibitory activity than the positive control allopurinol. Thus, it can be expected to be used as a source in the medical industry for hypertension inhibition and gout prevention. Elicitor춗reated S. chinensis extract showed partial anti춎icrobial activity. Elicitor 1.5 showed Streptococcus mutans inhibitory activity against cavities, which was not observed in the control group. Elicitor 3.0 not only showed cavity preventive activity but also a Helicobacter pylori inhibitory effect, which is directly related to stomach ulcer and gastritis. Therefore, elicitor treatment during S. chinensis cultivation will increase total phenolic compound content in the plant source and increase bioactivity, which will yield high quality for industrialization.
