|
In this study, we investigated the antimicrobial and antifungal activity from the wild seaweeds of Jeju island. The active ingredients of the seaweeds were prepared by 80% methanol extraction. Antimicrobial and antifungal activity of seaweed extracts was examined. We found that 6 plant extracts among 45 plants, namely, Codium contractum, Undaria pinnatifida, Ishige sinicola, Ishige okamurai, Ishige okamuriai, Ecklonia cava, Hizikia fusiformis, Ulva fasciata, Ulva pertusa, Sargassum siliquastrum, Ecklonia kurome, Gracilaria textorii, significantly inhibited growth of harmful microorganisms. Additionally, according to DPPH assay. 2 plant extracts were found to have antioxidant activities. Taken together, these results suggest the possibility that 11 plant extracts can be utilized as an antimicrobial agent.
