Abstract
|
|
|
|
The aim of this study was to measure and compare polyphenol content, antioxidant, and antiinflammatory activity of six halophytes (Limonium tetragonum, Suaeda glauca, Suaeda japonica, Salicornia europaea, Triglochin maritimum, and Sonchus brachyotus). Depending on the total polyphenol content, the plants were categorized into two groups: (1) a high total polyphenol content group that included L. tetragonum, S. brachyotus, and S. europaea, and, (2) a low total polyphenol content group consisting of S. glauca, T. maritima, and S. japonica. Antioxidant activity was evaluated using DPPH and hydroxyl radical scavenging assays, and by measuring ROS. Anti-inflammatory activity was evaluated by measuring NO and PGE2. L. tetragonum and S. brachyotus, that have high polyphenol content, also showed strong antioxidant activity. In addition, L. tetragonum, S. brachyotus, and S. europaea showed good anti-inflammatory activity. Consequently, the total polyphenol content was thought to be related to antioxidant and anti-inflammatory activity. Therefore, S. brachyotus and L. tetragonum are good candidates for use in pharmaceuticals and functional foods.
