Abstract
|
|
|
|
82 species of Korean medicinal plants were measured to their SOD (superoxide dismutase) activity, total phenol and individual phenol compounds. The SOD activity of medicinal plants was varied from 3.67% to 48.3%, and especially, 4 species including Polygala tenuifolia Willd. showed activity over 40% higher than other species. The 16 individual phenol compounds concentrations have a severe variation in medicinal plants. Codonopsis lanceolata is the highest concentration (12,176;{mu}g/g), and 10 species including Glycyrrhiza uralensis Fisch were showed to concentrations more than 1,000;{mu}g/g. And also, salicylic acid was generally found in many plants, but trans-cinnamic acid, naringenin and kampferol was little found in plants. The total phenol by Folin-Dennis methods showed a respectively variation (3{sim}249.731;{mu}g/g) in 82 medicinal plants, and 7 species including Astragalus membranaceus showed low total phenol concentrations less than 10;{mu}g/g. In conclusion, we expect that selecting medicinal plants with high biological activity might develop to chemicals related to antioxidants, as well as these become most popular substance at many industrial materials, and suggest to more researchs in future.
