Abstract
|
|
|
|
The total phenolic contents and antioxidative activities of the ethanol and methanol extracts from 9 Korean medicinal herbs were tested for the application of skin care products such as soaf and lotion. For the evaluation of antioxidative activity of the extract the method of electron donating ability with resolution reagent DPPH(1 ,1-diphenyl-2-picryl hydrazyl) and TBARS (Thiobarbituric acid reactive substances) value were used in comparison with α-tocopherol and BHA. As the results, the total phenolic contents of the extracts calculated as chlorogenic acid were ranged from 0.063-0.124 mg/ml. All the medicinal plant extracts showed some appreciable antioxidative effects. Among them, Zanthoxylum piperitum, Cinnamomum cassia and Caesalpinia sappan were shown to have relatively high antioxidative effects comparable with BHA and α-tocopherol..
