Lithospermum erythrorhizon, medicinal herb has been used as foods and cosmetics colourings for many years. In this studies, L. erythrorhizon was extracted by microwave extraction processes at 1300 W and 120 ℃ for 5 minutes. Its antioxidant activities were compare to three extracts from other processes : water extraction for 24 hours at 100 ℃ and 60 ℃, and 70% ethyl alcohol extraction for 24 hours at 60 ℃. The total phenol content of the extract from microwave extraction was measured as 10.12 μg/㎖ヲ, compared to 8.21, 8.17, 7.74 μg/㎖from water extraction at 100 ℃ and 60 ℃, and 70% ethyl alcohol extraction at 60 ℃, respectively. The extract from microwave extraction effectively inhibited SOD-like activity to 16.56%, which was higher than 11.41%, 10.28% and 8.25% from water extraction at 100 ℃ and 60 ℃, and 70% ethyl alcohol extraction at 60 ℃, respectively. The extract from microwave process also showed the strong reducing power as 3.09% optical density, compared to 2.7% from 70% ethyl alcohol extraction at 60 ℃. From the results, microwave extraction processes could enhance antioxidant activities of L. erythrorhizon by increasing the extraction yields of total phenol contents by intensifying input power at short periods of time.
