There was an increasing interest that herbal medicine and natural material extracts were proved processes of antioxidant, cosmeceutical activity and the other effects. The aim of this study was to assess the antioxidant of extraction of four kinds from Prunus armeniaca L., Reynoutria elliptica, Curcuma aromatica, Lithospermum erythrorhizon. RE (Reynoutria elliptica) and CA (Curcuma aromatica) have good electron donating ability. The water and ethanol extract of RE at a 100 ppm concentration showed over 70%, the water extract at 500 ppm concentration showed 83% and the ethanol extract at 100 ppm concentration showed 86% of CA. Xanthine oxidase inhibition activity of the water extract of LE (Lithospermum erythrorhizon) at a 1,000 ppm concentration showed over 44%, on the other hand, RE showed in all lowest effect and there was no inhibition activity of a couple more extracts. In the measurement of nitrite scavenging activity, all extracts showed highly scavenging activity. Especially the water and ethanol extract of RE showed over 99% at 500 ppm, also LE showed over 40% at 10 ppm concentration.
