The comparative activities of aqueous, ethanol, and methanol extracts from Akebia quinata were tested by in vitro experimental models of linoleic acid peroxidation by thiocyanate and thiobarbituric acid(TBA) methods and scavenging activities of free radicals by DPPH (α,α'- diphenyl-β-picrylhydrazyl). In addition, bio-active materials were also measured. The extract yield of each solvent extracted from Akebia quinata was 12.49% in aqueous, 7.38% in ethanol, and 8.47% in m ethanol, respectively. The highest concentration of phenolic compounds and flavonoids in the methanol extracts of Akebia quinata were 16.58% and 11.22%. Major mineral contents of Ca, K, Mg and Zn. Major fatty acids were palmitic acid, linolenic and Cis-9-Oleic acid. The highest free radical scavenging activity was found in the methanol extracts by 80.86% at 0.5% additional level. In antioxidative activities determined by thiocyanate and TBA methods against lipid peroxidation using linoleic acid, ethanol extracts showed the highest antioxidative activity at all treatment concentrations. These results may provide the basic data to understand the biological activities of bio-active materials derived from Akebia quinata.
