The comparative activities of aqueous, ethanol, and methanol extracts from Thuja orientalis leaf(TOL) and fruit(TOF) were tested by in vitro experimental models of linoleic acid peroxidation by α,α‘diphenyl-β-picrylhydrazyl (DPPH) radical scavenging activity and ferric thiocyanate and thiobarbituric acid (TBA) methods. In addition, the bio-active materials (phenolic compounds, flavonoeds, fatty acid and minerals) were measured. Total polyphenolics displayed the highest content in TOL methanol extracts (16.02%) and the lowest content was TOF water extract (6.11%). The highest flavonoid content in methanol extracts was produced by TOL (0.25%) and the lowest was water extract of TOF (0.03%). Major mineral contents (mg%) of TOL and TOF were Ca by 986.67 and 1011.67, K by 68.83 and 120.23, Mg by 15.97 and 11.83, respectively. The highest free radical scavenging activity showed in methanol extract by 92.84% at 0.1% additional level from TOF and in ethanol extract by 73.37% at 0.1% additional level from TOF. Free radical scavenging activity was stronger in TOL than that TOF. In antioxidative activities determined by thiocyanate and TBA methods against lipid peroxidation using linoleic acid, methanol extracts from TOL 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 TOL and TOF.
