This study was conducted to compare the antioxidative effects of Dendranthema zawadskiivar. latilobum(Maxim.) Kitam and D. zawadskiivar. yezoense(Maek.) Y.M. Lee & H.J. Choi due to the harvest date. Harvestedsamples at May 9th (early), July 17th (middle) and September 3rd (late stage) were extracted with 80% ethanol, andbiological activities and antioxidant substance contents were detected. The earlier harvested samples showed the highermoisture contents and extraction yields. DPPH radical scavenging effect of early harvested D. zawadskiivar. latilobum(Maxim.) Kitam (RC50 = 0.128 mgmL-1) was similar to BHT (0.121 mgmL-1). ABTS radical scavenging effects ofboth species harvested at early stage were higher than that of ascorbic acid which was well-known natural antioxidant.However, both species harvested at late stage showed the highest Fe2+ chelating effect, but it was lower than that ofEDTA. Total polyphenol and flavonoid contents of both species were higher when samples were harvested earlier stage.However, both species harvested at early stage contained more total polyphenols (79.93 and 75.10 mgg-1) thanflavonoids (57.84 and 54.91 mgg-1).
