To develop a natural antioxidant from three Chrysanthemum species, flower and shoot extracts of Chrysanthemum frutescens, Chrysanthemum morifolium and Chrysanthemum zawadskii ssp. naktongense were obtained and their phenolic compound contents, scavenging effects on DPPH and ABTS radicals, ferrous ion chelating effects and inhibition activity on lipid peroxidation of linoleic acid were studied. Shoots of C. morifolium showed the highest levels in all above mentioned analyses. Especially, shoot extract of C. morifolium had high scavenging activities on ABTS radicals, similar to ascorbic acid or BHT. Ferrous ion chelating effect was the lowest in a C. morifolium shoot extract, but the highest in a C. morifolium flower extract. Inhibition activity on lipid peroxidation of linoleic acid was the highest with C. frutescens and C. morifolium shoots, but activity was lower than BHT. From present study, a shoot extract of C. morifolium is demonstrated as a valuable source for the development of a natural antioxidant. However, due to its low levels of ferrous ion chelating effects and inhibition activity on lipid peroxidation, a combination of other antioxidants with C. morifolium extract is recommended for the development of a new antioxidant.
