The major objective of this study was to investigate the antioxidant activities of methanolic extracts from different parts (flower, leaf stem, and root) of Chrysanthemum zawadskii by employing various in-vitro assay systems. The extraction yields from the flower, leaf stem, and root were 18.347, 12.93, and 11.33, respectively. The total polyphenol content was highest in the flower (17.16 mg/100 g) and lowest in the root (11.33 mg/100 g). The antioxidant activities were raised within creasing amounts of extracts, and the extracts from the flower showed the highest effect on the superoxide anion radical scavenging, metal chelating on ferrous ions and reducing power. In addition, the leaf stem also showed good antioxidant activity in various systems. These results suggest that the methanolic extracts from the flower and leaf stem possess excellent antioxidant activities and may thus serve as potential sources of natural antioxidants.
