Abstract:		"Coreopsis is a flowering plant belonging to the Asteraceae family. It is an ornamental plant native to the Americas, Asia and Oceania and its flower is used as a raw material for tea and food manufacture in China. In this study, new cultivars of C. rosea ('golden ring') were developed via radiation-induced mutation of the original cultivar, 'pumpkin pie'. The chemical composition and antioxidant activities of flowers belonging to three different Coreopsis cultivars were evaluated: 'golden ring', 'pumpkin pie' and 'snow chrysanthemum' (coreopsis tea; C. tinctoria). The volatile compounds were characterized via gas chromatography-mass spectrometry (GC-MS) and 50-59 oils representing 95.3-96.8% of the total volatile compounds in these flower materials were identified. 'Golden ring' contained a high amount of fatty acids (38.13%), while 'pumpkin pie' and 'snow chrysanthemum' teas were rich in aliphatic amides (43.01%) and esters (67.22%), respectively. The antioxidant activities of the volatile oils of these cultivars were evaluated using 1,1-diphenyl-2-picrylhydraxyl (DPPH) and 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging assays. The volatile extract of 'golden ring' showed higher antioxidant activities compared with the extracts of the other cultivars. Therefore, 'golden ring' can be used for further development as a raw material for tea manufacture or as a dietary supplement"
