ABSTRACT
Seventeen commercial chrysanthemum teas (Chrysanthemum morifolium and Coreopsis tinctoria) were extracted with hot-H2O, and examined and compared to the 75% methanol extracts for their chemical compositions using UPLC/Q-TOF-MS analysis. For the first time, 6, 8-C,C-diglucosylapigenin and eriodicyol-7-O-glucoside were detected in the Snow chrysanthemum, and acetylmarein was detected in HangJu, GongJu and HuaiJu. The extracts were also examined for their radical scavenging and anti-inflammatory activities in vitro. The hot-H2O extract of Kunlunmiju 1 had the greatest total phenolic content, and relative DPPH and oxygen radical absorbance capacity values of 12.72â¯mg gallic acid equivalents/g, 105.48 and 1222.50⯵mol Trolox equivalents/g, respectively. In addition, all the hot-H2O extracts suppressed the lipopolysaccharide-induced interleukin-6, IL-1ß and cyclooxygenase-2 mRNA expressions, and H2O2-induced intracellular reactive oxygen species production in cultured cells. The results from this research may be used to promote the consumption of chrysanthemum as a functional tea.
