Widely Targeted Metabolomic Analysis of Two Chinese Traditional Herbal Imperial Chrysanthemum Teas and In Vitro Evaluation of Their Hyperglycemia and Inflammation Enzyme Inhibitory Activities

Imperial chrysanthemum teas ‘Wuyuan Huangju’ (WYHJ) and ‘Jinsi Huangju’ (JSHJ), dried from the flowers of Chrysanthemum morifolium cv. Huangju, are traditional and popular herbal teas in China. However, their metabolite profiles and bioactivities remain unclear. In this study, we aimed to comprehensively elucidate the non-volatile and volatile metabo- lites of these two imperial chrysanthemum teas and assess their antioxidant activities and inhibitory effects on hyperglycemia and inflammation...
