This study was conducted to compare flavonoids and anti-inflammatory effects in Korean Chrysanthemum species. Leaf samples were identified using HPLC/MS with five flavonoids: luteolin-7-O-rutinoside, luteolin-7-O glucoside, apigenin-7-O-glucoside, apigenin, and acacetin-7-O-rutinoside. Leaf extracts from four taxa dose-dependently suppressed LPS-stimulated NO production significantly (p<0.05) inhibited production of LPS-induced PGE2 compared with controls. The extracts reduced the LPS-induced expressions of inducible NO synthase and cyclooxygenase-2 and inhibited LPS-induced tumor necrosis factor-α and interleukin-6 production for anti-inflammatory effects.
