Antioxidant, anti-inflammatory and anti-nociceptive activities of the flavonoids from Trollius chinensis Bunge
摘要
The antioxidant, anti-inflammatory and anti-nociceptive mechanisms of action of flavonoids in Trollius chinensis Bunge (TCB) were systematically analyzed. By this means, the TCB extracts, prepared by ethanol/water (8:2, v/v, 24 h) at room temperature, displayed significant antioxidant activity by capturing superoxide anion (O2·), hydroxyl radical (·OH), DPPH and ABTS free radicals, reducing ferricyanide power and chelating ferrous irons. The anti-inflammatory activity of the TCB extracts was evaluated by carrageenan-induced paw edema, xylene-induced ear edema and acetic acid-induced vascular permeability. The anti-nociceptive activity of the TCB extracts was evaluated by the acetic acid-induced writhing, the formalin-induced paw licking, the hot plate test and the tail immersion test. All results revealed that TCB is a good source of functional food materials which concurrently had the antioxidant, anti-inflammatory and anti-nociceptive effects. This study will provide valuable information for the further development of TCB as functional foods or in pharmaceutical industries in the near future.
