The present study was conducted to evaluate the antioxidant and anti-inflammatory effects of
the ethanol extracts (PBE) and the non-alkaloid fractions, the crude saponin extract (CSE) and the crude
flavonoids extract (CFE), of Fritillaria ussuriensis Maxim (PB). The antioxidant activity of PB extracts decreased in the order: CFE >CSE > PBE. All the administered groups produced significant anti-inflammatory effects on the three animal models. The results demonstrated that the different fractions of PB have
different responses with different antioxidant methods and anti-inflammation animal models. CSE showed
the best antioxidant and anti-inflammatory activities and CFE and PBE followed.
