| Abstract: | A new record species of Tussilagofarfara L. was reported to Changbai Mountain, and the antioxidant activity was also evaluated in the present study. Results suggested that the ethyl acetate （EA） and n-butanol fractions of the T. farfara extract showed strong free radical scavenging activity and inhibitory activity on pyrogallol autoxidation. HPLC assay suggested that the phenolic compounds 3-O-caffeoylquinic acid and 3, 5-O-dicaffeoylquinic acid play an important role in the potent antioxidant activity of the EA fraction. The content of 3, 5-O-dicaffeoylquinic acid 8.55% in T. farfara collected from Changbai （CB） is much higher than that in T. farfara collected from other provinces （0.51%）, suggesting that CB T. farfara, a good resource of natural antioxidant, has the potential to be used in the manufacturing of foods and medicines. |
