Abstract
Objective: The antioxidative properties of Chinese medicine Tussilago farfara were determined by spectrophotometry. Methods: The anti-oxidation activity of petroleum ether, ethyl acetate and n-butanol extracts from ethanol extract of Tussilago farfar were studied, using DPPH free radical scavenging, hydroxyl radical scavenging, and total reducing power determination. Results: Compared with the Vc activity of the positive control, the extracts of ethyl acetate part and the n-butanol part showed significant antioxidant activity, and the antioxidant activity in the ethyl acetate part was higher than Vc. Conclusion: Antioxidant activity of ethyl acetate extract is better than vitamin C, N-butanol extract also has obvious antioxidant activities.
