The Antioxidant and Anticancer Effects of Butterbur (Petasites japonicus) Extracts

  • 5

The antioxidant activities of the extracts of butterbur (Petasites japonicus) derived from different extraction methods were investigated. SOD (superoxide dismutase)-like activity differed according to the extraction solvents, showing a greater antioxidant effect with ethanol solvent than that of water. Ethanol extracts of butterbur leaves showed higher SOD-like activity of 96.7% than those of water extracts. The contents of polyphenolic compounds were higher in water extracts than those in ethanol extracts. The highest content of polyphenolic compounds was 223mg/g dry weight for butterbur leaves. EDA of butterbur roots was 61.5% in the water extract and EDA in butterbur leaves was 34.9% in the ethanol extract. The anticancer effects with the extracts of butterbur were experimented by fractionations with different solvents. 41.9% of the growth of stomach cancer cells, SNU-719, were inhibited and also 72.7% of the growth of liver cancer cells, Hep3B, were inhibited by the butanol fractions of butterbur, while not affecting the growth of normal cell, DC 2.4.
