Anti-oxidative Activity and Chemical Composition of Various Heracleum moellendorffii Hance Extracts

Anti-oxidative activities of Heracleum moellendorffii Hance extracts were measured after extraction with 50% (v/v) ethanol or water (at or ). The total polyphenol content was highest (64.73 mg GAE/g) in extract from 50% ethanol extraction at . In extracts obtained by water extraction at and , the total polyphenol contents were 39.78 mg GAE/g and 23.17 mg GAE/g, respectively. The antioxidant activities of the ethanol extract at were highest, as assessed by DPPH radical scavenging activity (69.14% at 50 ppm), reducing power (OD 0.93), and radical-scavenging activity (85.62% at 1,000 ppm). At , the antioxidant activity of the 50% (v/v) ethanol extract was 8-20% higher than that of the water extract. Also, the chemical composition of extract from ethanol extraction at was analyzed. The levels of moisture, crude protein, crude fat, and crude ash were 6.38%, 4.35%, 0.67%, and 1.96%, (all w/w), respectively. The Na, K, Mg, Zn, Fe, Ca, and P contents of the extract were 53.41, 398.26, 5.80, 0.40, 5.27, 3.56, and 47.17 mg/100 g, respectively. The total levels of polyphenolic compounds and flavonoids in the ethanol extract were 64.73 mg GAE/g and 49.54 mg RE/g.
