- Abstract
- In order to obtain basic data necessary for the utilisation of aerial parts from Plarycodon grandiflorum as a functional substance in Korea, the antioxidant activities of solvent fractions from the ethanol extract of P. grandiflorum aerial parts were examined. The butanol fraction from P. grandiflorum showed the most potent antioxidant activities in each assay, showing 91.31% in the DPPH radical scavenging method, 99.62% in the ABTS radical scavenging method, 7.84% in the reducing power method, and 1.29% in the FRAP method at a concentration of 10 mg/ml. The DPPH, ABTS, reducing power, and FRAP assay indicated that the butanol fraction of aerial parts of P. grandiflorum was the most potent radical-scavengers and reducing agents compared to the other two extracts. Therefore, our study verified that the butanol fraction has strong antioxidant activities which are correlated with its high level of phenolics, particularly luteolin-7-O-glucoside and apigenin-7-O-glucoside. This extract of A grandiflorum aerial parts can be utilised as an effective and safe source of functional food materials such as natural antioxidants. (C) 2009 Elsevier Ltd. All rights reserved.
