Abstract
|
|
|
|
The objective of this study was to investigate the antioxidant activities and anthocyanin profiles in the anthocyanin rich fraction (ARFAM) of Aronia melanocarpa, which are considered functional substances and are available as food coloring agents in Korea. Anthocyanins were identified by reversed-phase C18 column chromatography and HPLC-DAD-ESI/MS analysis. The antioxidative activity of the acidic ethanol extract (AME) and the anthocyanin-rich fraction (ARFAM) was determined by scavenging of the diphenylpicrylhydrazyl (DPPH) radical, the hydroxy radical, and the superoxide anion in addition to reducing power using a commercial antioxidant as a reference.
