Ferric-reducing activities of different solvent extracts from Ribes diacanthum Pall

Sample extract1)	mmol Fe(II)/mg/extract2)

¹⁾Same extracts as created in Table 1.

²⁾Concentration of substance having ferric-TPTZ reducing ability expressed as μmol Fe(II) equivalents

³⁾Measurements were done in triplicate and values represent mean±SD.

^a-dMean values followed by different superscripts in a column are significantly different by Duncan’s multiple range test at p<0.05.
