¹⁾ ABTS radical scavenging activities are expressed as mg vitamin C equivalents (VCE)/100 g sample.
²⁾ Data are expressed as a mean±SD (n=3).
^a-dMean in a column by different superscripts are significant different at p<0.05 by Tukey’s multiple range test.
^A-DMean in a row by different superscripts are significant different at p<0.05 by Tukey’s multiple range test.
