Table 1 shows the DPPH and ABTS radical-scavenging capacities of the fractions from D.
cambodiana. The results illustrated that the DPPH and ABTS radical-scavenging capacities of various
solvent fractions increased with increasing concentration, and all the regression equations were
significant at p < 0.05, so all the fractions had some DPPH and ABTS free radical-scavenging
