the linear coefficient for chloroform is much larger than the
other pure solvents producing much smaller antioxidant activities.
On the other hand the ethanol coefficient is smallest but significant
at the 95% confidence level, indicating the highest antioxidant
activities. As can be seen from the model coefficient values in the
equation synergic and antagonistic binary and ternary effects are
significant. The (1:1:1 v/v/v) ethanol:dichloromethane:chloroform
interaction is the most important antagonistic effect having the
largest ternary values, following by the (1:1:1 v/v/v) ethanol:ethyl
acetate:dichloromethane and the (1:1:1 v/v/v) ethyl acetate:
dichloromethane:chloroform ternary mixtures.
