Experimental results recorded were means ± standard deviation
(SD) of triplicate determinations. Statistical significance
of the obtained results was analyzed by one-way analysis of
variance (ANOVA) and independent sample T-test using the
SPSS version 17.0 software (SPSS Inc., Chicago, IL, USA). The
EC50 values were obtained by interpolation or extrapolation from
linear regression analysis according to the references (Juan &
Chou, 2010; Lee et al., 2008; Xiao et al., 2014).Values were considered
to be significantly different from each other at a
significance level of p < 0.05
