Data expressed as mean ± standard deviation of triplicate determination. Data followed by different superscript alphabet along the same column are significantly different (p < 0.05). The high significant levels of the parameters were in the order of a < b < c. Data with superscript alphabet “a” are significantly lower than data with superscript alphabet “b” while data with superscript “b” are lower than data with superscript alphabet “c” at p < 0.05.
