Data are expressed as mean ± SD (n = 3) (¹calculated by comparing to thiophene). Values in the same column followed by different letters indicate significant differences at p < 0.05 according to Duncan's multiple range test; ns: not significant, ^∗: significant at p < 0.05, and ^∗∗: significant at p < 0.01 level.
