Samples are crude ethanol extract (Md EtOH), n-hexane fraction (MdH), chloroform fraction (MdC), ethyl acetate fraction (MdEA), n-butanol fraction (MdB) and water fraction (MdW). Data are expressed as means ± standard deviation from three experiments. Different superscripts in the same row (a, b, c, d, e) indicate significant difference (p < 0.05); nc = not calculable.
