F_PE (Petroleum ether fraction), F_DE (diethyl ether fraction), F_EtOAC (ethyl acetate fraction), F_R (residue fraction), F₂ (fraction (2), Gtn (gentamicin). Values of the mean in the same column referred by alike alphabetic characters are not significantly different when . Tukey’s HSD is used to separate the mean. Note. Where the values had no variation with F and values, they were marked as (−).
