Figure 4.
The cell proliferation inhibitory activity of the P. frutescens leave extract and its fractions. (A) The inhibition ratio of HepG2 cell proliferation incubated with different concentrations of samples; (B) the IC50 values of different samples for HepG2 cell proliferation inhibition; (C) the inhibition ratio of MCF-7 cell proliferation incubated with different concentrations of samples; (D) the IC50 values of different samples for MCF-7 cell proliferation inhibition. ND = not detected; CE = crude extract; PE = petroleum ether fraction; CF = chloroform fraction; EtOAc = ethyl acetate fraction; n-BuOH = n-butanol fraction; AQ = aqueous phase residue. Bars with different letters indicate a significant difference (p < 0.05).
