Effects of the seven components isolated from CPWE on the proliferation of four tumor cells. (a) and (b), effect of the seven components (20, 40, 80, and 160 μM) on MCF-7 cell viability at 24 and 48 h. (c) and (d), effect of the seven components on MDA-MB-231 cell viability at 24 and 48 h. (e) and (f), effect of the seven components on A549 cell viability at 24 and 48 h. (g) and (h), effect of the seven components on viability of HeLa cell viability at 24 and 48 h. (i) and (j), effect of crude CPWE on proliferation of four tumor cells. Cell viability was tested by SRB assay and illustrated in column figures (, versus control, ). Data are means ± SEM.
