<p><i>a. Cytotoxicity effect of various concentrations of Plumbagin on
HCT15 cells</i>. Dose dependent cytotoxicity effects of
Plumbagin on HCT15 cells were represented in the above graph. HCT15
cells were more sensitive to plumbagin as IC<sub>50</sub> at 24 hours
was 22.5 µM. All the experiments were done in triplicates and
expressed as the mean ± SD. Significance is indicated as
*<i>p<0.001</i>. <i>b. Cytotoxicity effect of
various concentrations of Plumbagin on HT29 cells</i>. Dose
dependent cytotoxicity effects of Plumbagin on HT29 cells were
represented in the above graph. HT29 cells were more sensitive to
plumbagin as IC<sub>50</sub> at 24 hours was 62.5 µM. All the
experiments were done in triplicates and expressed as the mean ±
SD. Significance is indicated as *<i>p<0.001</i>.
<i>c. Cytotoxicity effect of various concentrations of
Plumbagin on PBMC cells</i>. Dose dependent cytotoxicity
effects of Plumbagin on PBMC cells were represented in the above graph.
PBMC cells were resistance to plumbagin induced cytotoxicity even at 100
µM concentration. All the experiments were done in triplicates and
expressed as the mean ± SD. Significance is indicated as
*<i>p<0.001</i>.</p
