Determination of Phenolic Compounds and Bioactive Potential of Plum (<i>Prunus salicina</i>) Peel Extract Obtained by Ultrasound-Assisted Extraction

<div>Cytotoxic effects of plum peel extract (PPE) on cancer cell lines in vitro. (a) Results of MTT cytotoxicity assay showing increase in growth inhibition of DLD-1, HCT-116, MDA-MB-231, and PC3 cells with increasing concentration of PPE. Doxorubicin was used as a positive control. Error bars show standard error of mean of four wells. (b) IC<sub>50</sub> of PPE, values were obtained by nonlinear regression curve fitting of normalized cell survival; error bars represent 95% confidence interval. (c) Phase contrast microscopy, images were obtained after 72 hours of treatment with PPE; scale bar represents 100 <i>μ</i>m.</div>
