Ultrasonic Extraction of Phenolic Compounds from Eggplant Peel and Formulation of Eggplant Peel Extract-Enriched Ice-Cream

Quantification of cytotoxic effects of the eggplant peel extract on human cancer cell lines in vitro. (a) Results of MTT cytotoxicity assay showing reduction in survival of MDA-MB-231, DLD-1, HCT-116, and PC3 cells. Cells were treated with different concentrations of the eggplant peel extract for 72 hours, and data shown were normalized to zero drug controls. Doxorubicin was used as a positive-control cytotoxic substance. Error bars show the standard error of the mean of four wells, and results shown are representative of three independent repeats. (b) IC₅₀ of eggplant peel extract treatment in cancer cell lines. Data shown were obtained by nonlinear regression curve fitting of normalized cell survival, and error bars represent 95% confidence interval. (c) Assessment of morphological changes in different cancer cells after 72 hours of treatment with increasing concentration of the eggplant peel extract. The scale bar represents 100 micrometers, and all images were captured at the same magnification.
