Peppers are rich in health‐promoting phytochemicals, which are involved in the defense mechanisms against cancer. To select a lead variety of pepper with anti‐proliferative activity against colon cancer cells and liver cancer cells, high antioxidant activity, and high concentrations of capsaicin, flavonoids, and phenolics, we compared these attributes in nine different pepper accessions belonging to Capsicum annuum and C chinense . Quality parameters such as weight loss and total soluble solids content were tested as well. The different parameters were determined immediately after harvest and after prolonged storage and marketing simulation. A significant variation of these traits was detected among the accessions. C. chinense line 1745, had the highest antioxidant activity, the highest levels of capsaicin and flavonoids, a high and specific anti‐cancer activity, and the lowest weight loss level during post‐harvest storage. It is proposed that line 1745 has potential for use as a source for health‐promoting traits and should be further evaluated for use as a nutraceutical for the prevention and treatment of colon and liver cancers.
