Peonidin chloride has antioxidant activity. Peonidin has show potent inhibitory and apoptotic effects on cancer cells in vitro, notably metastatic human breast cancer cells.

Purified cyanidin chloride did not inhibit the growth of corn earworm (CEW) larvae at 1000 ppm in insect diet, but purified Peonidin chloride significantly reduced the growth of the larvae at the same concentration. Peonidin has the same structure as cyanidin except that its 3'-hydroxyl group is methylated. In order to confirm these findings, we also tested plant materials that contain cyanidin and peonidin type anthocyanins. We excised colored and white sectors from striped petunia flowers and fed them separately to CEW larvae. After 2 days of feeding, the CEW larvae fed significantly less on the colored sectors compared to the white sectors. The reduction in feeding rates was greater in colored sectors containing peonidin type anthocyanins compared to those containing cyanidin type anthocyanins.
