What is Delphinidin?

Delphinidin, classified as a flavonoid anthocyanidin, represents a vital component of the plant kingdom's pigmentation palette, responsible for imparting vibrant blue to violet hues in various fruits, vegetables, and flowers. Structurally, delphinidin features a core C6-C3-C6 skeleton, characterized by two aromatic rings (A and B) connected by a heterocyclic ring (C), adorned with hydroxyl (-OH) and methoxy (-OCH3) groups at specific positions.

Beyond its role in pigmentation, delphinidin exhibits a plethora of biological activities, ranging from antioxidant and anti-inflammatory properties to potential anticancer effects. Research suggests its involvement in mitigating oxidative stress, scavenging free radicals, and modulating cellular signaling pathways, thereby conferring protective effects against various chronic diseases.
