pelargonidin

Pelargonidin is a naturally occurring **anthocyanidin**—a plant pigment notably responsible for orange to red colors in various flowers and fruits. It belongs to the flavonoid class, specifically 7-hydroxyflavonoids, and contains hydroxy groups at the 3, 5, 7, and 4' positions of the flavylium backbone[1][5][7]. **Pelargonidin is primarily found in red geraniums, and fruits such as strawberries, black raspberries, radishes, and sour cherries**[1][7]. It serves as a plant metabolite with notable **antioxidant properties** and has been studied for potential antidiabetic and anticancer effects, mainly through radical scavenging and inhibition of reactive oxygen species, though it is not an approved pharmaceutical drug[2]. Its mechanism of action is primarily related to non-specific antioxidant activity and possibly the inhibition of enzymes like nitric oxide synthase (NOS)[2].
