Luteolinidin

Luteolinidin is a naturally occurring compound belonging to the anthocyanidin class. Anthocyanidins are water-soluble pigments that can appear red, purple, or blue depending on the pH. Luteolinidin is specifically derived from luteolin, a flavone. Its chemical structure features a flavonoid backbone with specific hydroxyl group substitutions.

This compound is found in various plants, often as part of larger glycosylated molecules called anthocyanins. While not as widely studied as some other anthocyanidins like cyanidin or delphinidin, luteolinidin has been identified in several plant species. Research into its biological activities is ongoing, with some studies exploring its potential antioxidant properties, a common characteristic of flavonoids.

The specific color contribution of luteolinidin to plants is influenced by factors such as pH and the presence of co-pigments. Its extraction and isolation from plant sources can be challenging, contributing to its less frequent occurrence in commercial applications compared to more abundant plant pigments. Further scientific investigation is needed to fully understand its distribution in the plant kingdom and its complete range of physiological effects.
