anthoxanthin

Anthoxanthins are a group of ivory to yellow or orange crystalline pigments found primarily in plants. They are a type of flavonoid, which are non-nitrogenous biological pigments. These pigments are similar to anthocyanins but are derived from flavone or flavonol.123

Anthoxanthins are known for imparting yellow colors, often to flower petals. While their exact physiological functions are not definitively established, they may offer protection against ultraviolet radiation and act as antioxidants. They also play a role in attracting pollinators to flowers and aiding in seed dispersal by animals. Although predominantly found in plants, anthoxanthins have limited occurrence in animals, which obtain them from plant sources.23
