eritrin

Eritrin is a pigment found in certain plants, notably in the petals of the flower *Calopogon pulchellus*, commonly known as the Grass Pink orchid. This compound belongs to the class of anthocyanins, which are water-soluble flavonoid pigments responsible for red, purple, and blue colors in many fruits, vegetables, and flowers. Eritrin's specific chemical structure contributes to the pink coloration observed in its natural source. While the precise biological function of eritrin within the plant is not fully understood, it is hypothesized to play a role in attracting pollinators or protecting the plant from environmental stressors. Research into the properties of eritrin is ongoing, with potential applications in natural colorants or as a subject of phytochemical study. The extraction and isolation of eritrin are typically performed using solvent-based methods, allowing for its analysis and investigation in laboratory settings. Its presence is primarily documented within botanical and chemical research contexts.
