Anthraquinones are organic compounds known for their vibrant colors and presence in a variety of natural sources. These compounds, found in plants, fungi, and some insects, are often used as dyes and pigments. Anthraquinones have also been studied for their potential medicinal properties, particularly as laxatives and antimicrobial agents. They are key components in traditional herbal remedies and are employed in some modern pharmaceuticals. Additionally, anthraquinones are of interest in the study of photophysics and photochemistry due to their ability to absorb and emit visible light.
