Advances in Flavonoid Research: Sources, Biological Activities, and Developmental Prospectives Flavonoids are a class of natural compounds with diverse pharmacological activities, found in plants and used in medicine and food. They are synthesized through various pathways, including plant extraction, chemical synthesis, and biosynthesis. Flavonoids have been shown to have antioxidant, anti-inflammatory, anti-tumor, and anti-diabetic effects, among others. They are also used in drug delivery systems to improve their solubility and bioavailability. Flavonoids are found in various plants, including Lamiaceae, Acanthaceae, and Ginkgoaceae, and are used in the treatment of infectious and non-communicable diseases. Flavonoids can be extracted from plants using various methods, including solvent extraction, ultrasonic extraction, and chemical synthesis. They can also be modified through chemical methods to enhance their biological activities. Flavonoids are also produced by endophytic fungi, and their biosynthesis pathways have been studied. Flavonoids have been shown to have therapeutic effects on various diseases, including cardiovascular diseases, diabetes, and bacterial infections. They are also used in the treatment of liver diseases and pulmonary fibrosis. Flavonoids have a wide range of biological activities and are an important area of research in natural medicine.Advances in Flavonoid Research: Sources, Biological Activities, and Developmental Prospectives Flavonoids are a class of natural compounds with diverse pharmacological activities, found in plants and used in medicine and food.
