The study on Hesperidin is recently very hot in the fields of food, medicine and personal care product industries. Hesperetin flavone mainly exists in natural plant Fructus Aurantii Immmaturus, Pericarpium citri reticulate, Citrus peel, and so on. It has various physiological activities: antibiotic, anti-inflammation, antiviral; prevention of cardiovascular disease; relaxant effects on gastrointestinal smooth muscles; reinforcement of Vitamin C; anti-oxidization of free radicals; inhibitor of central nervous system; reducing cholesterol; improvement of skin quality; anti-Osteoporosis; anti-cancer, and others. This paper studies the main functions of hesperidin, the main materials for extraction of hesperidin, and the extraction and purification technologies. The extraction methods include boil water extraction; alkali-extraction and acid-precipitation; alcohol extraction and acid precipitation; water extraction and resin adsorption. By using property modification technology, one could prepare water soluble hesperidin, hesperetin, persicogenin, diosmin, diosmetin, methylhesperidin, hesperidindihydrochalcone, luteolin, eriodictyol, orobol, neohesperidin flavonoid, and others, which will help the study on hesperidin flavonoid.
