Naringin Powder is a dihydroflavonoid, pale yellow powder. The content of crystal water and its melting point in pure naringin vary according to the crystallization and drying methods. The naringin molecule obtained by crystallization with water as a solvent contains 6 to 8 crystal waters, with a melting point of 83 ° C; and drying at 110 ° C. The naringin molecule obtained after reaching constant weight contains 2 crystal waters, and its melting point rises to 171°C.
China is the world's largest pomelo-producing country. According to the United Nations Food and Agriculture Organization (FAO) statistics, in 2008, China's pomelo production was about 570,000 tons, and it showed a further rapid growth trend. Studies have shown that naringin (Naringin, CAS 10236-47-2), which is mainly contained in pomelo peel, is a class of natural flavonoids (Flavonoids), which mainly exist in the peels of pomelo, grapefruit, lime and their variants. Naringin is widely used in medicine, food science, chemistry, etc.
Naringin, also known as naringin and citrus glycosides, is a light yellow dihydroflavonoid compound extracted from the immature or near-ripe dried peels of Rutaceae citrus plants pomelo and grapefruit. It is a natural flavonoid. compound.
The chemical formula of naringin is 4,5,7-trihydroxyflavanone-7-rhamnoside, and its chemical structure was first elucidated by Asahina and Inubuse in 1928. Because there is no conjugation between its A ring and B ring, it has a strong ultraviolet absorption peak at 282 nm, which makes naringin have a variety of pharmacological activities, such as blood lipid regulation, anti-diabetic, neuroprotection, etc.
The Benefit: Naringin has anti-inflammatory, anti-viral, anti-cancer, anti-mutation, anti-allergic, anti-ulcer, analgesic, hypotensive activities, can lower blood cholesterol, reduce the formation of thrombus, improve local microcirculation and nutrient supply, can be used In production prevention and treatment of cardiovascular and cerebrovascular diseases. The derived neohesperidin, the dihydrochalcone neohesperidin produced by hydrogenation, has a sweetness equivalent to 1500 times that of sucrose.
Application: As a natural pigment, modifier and bittering agent, widely used in food and beverage production, and also used to synthesize non-toxic, low-energy, high-sweet naringin dihydrochalcone and neohesperidin dihydrogen Raw materials for chalcone. In addition, it has antioxidant properties and can be used in other fields.
