Best Alpha Arbutin Manufacturers | Supplier with Wholesale Price - Greenway Biotech

Arbutin is a hydroquinone glycoside compound, the chemical name is 4-Hydroquinone-alpha-D-glucopyranoside, which exists in bearberry, bilberry and other plants. It is a new non-irritating, non-allergic and highly compatible natural whitening active substance from Chemicalbook. There are two structural and functional functional groups in the molecular structure of arbutin: one is a glucose residue; the other is a phenolic hydroxyl group. The physical state of α-arbutin is white to light gray powder, which is easily soluble in water and ethanol.

Effect	α-Arbutin has a good therapeutic effect on scars caused by ultraviolet burns, and has good anti-inflammatory, repairing and whitening effects. Can inhibit the production and deposition of melanin, remove pigmentation and freckles.
Mechanism	The whitening mechanism of α-arbutin directly inhibits the activity of tyrosinase, thereby reducing the production of melanin, rather than reducing the production of melanin by inhibiting cell growth or tyrosinase gene expression. Since α-arbutin is a more efficient and safer whitening active substance, many cosmetic companies at home and abroad have used α-arbutin instead of β-arbutin as a whitening additive.
Application	Alpha-arbutin is a chemical, similar to arbutin, that inhibits the production and deposition of melanin, and removes pigmentation and freckles. Studies have shown that arbutin can inhibit the activity of tyrosinase at a relatively low concentration, and its inhibitory effect on tyrosinase is better than that of arbutin. Alpha-arbutin can be used in cosmetics as a whitening agent.
Purification and Identification	The samples obtained by the reaction were first extracted with ethyl acetate, then extracted with n-butanol, evaporated to dryness by a rotary evaporator, and then centrifuged. The supernatant was analyzed by HPLC and compared with α-arbutin standard Compare the HPLC chromatogram of the product, compare whether the sample and α-arbutin have the same retention time of Chemicalbook, and preliminarily infer whether the sample contains α-arbutin. The product after extraction and purification was identified by the positive ion mode of LC-ESI-MS/MS. The relative molecular mass of the α-arbutin product is compared with the relative molecular weight of the α-arbutin standard to determine whether the product is α-arbutin.
