| 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. |
