Here is the product details of Arbutin (CAS: 497-76-7):
- Basic Information
- Chemical Name: 4 - Hydroxyphenyl β - D - glucopyranoside.
- Molecular Formula: C₁₂H₁₆O₇.
- Molecular Weight: 272.25.
- Alias: β - Arbutin, p - Arbutin, Uvasol, Ursin, etc.
- Physical and Chemical Properties
- Appearance: White solid or white needle - like crystals.
- Solubility: Soluble in hot water, methanol, ethanol, propylene glycol and glycerol aqueous solution, insoluble in ether, chloroform, petroleum ether and other solvents.
- Melting Point: 198 - 201℃.
- Density: 1.556g/cm³.
- Refractive Index: 1.65.
- Stability: Stable, hygroscopic, should be stored under dry nitrogen.
- Extraction and Synthesis
- Extraction: It can be extracted from various plants such as Arctostaphylos uva - ursi, Vaccinium bracteatum, and Pyrus leaves. Through separation and purification methods such as organic solvent extraction and column chromatography, arbutin can be obtained.
- Synthesis: It can be synthesized by chemical methods. It can also be obtained by the enzyme - conversion method using hydroquinone and glucose under the catalysis of β - glycosidase.
- Pharmacological Effects
- Inhibiting Melanin: It can inhibit the activity of tyrosinase, block the synthesis of dopa and dopaquinone, curb the growth of melanin, reduce melanin deposition, and remove age spots and freckles.
- Analgesic, Anti - inflammatory and Antibacterial: It can be used for anti - inflammation and anti - ulcer, and can inhibit insulin degradation. Hydroquinone produced by oral hydrolysis has a bactericidal effect, which can be used to treat urinary tract infections and intestinal anti - inflammation.
- Antitussive, Expectorant and Anti - Asthmatic: It has certain antitussive, expectorant and anti - asthmatic effects. It can increase tracheal secretion, prolong the latent period of ammonia - water induced cough, reduce the number of coughs, and increase the excretion of phenol red in the trachea.
- Application Fields
- Cosmetics: As an effective competitive inhibitor of tyrosinase, it is commonly used as a whitening raw material in high - end cosmetics. It can reduce melanin production and achieve the effect of whitening skin.
- Pharmaceuticals: It has a low - toxicity antitussive effect and has a high selectivity for the central nervous system. It can be used as a urinary disinfectant, a new type of burn medicine, a cryoprotectant in cartilage bone transplantation, a decolorizing agent, a raw material for intestinal anti - inflammatory drugs, etc. It can also be used to treat tracheitis, infectious urinary system diseases, allergies, skin diseases and inflammatory diseases.
- Safety Considerations: The Scientific Committee on Consumer Safety of the European Union stipulates that the maximum safe use concentration of β - arbutin in facial creams is 7%. When the addition amount of β - arbutin in cosmetics is greater than 3%, it will significantly inhibit or damage cell growth, resulting in cytotoxicity.
