| Nchịkọta | arbutin bụ hydroquinone glycoside compound, aha kemịkal maka 4-hydroxyphenyl-d-glucopyranoside (y), dị na mkpụrụ osisi, bilberry na osisi ndị ọzọ, bụ ihe ọhụrụ na-adịghị ewe iwe, na-enweghị ihe nfụkasị ahụ, ihe na-arụ ọrụ na-acha ọcha eke na-arụ ọrụ siri ike. Arbutin nwere akụkụ abụọ na-arụ ọrụ na-arụ ọrụ na nhazi ya: otu bụ ihe fọdụrụnụ nke glucose; Nke ọzọ bụ otu phenolic hydroxyl. Ọnọdụ anụ ahụ nke α-arbutin na-egosi dị ka ọcha na-acha ntụ ntụ ntụ, nke na-agbaze na mmiri na ethanol. |
| arụmọrụ | α-arbutin nwere mmetụta ọgwụgwọ ka mma na scars nke UV Burns kpatara, nwere mmetụta mgbochi mkpali ka mma, nrụzi na ịcha ọcha. Nwere ike igbochi mmepụta na ntinye nke melanin, wepụ ntụpọ na freckles. |
| usoro nke ime ihe | Usoro ịcha ọcha nke α-arbutin na-egbochi ọrụ tyrosinase ozugbo, si otú a na-ebelata mmepụta nke melanin, kama ibelata mmepụta melanin site na igbochi uto cell ma ọ bụ okwu mkpụrụ ndụ tyrosinase. Dị ka α-Arbutin bụ ihe na-arụ ọrụ nke ọma na nke dị nchebe karị, ọtụtụ ụlọ ọrụ ịchọ mma n'ụlọ na ná mba ọzọ anabatala α-arbutin kama β-arbutin dị ka ihe mgbakwunye na-acha ọcha. |
| Ngwa | alpha-Arbutin bụ kemịkal nke yiri arbutin, nwere ike igbochi mmepụta na ntinye nke melanin, wepụ ntụpọ na ntụpọ. Nsonaazụ gosiri na arbutin nwere ike igbochi ọrụ tyrosinase na ntinye uche dị ntakịrị, yana mmetụta mgbochi ya na tyrosinase dị mma karịa nke arbutin. Enwere ike iji alfa-arbutin mee ihe dị ka ihe na-acha ọcha na ihe ịchọ mma. |
| ọcha na njirimara | A na-ebu ụzọ wepụ ihe nlele ahụ nwetara site na mmeghachi omume ya na ethyl acetate, wee wepụ ya na n-butanol, a na-anakọta ihe nlele ahụ site na evaporation na rotary evaporator na centrifuged. A na-enyocha ihe dị elu site na HPLC wee jiri ya tụnyere HPLC chromatogram nke α-arbutin, ma atụnyere ihe nlele na α-arbutin nwere otu oge njide, yana ma ihe nlele ahụ nwere α-Arbutin bụ nke a na-ebute ụzọ. Achọpụtara ngwaahịa ahụ mgbe mmịpụta na ịdị ọcha site na ụdị ion dị mma nke LC-ESI-MS/MS. Site n'ịtụle mkpokọta molekụla nke mkpụrụ osisi α-bear na nha molekul nke ọkọlọtọ α-arbutin, enwere ike ikpebi ma ngwaahịa ahụ ọ bụ α-arbutin. |
| Ojiji | α-arbutin nwere ike igbochi ọrụ tyrosinase na ntinye uche dị ntakịrị, mmetụta mgbochi ya na tyrosinase dị mma karịa nke arbutin. |
