Arbutin, yemwenso amadziwika kuti Arbutin, ndi woyera acicular crystal kapena ufa. Masamba otengedwa ku chipatso cha chimbalangondo amatha kuletsa mapangidwe a melanin poletsa ntchito ya Tyrosinase m'thupi, motero amachepetsa kuyika kwa pigment pakhungu, kuchotsa mawanga amtundu ndi mawanga, komanso kukhala ndi bactericidal ndi anti-inflammatory effect. Zogwiritsidwa ntchito makamaka pokonzekera zodzoladzola zapamwamba.
Dzina la Chingerezi: Arbutin
Arbutin imagawidwa kukhala β- Ursolin (Beta arbutin) ndi α- Arbutin (alpha arbutin), α-Arbutin
Kusiyana pakati pa awiriwa:
Ambiri arbutin pamsika ndib-Arbutin, α- Opanga ochepa okha ndi omwe amapanga arbutin, ndipo mtengo wake ndi pafupifupi 8 nthawi zakale. Koma kuyera kwake kumaposa nthawi 15 kuposa zakale.
Kusiyanitsa kwakukulu kwazinthu zakuthupi pakati pa awiriwa ndi kuzungulira kwawo kwa kuwala: α- Zomwe zili mu arbutin zimakhala pafupifupi madigiri 180, pamene β- Arbutin ili pafupi -60.
Arbutin ndi chinthu chachilengedwe chogwira ntchito chochokera ku Viridiplantae. Ndi gawo lopaka khungu lomwe limaphatikizapo "Viridiplantae, chitetezo ndi kudalirika" ndi "decolorization yabwino". Imatha kulowa mwachangu pakhungu, kuletsa bwino ntchito ya Tyrosinase pakhungu, kuletsa mapangidwe a melanin, ndikufulumizitsa kuwonongeka ndi kutulutsa kwa melanin podziphatikiza ndi tyrosinase popanda kukhudza kuchuluka kwa kuchuluka kwa maselo. kuyika kwa pigment pakhungu, kuchotsa mawanga amtundu ndi mawanga, ndipo alibe poizoni, zokwiyitsa, zosagwirizana ndi zina pa Chromatophore. Nthawi yomweyo, imatha kuphanso mabakiteriya ndikuchepetsa kutupa. Ndiwoteteza komanso wothandiza kwambiri pakuyeretsa khungu lodziwika bwino, komanso ndi bwino kuyeretsa khungu ndikuchotsa mawanga azaka za m'ma 2100.
Momwe Mungawonjezere Arbutin pa Njira Yanu Yosamalira Khungu
Mutha kugwiritsa ntchito arbutin mosamala mpaka 2 peresenti yamafuta amaso ndi 0,5 peresenti yamafuta odzola amthupi, akutero Chiu, ndikuwonjezera kuti chopangiracho "ndichotetezeka komanso chocheperako poyerekeza ndi hydroquinone." (Ngakhale kuti hydroquinone yochulukirapo kuposa 1 peresenti yaletsedwa muzodzoladzola ku EU, Japan, Australia, ndi mayiko angapo ku Africa, arbutin ndi yotetezeka pazomwe zili pamwambapa chifukwa hydroquinone imatulutsidwa pang'onopang'ono ndipo khungu silimawonekera kwambiri. za izo nthawi iliyonse, akufotokoza.)
Arbutin ndi chinthu chowala pakhungu chomwe chimalimbana ndi mawanga akuda, hyperpigmentation, ndi zipsera. Ngakhale ili ndi mphamvu zochepa poyerekeza ndi hydroquinone, ili ndi mbiri yachitetezo champhamvu komanso zowopsa zocheperako.
