Kev siv

Arbutinbelongs rau hydroquinone glycoside compounds. Nws cov tshuaj lom neeg lub npe yog 4-hydroquinone-alpha-d-glucopyranoside. Nws tshwm sim hauv cov nroj tsuag xws li beberberry thiab bilberry, thiab nws yog cov tshiab tawm ntuj tshiab whitening tej yam yeeb yam tsis muaj kev sib haum xeeb, tsis muaj kev fab tshuaj thiab muaj zog nyob rau ntawm cov tshuaj lom neeg. Muaj ob pawg qauv thiab kev ua haujlwm ua haujlwm hauv cov qauv molecular ntawm arbutin: ib qho yog cov txiaj ntsig zoo, thiab lwm tus yog cov pab pawg phenholrothyl. Alpha-Arbutin nyob hauv lub xeev lub cev ntawm ib tug dawb rau lub teeb grey hmoov thiab yog qhov tseeb soluble hauv dej thiab ethanol.

Alpha-ArbutinMuaj kev kho mob zoo ntawm cov nti tshwm sim los ntawm ultraviolet hlawv, thiab muaj cov tshuaj tiv thaiv zoo, kho thiab cov tshuaj ntxuav hniav dawb. Nws tuaj yeem tiv thaiv kev tsim khoom thiab tso nyiaj ntawm melanin thiab tshem tawm cov hnub nyoog thiab quav hnav.

Txoj kev ntxuav hniav dawb ntawm alpha-arbutin yog kom ua tiav qhov kev tsim ntawm melanin, yog li ua tiav lub me me melanin los ntawm kev ua kom muaj kev loj hlob ntawm lub cev lossis qhov kev qhia ntawm Tyrosinase Gene. Txij li thaum Alpha-arbutin yog qhov ua tau zoo dua thiab muaj kev nyab xeeb ntau cov tshuaj pleev ib ce, muaj ntau cov tshuaj pleev ib ce ua kom zoo nkauj tsis siv beta-arbutin raws li whitening additive. Alpha-arbutin yog tshuaj lom neeg. Zoo ib yam li arbutin, alpha-arbutin tuaj yeem tiv thaiv kev tsim khoom thiab tso nyiaj ntawm melanin thiab tshem tawm cov hnub nyoog thiab quav. Cov kev tshawb fawb pom tau tias Alpha-arbutin tuaj yeem inhibit qhov kev ua ub no ntawm tyrosinase, thiab nws cov nyhuv qis, thiab nws cov nyhuv loj ntawm tyrosinase yog qhov zoo dua li arbutin. Alpha-Arbutin tuaj yeem siv los ua cov neeg ntxuav hniav dawb hauv cov tshuaj pleev ib ce.
