Alpha-Arbutin

Sharaxaad Gaaban:

Alpha-Arbutin (4-Hydroxyphenyl-±-D-glucopyranoside) waa saafi ah, biyo milmay, walax firfircoon biosynthetic. Alpha-Arbutin wuxuu xannibaa isku-darka melanin ee epidermal isagoo xakameynaya oksaydhka enzymatic ee Tyrosine iyo Dopa. Arbutin wuxuu u muuqdaa inuu leeyahay waxyeelooyin ka yar kan hydroquinone marka loo eego xaddi la mid ah - malaha sababtoo ah si tartiib tartiib ah u sii deynaya. Waa habka ugu waxtarka badan, ugu dhakhsaha badan iyo badbaadada leh ee kor loogu qaadayo iftiiminta maqaarka iyo midabka maqaarka ee dhammaan noocyada maqaarka. Alpha-Arbutin sidoo kale waxa ay yaraynaysaa dhibcooyinka beerka waxayna buuxisaa dhammaan shuruudaha maqaarka ifaya ee casriga ah iyo badeecada maqaarka.

Alpha-Arbutin waa glycoside biosynthetic ah oo leh sifooyin iftiin maqaarka ah oo aad u fiican oo qumman xitaa midabka maqaarka. Waxay awood u leedahay inay si wax ku ool ah u joojiso isku-dhafka melanin iyadoo la xakameynayo tyrosinase, saameyntani waa mid la gaari karo xitaa marka aad u yar tahay. AlfaArbuutin Waxay muujisaa xannibaadda tyrosinase ee cajiibka ah waxayna sagaal jeer ka waxtar badan tahay Beta-Arbutin. Qiimaha IC50 aad u hooseeya ayaa muujinaya awoodda Alpha-Arbutin. Waxtarka aadka u wanaagsan ee Alphar-Arbutin waxa sabab u ah xidhiidhka qumman ee ay la leedahay goobta firfircoon ee tyrosinase. Alpha-Arbutin waa biyo milmay oo si fudud loogu daraa wejiga biyaha ee qaababka qurxinta. Waa xasiloon liddi ku ah hydrolysis sida lagu tijaabiyay qiyaasta pH ee u dhaxaysa 3.5 - 6.6. Xoojinta la soo jeediyay: 0.2% marka lagu qaabeeyay kor u qaade ama wax galinta, haddii kale ilaa 2%. Halbeegyada Farsamo ee Muhiimka ah:
