Kugwiritsa ntchito
Arbutinndi a hydroquinone glycoside glycoside. Dzina lake la mankhwala ndi 4-hydroquinone-alpha - D-Glucopyranide. Imakhalapo muzomera monga bearrriry ndi bilberi, ndipo ndikuli bwino chifukwa chofuula osakwiya, osagwirizana ndi ziwonetsero zamakebook. Pali magulu awiri ogwira ntchito ndi ogwira ntchito moleckal a Arbutin: imodzi ndi zotsalira za shuga, ndipo inayo ndi gulu la phenocrolic hydroxyl. Alpha-Arbutin ali mu thupi loyera kunyezimira imvi ndipo imasungunuka m'madzi ndi Mowa.
Alpha-ArbutinAli ndi achire bwino pa zipsera zoyambitsidwa ndi ultraviolet kuyaka, ndipo ali ndi anti-kutupa, kukonza ndi kuyerekeza ndi zoyera. Zimatha kulepheretsa kupanga ndi kuwonongeka kwa melanin ndikuchotsa mawanga ndi ma freckles.
Njira yoyera ya alpha-Arbutin ikulepheretsa mwachindunji ntchito ya truskinase, poyerekeza ndi kupanga kwa melanin, m'malo mongochepetsa mphamvu ya kukula kwa ma cell kapena kuwonetsa kwa generacidase. Popeza alpha-Arbutin ndiogwira ntchito bwino kwambiri komanso yoyera yoyera, yamakampani ambiri odzikongoletsera adagwiritsa ntchito albutin m'malo mwa beta-arbutin. Alpha-Arbutin ndi mankhwala opangira mankhwala. Zofanana ndi Arbutin, Alpha-Arbutin imatha kuletsa kupanga ndi kuwonongeka kwa melanin ndikuchotsa mawanga ndi ma freckles. Kafukufuku wawonetsa kuti alfa-arbutin amatha kuletsa ntchito ya TrusrosAse pamtundu wotsika, ndipo zoletsa zake za ku Terrofinase ndiyabwino kuposa a Arbutin. Alpha-Arbutin imatha kugwiritsidwa ntchito ngati yoyera yoyera muzodzola.

25kg / Drum kapena monga zofunikira zamakasitomala.
Ndi wa zinthu wamba ndipo amatha kupulumutsa ndi nyanja ndi mpweya
Pitilizani ndikusunga
Moyo wa alumali: Mwezi 24 kuyambira tsiku lopanga mu phukusi lokhazikika losagwirizana ndi dzuwa louma, madzi.
Chosokoneza chosungira, kuyanika kwa kutentha kochepa, kupatulidwa ndi oxidants, ma acid.
