Imikoreshereze
ArbutinIgize hydroquinone glycoside. Izina ryayo ry'ibinyabutabire ni 4-Hydroquinone-alpha-D-glucopyranoside. Iboneka mu bimera nka bearberry na bilberry, kandi ni ikintu gishya gishya kivuka mu buryo bw'umwimerere kitagira uburibwe, nta ubwivumbure kandi gihuye cyane na Chemicalbook. Hari amatsinda abiri y'imikorere n'imikorere mu miterere ya arbutin: rimwe ni ibisigazwa bya glucose, irindi ni itsinda rya phenolic hydroxyl. Alpha-arbutin iri mu buryo bw'ifu y'umweru kugeza ku ibara ryoroheje kandi irashongesha mu mazi na ethanol.
Alpha-arbutinIgira ingaruka nziza ku nkovu ziterwa no gutwika hakoreshejwe imirasire ya ultraviolet, kandi irwanya ububyimbirwe, gusana no kweza. Ishobora kubuza ikorwa n'ishyirwa rya melanin no gukuraho ibizinga n'uduheri.
Uburyo bwo kugabanya umweru bwa alpha-arbutin ni ukubuza imikorere ya tyrosinase, bityo bikagabanya ikorwa rya melanin, aho kugera ku ntego yo kugabanya ikorwa rya melanin binyuze mu kubuza gukura kw'uturemangingo cyangwa kugaragaza gene ya tyrosinase. Kubera ko alpha-arbutin ari ikintu gikora neza kandi gitekanye cyo kugabanya umweru, amasosiyete menshi yo mu gihugu no mu mahanga yamaze gukoresha alpha-arbutin aho gukoresha beta-arbutin nk'inyongera mu kugabanya umweru. Alpha-arbutin ni ikintu kigizwe n'ibinyabutabire. Kimwe na arbutin, alpha-arbutin ishobora kubuza ikorwa n'ishyirwa rya melanin no gukuraho utudomo n'uduheri. Ubushakashatsi bwagaragaje ko alpha-arbutin ishobora kubuza imikorere ya tyrosinase ku rugero ruto, kandi ingaruka zayo zo kubuza tyrosinase ni nziza kuruta iya arbutin. Alpha-arbutin ishobora gukoreshwa nk'ikintu gikora mu kugabanya umweru mu kwisiga.
Gupakira no Kohereza
25KG/Ingoma cyangwa nk'uko umukiriya abikeneye.
Ni iy'ibicuruzwa rusange kandi ishobora gutangwa binyuze mu nyanja no mu kirere
Bika kandi ubibike
Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.
