Mawu Oyamba
β-Arbutin imagwiritsidwa ntchito ngati chopangira choyera powongolera kutulutsa kwa ma melanin pigment, omwe ndi zinthu zomwe zimayambitsa kusinthika ndi mawanga.
Amadziwika kuti ndi mankhwala omwe ali mu zitsamba za ericaceous zotchedwa bearberry leaf.Kutayika kwamtundu ndi makwinya kumachitika chifukwa cha okosijeni wosunthika wopangidwa pakhungu poyang'aniridwa ndi UV pakuwala kwa dzuwa, kupsinjika, kuipitsidwa kwamlengalenga, ndi zina zambiri, zomwe zimayambitsa tyrosinase ndipo enzyme yomwe idakhazikitsidwa imalimbikitsa kutembenuka kwa tyrosine mu melanocytes (maselo a pigment) kukhala ma melanin pigments.β-Arbutin akuti akuwonetsa zoyera pochepetsa kupanga ma melanin pigment pogwira ntchito mwachindunji pa tyrosinase mu melanocytes.
