Kupu Whakataki
Ka whakamahia te β-Arbutin hei whakauru ma mo te whakahaere i te whakangao o te melanin pigments, he matū e huri ana te tae me te wiwi.
E mohiotia ana he matū kei roto i nga otaota ericaceous e kiia nei ko te rau bearberry.Ka puta te paheketanga me te pahekeheke na te hāora tauhohe ka puta i roto i te kiri ma te pa ki te UV i te ra o te ra, te ahotea, te parahanga o te hau, me era atu, e whakahooho ana i te tyrosinase me te enzyme whakahohe e whakatairanga ana i te hurihanga o te tyrosine i roto i nga melanocytes (nga pūtau poaka) ki te melanin pigments.E kiia ana ko te β-Arbutin te whakaatu i nga paanga ma te whakaiti i te hanga o te melanin pigments ma te mahi tika ki te tyrosinase i roto i nga melanocytes.
