I te Hui-tanguru 2023, i tukuna e te Komiti Putaiao a te Kotahitanga o Europi mo te Haumaru Kaihoko (SCCS) he whakaaro whakamutunga mo te haumaru oα-arbutinaβ-arbutini roto i nga whakapaipai, me te maatanga o te arbutin whakauru whetu i puta ano te awangawanga i roto i te umanga.
He aha te arbutin?
Ko Arbutin (Arbutin), e mohiotia ana ko te arbutin, ingoa matū 4-hydroxyphenyl-D-glucopyranoside, ko te taumaha molecular whanaunga ko 272.25, he glycoside taiao mai i nga tipu matomato, he maha nga tipu whakamaroke-tio, penei i te witi, te pear, te rhododendraceae e whai hua ana. i roto i nga whakarewa, nga tioata aciculate ma, te paura ranei, Ka whakarewahia i roto i te wai wera, te mewaro, te waihano me te propylene glycol, te propylene glycol, te kore e rewa i te etera, te chloroform, te hinu etera me etahi atu whakarewa.
Ka taea te wehewehe i te Arbutin ki te momo α me te momo β kia rite ki te hanganga rereke. Ko te α-arbutin he matū e kiia ana ko te 4-hydroxyphenyl-α-D-glucopyranoside, ko te β-arbutin e kiia ana ko te 4-hydroxyphenyl-β-D-glucopyranoside. Ko te Arepa-arbutin he imaoma rereke o te β-arbutin, a ko tana here glucoside he mokowhiti ki tera o te β-arbutin (tirohia te ahua).
