Inzululwazi | mhlophe isiphumo izimonyo izinto ekrwada — arbutin Icandelo lokuqala

NgoFebruwari 2023, i-European Union Scientific Committee for Consumer Safety (SCCS) yakhupha uluvo lokugqibela malunga nokhuseleko lwabathengi.α-arbutinkwayeβ-arbutinkwizinto zokuthambisa, kunye nesiphumo esimhlophe sesithako seenkwenkwezi i-arbutin kwakhona yabangela inkxalabo kushishino.

Yintoni i-arbutin?

I-Arbutin (Arbutin), eyaziwa ngokuba yi-arbutin, igama lekhemikhali i-4-hydroxyphenyl-D-glucopyranoside, ubunzima bemolekyuli yi-272.25, yi-glycoside yendalo evela kwizityalo eziluhlaza, izityalo ezininzi ezomisa umkhenkce, njengengqolowa, ipere, i-rhododendraceae ithwala iziqhamo ezityebileyo. kwizisombululo, iikristale ezimhlophe aciculate okanye umgubo, Inyibilika emanzini ashushu, i-methanol, i-ethanol kunye nepropylene glycol, ipropylene glycol, i-ether, i-chloroform, i-petroleum ether kunye nezinye izinyibilikisi.

I-Arbutin inokwahlulwa ibe yi-α yodidi kunye nohlobo lwe-β ngokwesakhiwo esahlukileyo. I-α-arbutin ibizwa ngokuba yi-4-hydroxyphenyl-α-D-glucopyranoside, kwaye i-β-arbutin ibizwa ngokuba yi-4-hydroxyphenyl-β-D-glucopyranoside. I-Alpha-arbutin yi-isomer eyahlukileyo ye-β-arbutin, kwaye i-glucoside bond yayo ichasene nendawo kunye ne-β-arbutin (bona umfanekiso).
