Alpha-Arbutin uye Beta-Arbutin zvinhu zviviri zvakajairika zvekuchena zvimisikidzo. Vane mimwe misiyano muchimiro uye zvivakwa, sezvinotevera:
Chimiro:
Zita remakemikari ye α-arbutin inonzi 4-hydroxybenzaldehyde-D-glucoside, iyo inoumbwa nekubatanidza benzaldehyde uye glucose molecules kuburikidza neboka realdehyde uye boka rehydroxyl. Zita remakemikari ye β-arbutin inonzi β-D-glucoside ether benzaldehyde, iyo inoumbwa kubva kuglucose uye benzaldehyde molecules kuburikidza nekubatana kweglucose uye aldehyde mapoka.
Optical isomers:
Alpha arbutin: Alpha arbutin ndeyeD-isomer, kureva kuti, ine hunhu hwekurudyi.
β-Arbutin ndeyeD-isomer kana isiri-optically inoshanda fomu.
Whitening effect:
Alpha Arbutin: Alpha Arbutin ine simba rakasimba rekuchena, inogona kuvharidzira basa re tyrosinase, kuderedza kugadzirwa kwe melanin, nokudaro kuderedza pigmentation uye manheru ganda toni. Beta arbutin: Beta arbutin zvakare ine imwe chena maitiro, asi kana ichienzaniswa nealpha arbutin, kuchena kwayo haina simba.
Kugadzikana:
Alpha Arbutin:
Alpha arbutin ine kugadzikana kwakanaka mumatrices ane aqueous uye ane mafuta uye haisi nyore kukanganiswa nechiedza, kupisa uye pH kukosha. Kuenzaniswa ne α-arbutin, β-arbutin inonyanya kukanganisa kuora uye kukundikana mune mamwe mamiriro.
Pakazara, pane misiyano pakati pe α-arbutin uye β-arbutin maererano nechimiro, optical isomers, whitening effect uye kugadzikana. Alpha arbutin ine simba rakasimba rekuchena uye kugadzikana kwakanaka, nepo beta arbutin ine kushaya simba kwekuchena mhedzisiro uye kusagadzikana kwakashata. Izvo chaizvo zvinoshandiswa zvinoshandiswa zvinoenderana nezvinodiwa uye zvinodiwa zvechigadzirwa.
Solubility:
Alpha Arbutin: Alpha Arbutin ine yakanyanya solubility uye inogona kunyungudika muzvinonyungudutsa zvakaita semvura uye ethanol. Iko kunyungudika kwebeta arbutin kwakadzikira, zvishoma kuipa kupfuura alpha arbutin.
Safety:
Alpha arbutin inoonekwa sechinhu chakachengeteka chekuchenesa ganda, isinganyanyi kushungurudza ganda uye yakakodzera vanhu vane ganda rakasiyana. Beta arbutin zvakare yakachengetedzeka, asi mune dzimwe nguva inogona kukonzera kutsvuka kweganda kana kusawirirana, kunyanya kana ichishandiswa pakakwirira kana paganda rinopfakanyika.
Muzvizoro uye zvigadzirwa zvekuchengetedza ganda, alpha uye beta arbutin zvinowanzonyorwa zvakajeka sezvisanganiswa mufomula. Naizvozvo, iwe unogona kuona kuti ndezvipi zvinongedzo zvinoshandiswa muchigadzirwa nekutarisa rondedzero yechigadzirwa kana kubvunza mhando kana mugadziri.
Izvo zvinofanirwa kucherechedzwa kuti ingave iri alpha arbutin kana beta arbutin, kuchengetedzeka kwayo uye kushanda kwayo kunoenderana neiyo chaiyo chigadzirwa formula uye nzira yekushandisa. Paunosarudza zvigadzirwa zvekushandisa, zviri nani kusarudza zvigadzirwa zvinoenderana nerudzi rweganda rako uye zvaunoda.
