Qhov sib txawv tseem ceeb ntawm arbutin thiab alpha arbutin yog tias arbutin yog glycosylated hydroquinone uas inhibit tyrosinase, tiv thaiv kev tsim ntawm melanin, thaum alpha arbutin yog ib qho ntawm ob hom arbutin tau los ntawm nplooj qhuav ntawm cov nroj tsuag xws li blueberry thiab cranberry thiab yog ntau resistant rau tshav kub, qhia ntau lub teeb stability thiab siab dej solubility zog.
Cov xim ntawm daim tawv nqaij nyob ntawm qhov muaj melanin tam sim no. Qhov no yog khaws cia nyob rau hauv melanocytes ntawm daim tawv nqaij, uas yog stimulated rau secretion los ntawm ib tug enzyme hu ua tyrosinase. Thaum raug tshav ntuj, UV tam sim no nyob rau hauv tshav ntuj activates tyrosinase, yog li ua rau lub secretion ntawm melanin los ntawm melanocytes. Arbutin, uas muaj glycosylated hydroquinone, inhibits tyrosinase thiab tiv thaiv kev tsim ntawm melanin. Yog li ntawd, nws ua haujlwm raws li daim tawv nqaij-lightening tus neeg sawv cev. Ob hom arbutin yog alpha arbutin thiab beta arbutin.
YArbutin yog dab tsi?
Arbutin yog hom glycosylated hydroquinone uas inhibits tyrosinase thiab tiv thaiv kev tsim ntawm melanin. Arbutin yog ib qho tshuaj siv hauv kev lag luam tshuaj pleev ib ce ua tus neeg saib xyuas tawv nqaij. Muaj ob hom arbutin: alpha arbutin thiab beta arbutin. Beta arbutin muaj cov dej solubility tsawg, kub tsis kam, thiab lub teeb ruaj khov thaum piv rau alpha arbutin.
Daim duab 01: Arbutin
Natural arbutin muaj nyob rau hauv bearberries. Thaum muab rho tawm los ntawm bearberries, ntuj arbutin yog kim dua li cov khoom xyaw ntawm cov tawv nqaij zoo li hydroquinone. Hydroquinone raug txwv nyob rau hauv ntau lub teb chaws vim nws cytotoxicity thiab txo qis tyrosinase kev ua. Ntau cov kev tshawb fawb tshawb fawb qhia tias arbutin yog ob qho tib si zoo thiab tsis zoo rau qhov tshwm sim ntawm mob qog noj ntshav. Hauv ib txoj kev tshawb fawb, nws tau pom tias arbutin txo qhov kev pheej hmoo ntawm mob qog noj ntshav, thaum lwm txoj kev tshawb fawb tau lees tias cov kab mob hauv plab tuaj yeem hloov arbutin rau hauv hydroquinone, muab qhov chaw zoo rau kev mob qog noj ntshav.
Alpha Arbutin yog dab tsi?
Alpha arbutin yog ib pawg ntawm arbutin muab los ntawm nplooj qhuav ntawm cov nroj tsuag xws li blueberry, cranberry, thiab bearberry, uas inhibits tyrosinase thiab yog li tiv thaiv kev tsim ntawm melanin. Thaum piv rau beta arbutin, alpha arbutin tiv taus cua sov ntau dua, muaj lub teeb ruaj khov dua, thiab muaj cov dej solubility siab.
Muaj ntau yam txiaj ntsig ntawm kev siv alpha arbutin. Alpha arbutin txo qhov chaw tsaus thiab pigmentation thiab pab ua kom pom kev ntawm daim tawv nqaij. Tsis tas li, nws muaj kev nyab xeeb dua li hydroquinone, maj mam rau ntawm daim tawv nqaij, thiab txhawb nqa txawm tias tawv nqaij. Ib tug neeg uas muaj txhua hom tawv nqaij tuaj yeem siv alpha arbutin los kho pigmentation thiab tan-txog kev txhawj xeeb. Tsuas yog qee qhov kev mob tshwm sim tshwm sim nrog kev siv alpha arbutin. Lawv yog cov tshav kub hnyiab thiab kev loj hlob ntawm pob txuv me me, sunburns, thiab kev tsis haum tshuaj. Qhov kev nyab xeeb ntawm alpha arbutin yuav tsum siv rau hauv cov khoom tu tawv nqaij yog txog li 2%.
Dab tsi zoo sib xws ntawm Arbutin thiab Alpha Arbutin?
- Arbutin thiab alpha arbutin yog glycosylated hydroquinones.
- Alpha Arbutin yog ib qho ntawm ob hom arbutin.
- Ob leeg yog muab los ntawm ntuj tsim.
- Lawv inhibit tyrosinase kev ua haujlwm.
- Yog li, lawv inhibit kev tsim ntawm melanin.
- Ob hom txo cov tawv nqaij pigmentation los ntawm UV hluav taws xob los ntawm lub hnub.
- Tsis tas li ntawd, arbutin thiab alpha arbutin ua raws li cov tawv nqaij ua kom pom kev.
Qhov txawv ntawm Arbutin thiab Alpha Arbutin yog dab tsi?
Arbutin yog glycosylated hydroquinone uas inhibits tyrosinase, tiv thaiv kev tsim ntawm melanin, thaum alpha-arbutin yog ib qho ntawm ob hom arbutin uas tiv taus tshav kub, qhia ntau lub teeb ruaj khov thiab dej solubility siab dua li lwm yam. daim ntawv. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm arbutin thiab alpha arbutin. Kev nyab xeeb concentration rau kev siv arbutin nyob rau hauv cov nqe lus ntawm alpha daim ntawv yog 2%, thiab beta daim ntawv yog 7%.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm arbutin thiab alpha arbutin hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Arbutin vs Alpha Arbutin
Arbutin yog ib hom glycosylated hydroquinone uas inhibits tyrosinase thiab yog li tiv thaiv kev tsim ntawm melanin. Alpha arbutin yog ib pawg ntawm arbutin. Lwm daim ntawv ntawm arbutin yog beta arbutin. Ob hom no txo cov tawv nqaij pigmentation los ntawm UV hluav taws xob ntawm lub hnub thiab ua raws li daim tawv nqaij lightening agents. Beta arbutin muaj cov dej solubility tsawg, tsis muaj cua sov tsis kam, thiab tsis muaj teeb pom kev zoo. Alpha arbutin muaj dej solubility siab, siab kub tsis kam, thiab siab lub teeb stability zog. Yog li, qhov no qhia txog qhov sib txawv ntawm arbutin thiab alpha arbutin.
