Qhov sib txawv ntawm α-arbutin thiab β-arbutin

α-arbutinthiab β-arbutin yog ob qho tib si tshuaj lom neeg sib txuas uas feem ntau siv hauv cov khoom siv tawv nqaij rau lawv cov tawv nqaij-lightening thiab brightening teebmeem.Thaum lawv sib koom cov qauv tseem ceeb zoo sib xws thiab cov txheej txheem ntawm kev ua, muaj qhov sib txawv me me ntawm ob qho uas tuaj yeem cuam tshuam lawv cov txiaj ntsig thiab cov kev mob tshwm sim.

Raws li txoj cai, ob qho tib si α-arbutin thiab β-arbutin yog glycosides ntawm hydroquinone, uas txhais tau hais tias lawv muaj cov piam thaj molecule txuas nrog hydroquinone molecule.Cov txheej txheem zoo sib xws no tso cai rau ob lub tebchaw los cuam tshuam cov enzyme tyrosinase, uas koom nrog hauv kev tsim melanin.Los ntawm inhibiting tyrosinase, cov tebchaw no tuaj yeem pab txo qis melanin ntau lawm, ua rau cov tawv nqaij sib dua thiab ntau dua.

Thawj qhov sib txawv ntawm α-arbutin thiab β-arbutin nyob rau hauv txoj hauj lwm ntawm glycosidic daim ntawv cog lus ntawm cov piam thaj thiab hydroquinone moieties:

α-arbutin: Hauv α-arbutin, daim ntawv cog lus glycosidic txuas ntawm alpha txoj haujlwm ntawm lub nplhaib hydroquinone.Qhov kev tso npe no ntseeg tau los txhim kho kev ruaj ntseg thiab solubility ntawm α-arbutin, ua kom zoo dua rau daim tawv nqaij daim ntawv thov.Cov glycosidic daim ntawv cog lus kuj txo cov peev xwm rau oxidation ntawm hydroquinone, uas tuaj yeem ua rau tsim cov tshuaj tsaus nti uas tawm tsam qhov xav tau ntawm daim tawv nqaij-lightening nyhuv.

β-arbutin: Hauv β-arbutin, glycosidic daim ntawv cog lus txuas rau ntawm beta txoj hauj lwm ntawm lub nplhaib hydroquinone.Thaum β-arbutin tseem muaj txiaj ntsig zoo hauv inhibiting tyrosinase, nws yuav tsis ruaj khov dua li α-arbutin thiab nquag oxidation.Qhov oxidation no tuaj yeem ua rau tsim cov xim av sib xyaw uas tsis xav tau rau cov tawv nqaij lightening.

Vim nws qhov ruaj khov thiab solubility ntau dua, α-arbutin feem ntau suav hais tias yog daim ntawv zoo dua thiab nyiam rau daim ntawv thov kev tu tawv nqaij.Nws ntseeg tau tias yuav xa cov txiaj ntsig zoo ntawm daim tawv nqaij-lightening thiab tsis tshua muaj peev xwm ua rau tsis muaj xim lossis tsis xav tau kev phiv.

Thaum xav txog cov khoom tu tawv nqaij uas muajarbutin, Nws yog ib qho tseem ceeb uas yuav tsum tau nyeem cov khoom muaj npe los txiav txim seb puas siv α-arbutin lossis β-arbutin.Thaum ob lub tebchaw tuaj yeem ua haujlwm tau zoo, α-arbutin feem ntau suav tias yog qhov kev xaiv zoo tshaj vim nws txoj kev ruaj khov thiab muaj zog.

Nws tseem ceeb heev uas yuav tsum nco ntsoov tias cov tawv nqaij rhiab heev tuaj yeem sib txawv.Qee tus neeg yuav muaj kev phiv xws li tawv nqaij khaus lossis liab thaum siv cov khoom uas muaj arbutin.Raws li nrog rau txhua yam khoom siv tawv nqaij, nws raug pom zoo kom ua ib qho kev kuaj ua ntej siv cov khoom siv rau thaj tsam loj ntawm daim tawv nqaij thiab sab laj nrog kws kho mob dermatologist yog tias koj muaj kev txhawj xeeb txog qhov muaj peev xwm tshwm sim.

Hauv kev xaus, ob qho tib si α-arbutin thiab β-arbutin yog glycosides ntawm hydroquinone siv rau lawv cov teebmeem ntawm daim tawv nqaij.Txawm li cas los xij, α-arbutin qhov chaw ntawm glycosidic daim ntawv cog lus ntawm alpha txoj hauj lwm muab kev ruaj ntseg thiab solubility ntau dua, ua rau nws qhov kev xaiv ntau dua rau cov khoom tu tawv nqaij txhawm rau txo qis hyperpigmentation thiab ua tiav cov tawv nqaij ntau dua.
