Nws yog ib zaug hu ua "whitening kub", thiab nws lub koob npe nrov nyob rau hauv nws incomparable whitening nyhuv ntawm ib sab, thiab qhov nyuaj thiab tsis txaus ntawm nws extraction ntawm lwm tus.Cov nroj tsuag Glycyrrhiza glabra yog lub hauv paus ntawm Glabridin, tab sis Glabridin tsuas yog tso nyiaj rau 0.1% -0.3% ntawm nws cov ntsiab lus tag nrho, uas yog hais tias, 1000kg ntawm Glycyrrhiza glabra tsuas tuaj yeem tau 100g ntawm.Glabridin, 1g ntawm Glabridin yog sib npaug rau 1g ntawm lub cev kub.
Hikarigandine yog ib tug neeg sawv cev ntawm cov khoom xyaw tshuaj ntsuab, thiab nws cov nyhuv whitening yog pom los ntawm Nyiv
Glycyrrhiza glabra yog cov nroj tsuag ntawm genus Glycyrrhiza.Tuam Tshoj yog lub teb chaws uas muaj cov tshuaj ntsuab nplua nuj nyob hauv lub ntiaj teb, thiab muaj ntau dua 500 hom tshuaj ntsuab siv hauv kev kho mob, cov uas siv ntau tshaj plaws yog licorice.Raws li kev txheeb cais, qhov kev siv ntawm licorice yog ntau dua 79%.
Vim muaj keeb kwm ntev ntawm daim ntawv thov, nrog rau lub koob npe nrov, qhov kev tshawb fawb ntawm tus nqi ntawm licorice tsis tau tsuas yog tawg los ntawm thaj chaw txwv, tab sis kuj tau nthuav dav daim ntawv thov.Raws li kev tshawb fawb, cov neeg siv khoom hauv Asia, tshwj xeeb tshaj yog nyob hauv Nyij Pooj, muaj kev hwm rau cov tshuaj pleev ib ce uas muaj cov khoom xyaw tshuaj ntsuab.114 cov khoom xyaw tshuaj ntsuab tshuaj pleev ib ce tau sau tseg hauv "Japan's General Cosmetics Raw Materials", thiab twb muaj 200 hom tshuaj pleev ib ce uas muaj cov khoom xyaw hauv Nyij Pooj.
Nws tau lees paub tias muaj cov nyhuv whitening super, tab sis dab tsi yog qhov nyuaj hauv kev siv tswv yim?
Lub hydrophobic ib feem ntawm licorice extract muaj ntau yam flavonoids.Raws li lub ntsiab lus tseem ceeb ntawm nws cov hydrophobic feem, halo-glycyrrhizidine muaj cov nyhuv inhibitory ntawm melanin ntau lawm thiab kuj muaj cov tshuaj tiv thaiv thiab tiv thaiv oxidant.
Qee cov ntaub ntawv sim qhia tias cov nyhuv whitening ntawm lub teeb Glabridin yog 232 npaug siab dua li cov vitamin C zoo tib yam, 16 npaug siab dua li ntawm hydroquinone, thiab 1,164 npaug siab dua li ntawm arbutin.Yuav ua li cas kom tau txais kev ua kom muaj zog ua kom dawb huv, lub teeb Glabridin muab peb txoj hauv kev sib txawv.
1. Inhibition ntawm tyrosinase kev ua
Lub ntsiab whitening mechanism ntawmGlabridinyog inhibit qhov synthesis ntawm melanin los ntawm kev sib tw inhibiting tyrosinase kev ua si, tshem tawm ib feem ntawm tyrosinase los ntawm catalytic nplhaib ntawm melanin synthesis thiab tiv thaiv kev khi ntawm substrate rau tyrosinase.
2. Antioxidant nyhuv
Nws tuaj yeem cuam tshuam ob qho kev ua haujlwm ntawm tyrosinase thiab dopa pigment interchange thiab kev ua haujlwm ntawm dihydroxyindole carboxylic acid oxidase.
Nws tau raug pom tias ntawm qhov concentration ntawm 0.1mg / ml, photoglycyrrhizidine tuaj yeem ua rau cytochrome P450 / NADOH oxidation system thiab tshem tawm 67% ntawm cov dawb radicals, uas muaj zog antioxidant.
3.Inhibit inflammatory yam thiab tiv thaiv UV
Tam sim no, kev tshawb fawb tsawg dua tau tshaj tawm txog kev siv photoglycyrrhizidine hauv kev tshawb fawb ntawm UV-induced tawv nqaij photoaging.Xyoo 2021, nyob rau hauv ib tsab xov xwm hauv phau ntawv xov xwm Journal of Microbiology thiab Biotechnology, photoglycyrrhizidine liposomes tau kawm txog lawv lub peev xwm los ameliorate UV light-induced erythema thiab kab mob ntawm daim tawv nqaij los ntawm inhibiting inflammatory yam.Photoglycyrrhizidine liposomes tuaj yeem siv los txhim kho bioavailability nrog tsawg cytotoxicity nrog rau zoo melanin inhibition, zoo txo cov kev qhia ntawm inflammatory cytokines, interleukin 6 thiab interleukin 10. Yog li, nws tuaj yeem siv los ua cov tshuaj pleev ib ce los tiv thaiv UV hluav taws xob ua rau cov tawv nqaij puas tsuaj. los ntawm inhibiting o, uas tej zaum yuav muab ib co tswv yim rau kev tshawb fawb ntawm tshav ntuj whitening tiv thaiv cov khoom.
Hauv cov ntsiab lus, cov nyhuv whitening ntawm photoglycyrrhizidine tau lees paub, tab sis nws tus kheej qhov xwm txheej yuav luag insoluble hauv dej, yog li nws yog qhov tshwj xeeb tshaj yog xav tau rau kev tsim thiab tsim cov txheej txheem hauv daim ntawv thov ntawm cov khoom tu tawv nqaij ntxiv, thiab tam sim no nws yog ib qho kev daws teeb meem zoo los ntawm liposome. tshuab encapsulation.Ntxiv mus, duabGlabridinliposomes tuaj yeem tiv thaiv UV-induced photoaging, tab sis qhov kev ua haujlwm no xav tau ntau qhov kev sim tshuaj xyuas kom paub tseeb thiab kev tshawb fawb daim ntawv thov yuav tsum tau ua.
Cov khoom tu tawv nqaij muaj photoGlabridin nyob rau hauv daim ntawv ntawm cov khoom xyaw compounding.
Txawm hais tias tsis muaj qhov tsis ntseeg tias photoGlabridine muaj cov nyhuv whitening zoo heev, nws cov nqi raw khoom tseem txwv tsis pub vim muaj teeb meem hauv kev rho tawm thiab cov ntsiab lus.Hauv kev kho kom zoo nkauj R & D, kev ua haujlwm ntawm kev tswj cov nqi yog ncaj qha txuas rau cov ntsiab lus thev naus laus zis thiab txheej txheem kev tshawb fawb.Yog li ntawd, nws yog ib txoj hauv kev zoo los tswj cov nqi ntawm cov formulations thiab ua kom muaj kev nyab xeeb thiab ua tau zoo los ntawm kev xaiv cov khoom xyaw nquag thiab sib xyaw ua ke hauv kev sib xyaw nrog photoglycyrrhizidine.Ntxiv rau qib R & D, kev tshawb nrhiav ntxiv yog xav tau txog kev tshawb fawb ntawm photoglycyrrhizidine liposomes thiab cov txheej txheem rho tawm tshiab.
