Glabridin originates los ntawm cov nroj tsuag Glycyrrhiza glabra, tsuas yog muaj nyob rau hauv lub hauv paus thiab qia ntawm Glycyrrhiza glabra (Eurasia), thiab yog lub ntsiab Isoflavone tivthaiv ntawm Glycyrrhiza glabra.Glabridinmuaj cov tshuaj dawb, tshuaj tiv thaiv kab mob, tshuaj tiv thaiv kab mob thiab lwm yam teebmeem.Vim cov ntsiab lus tsis tshua muaj ntawm glabridin thiab cov txheej txheem purification nyuaj, nws muaj lub npe ntawm "whitening kub".
1, Lub hauv paus ntsiab lus whitening ntawm Glabridin
Ua ntej nkag siab txog lub hauv paus ntsiab lus whitening ntawm glabridin, peb yuav tsum xub to taub luv luv txog qhov ua rau ntawm melanin ntau lawm.
Lub synthesis ntawm melanin yuav tsum muaj peb yam tseem ceeb:
Tyrosine: Cov khoom siv tseem ceeb rau kev tsim melanin.
Tyrosinase: tus nqi tseem ceeb txwv cov enzyme uas hloov tyrosine rau hauv melanin.
Reactive oxygen hom: Tyrosine yuav tsum tau ua ke nrog cov pa oxygen hauv cov txheej txheem tsim melanin raws li kev ua ntawm Tyrosinase.
Tyrosinase tuaj yeem tsim melanin tsis tu ncua.Sab nraud stimuli (nrog rau cov kab mob ultraviolet rays, o, ua xua, thiab lwm yam) tuaj yeem ua rau ntau qhov zais cia, ua rau blackening.
Nyob rau tib lub sijhawm, cov pa oxygen reactive (ROS) tshwm sim los ntawm ultraviolet hluav taws xob tuaj yeem ua rau cov phospholipid daim nyias nyias ntawm daim tawv nqaij, tshwm sim raws li erythema thiab pigmentation ntawm daim tawv nqaij. Yog li ntawd, ROS yog ib yam khoom uas tuaj yeem ua rau pigmentation ntawm daim tawv nqaij. Yog li ntawd, inhibiting nws tiam tuaj yeem inhibit qhov tsim ntawm melanin thiab pigmentation.
2 、 Qhov zoo tshaj plaws whitening ntawm Glabridin
Nyob rau hauv luv luv, cov txheej txheem ntawm whitening thiab pom lightening yog txheej txheem ntawm kev sib ntaus sib tua tiv thaiv Tyrosinase thiab reactive oxygen hom.
Glabridin feem ntau inhibits cov kev ua ntawm Tyrosinase los ntawm kev sib tw kev sib deev inhibition, noj ib feem ntawm Tyrosinase deb ntawm lub catalytic nplhaib ntawm melanin synthesis, tiv thaiv kev sib xyaw ntawm substrate thiab Tyrosinase, yog li inhibiting lub synthesis ntawm melanin.glabridinnws tus kheej muaj zoo antioxidant thiab anti-inflammatory teebmeem.
Los xaus,glabridinFeem ntau inhibits melanogenesis los ntawm peb cov lus qhia: inhibiting kev ua ntawm Tyrosinase, inhibiting tiam ntawm reactive oxygen hom, thiab inhibiting o.
Kev sim tau pom tias nws yog ib qho ceev, ua tau zoo, thiab ntsuab whitening thiab freckle tshem tawm cov tshuaj pleev ib ce ntxiv.Muaj cov ntaub ntawv sim qhia tias cov nyhuv whitening ntawm Glabridin yog 232 npaug ntawm cov vitamin C, 16 npaug siab dua hydroquinone (quinone), thiab 1164 npaug ntawm "arbutin".
Kev piav qhia: Lub peev xwm ua tau zoo thiab cov ntawv thov tau hais hauv kab lus no yog tag nrho los ntawm cov ntaub ntawv muaj nyob rau pej xeem.
