Koj Paub Ntau Txog Arbutin Npaum Li Cas?

Koj paub ntau npaum li cas txog arbutin?

Arbutin , tseem hu ua arbutin los yog myricetin, yog thawj zaug uas muab los ntawm cov nroj tsuag ntsuab. Nws yog ib phau ntawm "ntsuab", "muaj kev ruaj ntseg" thiab "muaj txiaj ntsig" Ib qho ntawm daim tawv nqaij ntxuav cov khoom ua kom nquag plias. Nws tuaj yeem nkag mus rau ntawm daim tawv nqaij, tsis muaj kev cuam tshuam cov proliferation ntawm daim tawv nqaij hlwb nyob rau tib lub sij hawm, ua tsis zoo rau cov tawv nqaij tyrosinase kev ua si, thaiv qhov tsim ntawm melanin, tyrosinase los ntawm lawv tus kheej kom ncav lub decomposition thiab excretion ntawm melanin, Yog li txo cov tawv nqaij pigmentation , tshem tawm cov pigmentation thiab quav hnav. Nws tsis tsim melanoma hlwb mob toxic, irritating, kev phiv tshuaj, thiab raws li emollients, ntau invasive, sterilization thiab synergistic anti-inflammatory effect. Yog tam sim no lub nrov tshaj plaws thiab muaj kev nyab xeeb thiab siv tau ib qho ntawm cov ntaub ntawv cov ntaub ntawv cov khoom noj khoom haus, tab sis tseem yog lub xyoo pua nees nkaum, feem ntau cov kev sib tw ntawm daim tawv nqaij ntxuav tes freckle activator. Arbutin muaj purity siab heev thiab zoo heev, yuav luag tsis muaj kev paub ntawm dihydrobenzene, yog li nyob deb ces tsuas yog ua tau raws li cov txheej txheem kev sib tw arbutin.

Kev faib tawm:

Arbutin yuav muab faib ua α-thiab β-hom, ob leeg tau muaj inhibition of tyrosining enzyme mus cuag cov nyhuv ntawm whitening.Li no, feem ntau ntawm arbutin rau kev ua lag luam yog β-arbutin, tsuas yog ob peb α-arbutin manufacturers.Thaum nws los ntawm tus nqi, α-arbutin yog 8 lub sij hawm tshaj β-arbutin , raws li, cov nyhuv dawb yog ntau tshaj 15 zaug lub β-arbutin . Qhov sib txawv ntawm qhov sib txawv hauv lub cev yog qhov kev hloov ua piv txwv: α-arbutin yog li 180 degrees, thaum β-arbutin yog-60 los yog li ntawd.
