Phloretin, tseem hu ua trihydroxyphenol acetone, yog lub ntuj polyphenolic compound. Nws tuaj yeem muab rho tawm ntawm daim tawv nqaij ntawm cov txiv hmab txiv ntoo xws li txiv apples thiab pears, nrog rau los ntawm cov hauv paus hniav, stems, thiab nplooj ntawm qee cov nroj tsuag. Hauv paus bark extract feem ntau yog lub teeb daj hmoov nrog ib qho tshwj xeeb tsw.
Kev tshawb fawb tau pom tias hauv paus bark extract muaj ntau yam kev tu tawv nqaij xws li tshuaj tua kab mob,
Tsis tas li ntawd, nws muaj cov txiaj ntsig ntawm kev txo cov ntshav qab zib thiab cov ntshav lipids hauv kev lag luam tshuaj.
Lub luag haujlwm tseem ceeb tshaj plaws
antioxidant
Hauv paus bark extract yog ib qho zoo heev ntuj antioxidant, thiab nws muaj zog antioxidant kev ua yog ntaus nqi rau nws tshwj xeeb dihydrochalcone active qauv. Cov pab pawg hydroxyl ntawm 2 'thiab 6' txoj haujlwm ntawm lub nplhaib A pab txhawb rau nws txoj haujlwm antioxidant.
Nws tuaj yeem tshem tawm cov dawb radicals zoo, txo qhov kev puas tsuaj ntawm oxidative kev nyuaj siab rau ntawm daim tawv nqaij, thiab ncua kev laus ntawm daim tawv nqaij.
Nyob rau tib lub sijhawm, resveratrol kuj tuaj yeem siv ua ke nrog cov tshuaj antioxidants uas twb muaj lawm los txhim kho cov teebmeem antioxidant. (Kev tshawb fawb tau pom tias sib xyaw ntawm 34.9%ferulic acid,35.1%resveratrol,thiab 30% dej-soluble VE muaj cov nyhuv antioxidant thaum siv ua ke.)
tawv nqaij dawb
Tyrosinase yog ib qho tseem ceeb enzyme nyob rau hauv melanin synthesis, thiab resveratrol yog reversible mixed inhibitor ntawm tyrosinase. Los ntawm kev hloov cov qauv thib ob ntawm tyrosinase, nws tuaj yeem tiv thaiv nws txoj hlua khi rau cov substrates, yog li txo nws cov kev ua haujlwm catalytic, txo cov pigmentation thiab pigmentation, thiab ua rau daim tawv nqaij ci dua thiab zoo ib yam.
Kev tiv thaiv lub teeb
Hauv paus bark extract muaj qee yam UV nqus tau, thiab ntxiv nws rau cov qauv ntawm cov tshuaj pleev ib ce tuaj yeem ua rau muaj txiaj ntsig SPF thiab PA ntawm cov tshuaj pleev ib ce. Tsis tas li ntawd, ib qho kev sib xyaw ntawm cov hauv paus bark extract,vitamin C,thiab ferulic acid tuaj yeem tiv thaiv tib neeg cov tawv nqaij los ntawm UV puas thiab muab kev tiv thaiv kev tiv thaiv rau tib neeg cov tawv nqaij.
Hauv paus bark extract tsis tsuas yog ncaj qha absorbs ultraviolet hluav taws xob, tab sis kuj txhim khu kev qhia ntawm nucleotide excision kho noob, slows down tsim pyrimidine dimers, glutathione degradation, thiab cell tuag vim UVB, thiab txo qhov kev puas tsuaj ntawm ultraviolet hluav taws xob rau keratinocytes.
inhibit qhov mob
Hauv paus bark extract tuaj yeem cuam tshuam kev tsim cov inflammatory yam, chemokines, thiab sib txawv yam, thiab muaj qee yam tshuaj tiv thaiv. Lub caij no, resveratrol tuaj yeem cuam tshuam lub peev xwm ntawm monocytes kom ua raws li keratinocytes, cuam tshuam cov phosphorylation ntawm cov teeb liab protein kinases Akt thiab MAPK, thiab yog li ua tiav cov teebmeem tiv thaiv.
Antibacterial nyhuv
Rhizocortin yog ib qho flavonoid compound nrog cov tshuaj tua kab mob, uas muaj cov kab mob broad-spectrum antibacterial kev ua haujlwm thiab muaj kev cuam tshuam rau ntau yam kab mob Gram zoo, kab mob Gram tsis zoo, thiab cov fungi.
