01 Anti-Melanin
Nws tau tshaj tawm tiasferulic acidtuaj yeem inhibit lossis txo cov kev ua haujlwm ntawm melanocytes. Kev siv 0.1-0.5% ferulic acid daws tuaj yeem txo cov melanocytes ntawm 117 ± 23 / mm2 txog 39 ± 7 / mm2; Nyob rau tib lub sijhawm, Ah Fuulic acid tuaj yeem cuam tshuam cov haujlwm ntawm tyrosinase. Ib qho tshuaj ferulic acid nrog qhov siab ntawm 5mmol / L tuaj yeem cuam tshuam cov haujlwm ntawm tyrosinase siab li 86%. Txawm hais tias qhov concentration ntawm cov tshuaj ferulic acid tsuas yog 0.5 mmol / L, nws qhov inhibition ntawm tyrosinase kev ua haujlwm tuaj yeem ncav cuag li 35%.
02 Antioxidant
Cov kev tshawb fawb tau pom tias ferulic acid yog nyob rau hauv cov antioxidant, nws muaj peev xwm txhawb lub cev los tsim glutathione thiab nicotinamide adenine dinucleotide phosphate (NADP), yog li rhuav tshem dawb radicals thiab txo UV puas rau ntawm daim tawv nqaij. Lub hauv paus ntsiab lus yog tej zaum cov kab hluav taws xob ultraviolet yuav tsim ntau yam hluav taws xob uas nqa cov dawb radicals ntawm peb cov tawv nqaij, thiab NADP tuaj yeem ua haujlwm nrog lwm cov khoom xyaw kom tshem tawm cov dawb radicals uas khiav ncig.
03 tiv thaiv tshav ntuj
Kuj tseem muaj cov ntaub ntawv qhia tias ferulic acid tuaj yeem nqus tau cov teeb ci ultraviolet hauv lub wavelength ntawm 290-330nm, tiv thaiv lossis txo qhov kev puas tsuaj ntawm lub teeb ntawm ultraviolet lub teeb rau ntawm daim tawv nqaij, thiab muaj peev xwm tiv thaiv hnub ci.
