Ferulic acid, tshuaj lub npe uas yog 3-methoxy-4-neneneba hydroxycinnamic acid, yog ib qho ntawm cov khoom xyaw zoo ntawm cov tshuaj suav tshuaj no vim nws cov ntsiab lus siab hauv Ferula, Angelica, Chuanxiong, Cimicifuga, Semen Ziziphi spinosae, thiab lwm yam.Ferulic acidmuaj ntau yam kev ua ub no thiab tau siv dav hauv ntau yam tshuaj pleev ib ce. Cia peb saib lub luag haujlwm thiab kev ua tau zoo ntawm ferulic acid hauv cov tshuaj pleev ib ce hauv cov ntawv hauv qab no.
1 、 Lub luag haujlwm thiab kev ua tau zoo ntawmferulic acidhauv tshuaj pleev ib ce
1.Anti melanin
Qee cov ntawv tshaj tawm qhia tias ferulic acid tuaj yeem cuam tshuam lossis txo qis kev ua haujlwm ntawm melanocytes.Siv cov tshuaj 0.1 ~ 0.5% ferulic acid tuaj yeem txo tus naj npawb ntawm melanocytes ntawm 117 ± 23 / mm2 rau 39 ± 7 / mm2; Tib lub sijhawm, ferulic Cov kua qaub kuj tseem tuaj yeem cuam tshuam cov kev ua ntawm tyrosinase, nrog rau qhov concentration ntawm 5mmol / L ferulic acid tov uas nthuav tawm tus nqi inhibition txog li 86% ntawm tyrosinase kev ua haujlwm. ntawm tyrosinase kev ua haujlwm tuaj yeem ncav cuag li 35%.
2.Antioxidant
Kev tshawb fawb tau qhia tiasferulic acidkoom nrog hauv kev ua haujlwm antioxidant thiab tuaj yeem txhawb kev tsim cov glutathione thiab nicotinamide adenine dinucleotide phosphate (NADP) hauv lub cev, yog li tshem tawm cov dawb radicals thiab txo qhov kev puas tsuaj ntawm ultraviolet hluav taws xob rau ntawm daim tawv nqaij. radicals ntawm peb cov tawv nqaij, thiab NADP, nrog rau lwm cov khoom, tuaj yeem tshem tawm cov dawb radicals uas khiav mus ncig.
3. Cov tshuaj tiv thaiv tshav ntuj
Kuj tseem muaj cov ntaub ntawv qhia tias ferulic acid tuaj yeem nqus tau cov hluav taws xob ultraviolet hauv lub wavelength ntawm 290-330nm, tiv thaiv lossis txo cov tawv nqaij puas tsuaj los ntawm qhov wavelength ntawm ultraviolet hluav taws xob, thiab muaj peev xwm tiv thaiv lub hnub puas tsuaj.
2 、 Daim ntawv thov thiab pom zoo ntau npaum li cas ntawmferulic acid
1.Ferulic acidmuaj qhov sib txuas zoo heev.Thaum qhov concentration yog 7%, nws yog lub teeb pom kev zoo thiab siv dav hauv cov khoom siv tshuaj pleev thaiv hnub;
2.Ferulic acid tuaj yeem siv rau hauv lub ntsej muag cream, tshuaj pleev, qhov tseem ceeb, daim npog ntsej muag thiab lwm yam tshuaj pleev ib ce.
Specification: Ferulic acid 99%
Pom zoo noj ntau npaum: 0.1-1.0%
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.
