Iimpawu zeMveliso:
1 Ukucoca iiradicals zasimahla
I-asidi ye-Ferulic ine-antioxidant enamandla, enokuphelisa i-oxygen free radicals, inhibit i-enzymes evelisa i-radicals yamahhala, ikhuthaza ukuveliswa kwee-enzymes eziphelisa ii-radicals zamahhala, ziphelise umonakalo we-oxidative kwi-membrane zeseli kunye ne-DNA ebangelwa yi-radicals yamahhala, kwaye ikhusele umzimba simahla umonakalo omkhulu.
2 Ukwenza mhlophe
I-Ferulic acid inokuthintela umsebenzi we-B16V kwi-melanocytes, kwaye ukusebenzisa i-0.1-0.5% isisombululo se-ferulic acid inokunciphisa inani le-melanocytes ukusuka kwi-117 ± 23 / mm2 ukuya ku-39 ± 7 / mm2; Ngaxeshanye, i-asidi ye-ferulic inokuthintela Umsebenzi we-tyrosinase.Isisombululo se-ferulic acid kunye ne-concentration ye-5mmol / L inokuthintela umsebenzi we-tyrosinase ukuya kwi-86%.Nokuba i-concentration ye-ferulic acid isisombululo yi-0.5mmol / L kuphela, izinga layo lokuthintela kumsebenzi we-tyrosinase linokufikelela malunga. 35%.
3 Ukumelana nomonakalo we-UV
Iasidi yeFerulic iqulethe isibini semibhobho edityanisiweyo ephindwe kabini, ethi ifunxe ngamandla imitha ye-UV ukusuka kwi-290 ukuya kwi-350nm. iasidi inceda ukunqanda umonakalo weseli obangelwa yimitha yeultraviolet, yongeza ukukwazi kolusu ukuxhathisa ukufota kunye nokuthintela umhlaza wolusu.
4 Anti ukudumba
I-asidi ye-Ferulic ine-anti-inflammatory kunye ne-wide-spectrum anti-allergic effects, kunye nesantya sokuthintela i-IL-4 kwi-concentration ye-4umol / L yi-18.2%.
5 Ukubakho kweBioavailability
I-asidi ye-Ferulic inefuthe elibalulekileyo lokufunxa kwe-transdermal ekhuthazayo, ngokungena kakuhle kwesikhumba kunye ne-bioavailability ephezulu.

Iingcebiso zokupheka
I-pH esebenzayo: 3.0-6.0.
I-asidi ye-Ferulic iyanyibilika emanzini ashushu, kodwa inokunqamka ngokulula emva kokupholisa; Kuyacetyiswa ukuba kwandiswe ukusetyenziswa kwe-polyols kwinkqubo kwaye ungeze i-cosolvent ethoxydiethylene glycol. i-pH ephezulu ngokugqithisileyo inokukhawulezisa ngokulula i-oxidation kunye nokuguquka kombala we-ferulic acid.

Ugcino
Gcina kwindawo epholileyo (<25℃), eyomileyo, nemnyama, itywinwe kwaye igcinwe. Kufuneka isetyenziswe ngokukhawuleza emva kokuvula itywina; Phantsi kweemeko ezicetyiswayo zokugcinwa, iimveliso ezingavulwanga zineshelufu yeenyanga ezingama-24.
