Ferulic acidtau siv rau hauv kev lag luam tshuaj pleev ib ce thiab kev lag luam tshuaj rau qee xyoo. Ob peb xyoos dhau los, cov ntsiab lus ntawm ferulic acid tau ntxiv rau kev ua lag luam ib qho tom qab, thiab txawm tias cov npe loj muaj feem cuam tshuam ntxiv. Yog li dab tsi ntawm cov khoom siv raw yog ferulic acid thiab nws cuam tshuam li cas rau kev tu tawv nqaij?
Ferulic acid (FA) yog ib qho derivative ntawm cinnamic acid (cinnamic acid) nrog cov tshuaj npe ntawm 4-hydroxy-methoxycinnamic acid, uas yog qhov tseem ceeb ntawm cov nroj tsuag phenolic acid. Cov ferulic acid muab rho tawm los ntawm nplej bran, angelica, ferula, chuanxiong thiab horsetail yog tag nrho cov derivatives ntawm cinnamic acid. Tau kawg, ferulic acid tsis tshua muaj nyob hauv lub xeev dawb hauv cov nroj tsuag. Nws feem ntau tshwm sim hauv cov nroj tsuag ua ke nrog oligosaccharides, polyamines, lipids thiab polysaccharides. Namely, sodium ferulic acid thiab ferulic acid ester, ob derivatives yeej embody thiab tuav cov yam ntxwv lom ntawm ferulic acid.
Ferulic acid tau siv ntau dua los ua tshuaj ua ntej, thiab nws kuj tseem siv tau los ua antioxidant hauv kev lag luam khoom noj. Nrog rau kev tshawb fawb tob tob hauv kev lag luam tshuaj pleev ib ce, ferulic acid maj mam siv hauv kev lag luam tshuaj pleev ib ce. Nws yog tsuas yog raws li kev ua kom dawb thiab antioxidant zog ntawm ferulic acid.
Qhov hnyav molecular ntawm ferulic acid yog kwv yees li 194 Daltons, thiab nws cov molecule me me thiab cov dej solubility tsawg ua rau nws yooj yim rau ferulic acid nkag mus rau ntawm daim tawv nqaij kom ua rau nws txoj haujlwm lom. Feem ntau, tus nqi ntawm ferulic acid ntxiv hauv cov tshuaj pleev ib ce yog nruab nrab ntawm 0.1% thiab 1.0%. Hauv qee cov khoom lag luam nyob sab Europe thiab Asmeskas, nws tseem ntxiv rau 3%, thiab qhov kev sib xyaw ua ke tsis yog tsawg.
Vim yog tus nqi pH tsawg ntawm cinnamic acid, yog li ferulic acid. Nyob rau hauv cov nqe lus ntawm stability test, nyob rau hauv chav tsev kub 25 ℃, ferulic acid muaj zoo stability nyob rau hauv ib tug tsis muaj pH=2.62 ~ 5.10. Raws li ib puag ncig ua alkaline ntau, ferulic acid kuj degraded.
