Siv
4-Hydroxycinnamic acid yog hydroxy derivative ntawm Cinnamic Acid nrog antioxidant zog. Nws yog ib qho tseem ceeb ntawm lignocellulose. Cov kev tshawb fawb qhia tias 4-Hydroxycinnamic acid tuaj yeem txo qhov kev pheej hmoo ntawm mob qog noj ntshav los ntawm kev txo qis kev tsim cov carcinogenic nitrosamines. Ib txoj kev tshawb fawb tsis ntev los no tau tshaj tawm tias 4-Hydroxycinnamic acid tuaj yeem ua cov tshuaj tua kab mob hauv cov muv los ntawm kev hloov pauv cov noob caj noob ces xav tau rau kev loj hlob ntawm zes qe menyuam. Cov tshuaj no muaj nyob rau hauv paj ntoos ib qho tseem ceeb ntawm cov neeg ua haujlwm muv noj, tab sis nws tsis pom nyob rau hauv huab tais bees'royal jelly.
Daim ntawv thov
p-Hydroxycinnamic acid, tseem hu ua p-coumaric acid, yog tau los ntawm kev ua ntawm p-hydroxybenzaldehyde thiab malonic acid. P-hydroxycinnamic acid tam sim no feem ntau yog siv rau hauv cov txuj lom los yog acidulant rau dej haus, thiab kuj yog ib qho antioxidant rau roj. Hauv kev lag luam kws tshuaj, nws yog cov khoom siv raw ntawm ntau cov tshuaj, xws li cov khoom siv tshuaj tiv thaiv adrenergic esmolol. Tsis tas li ntawd, p-hydroxycinnamic acid kuj yog siv los ua tus neeg sawv cev acidifying hauv cov tshuaj thiab ua tus neeg sawv cev hauv cov tshuaj, nrog rau cov tshuaj nruab nrab, xws li rau cov synthesis ntawm cov tshuaj expectorant tshiab Rhododendron; Nws yog siv rau kev tsim cov Kexinding, tshuaj kho mob plawv. Intermediates, thiab siv nyob rau hauv kev tsim cov tshuaj loog hauv zos, fungicides thiab hemostatic tshuaj; nws kuj muaj cov nyhuv inhibiting mob qog noj ntshav. Hauv kev ua liaj ua teb, nws yog siv los tsim cov nroj tsuag kev loj hlob, kev ua haujlwm ntev ntawm fungicides thiab preservatives rau txiv hmab txiv ntoo thiab zaub preservation. Hauv kev lag luam tshuaj, p-hydroxycinnamic acid yog ib qho tseem ceeb heev tsw thiab tsw, feem ntau yog siv los kho cov txuj lom xws li ntsim cherries, apricots, thiab zib mu. Nws yog siv nyob rau hauv kev npaj ntawm xab npum thiab cosmetic essence nyob rau hauv kev lag luam tshuaj txhua hnub. Hauv cov tshuaj pleev ib ce, p-hydroxycinnamic acid tuaj yeem tiv thaiv kev ua haujlwm ntawm tyrosinase monophenolase thiab diphenolase, ua rau 50% txo qis hauv monophenolase kev ua thiab diphenolase kev ua haujlwm, thiab siv hauv tshuaj pleev ib ce los tiv thaiv kev tsim melanin.
