Definition
Ntsuab Tshuaj yej Polyphenols (GTP) yog qhov sib txuas ntawm polyhydroxy phenolic tebchaw hauv tshuaj yej. Nws yog tsim ntawm ntau dua 30 cov tshuaj phenolic. Nws lub ntsiab lus tseem ceeb yog catechins thiab lawv cov lus qhia, uas tseem yog cov khoom xyaw nquag siv hauv kev kho mob. Cov tshuaj yej polyphenols muaj ntau lub cev kev ua haujlwm xws li kev tiv thaiv kev tiv thaiv, tiv thaiv hluav taws xob, tiv thaiv kev laus, txo cov roj ntshav, txo cov ntshav qab zib, inhibiting cov kab mob thiab enzymes, thiab lwm yam.
Muaj pes tsawg leeg
Cov tshuaj yej polyphenols yog qhov tseem ceeb uas txiav txim xyuas cov xim, aroma, saj thiab cov txiaj ntsig ntawm cov tshuaj yej, xam rau 20% mus rau 30% ntawm lub cev qhuav ntawm tshuaj yej. Raws li cov qauv thechemical, cov tshuaj yej polyphenols tau muab faib ua plaub pawg: catechins, flavonoids, anthocyanins, thiab phenolic acids. Ntawm lawv, catechins muaj cov ntsiab lus siab tshaj plaws, uas suav txog 60% mus rau 80% ntawm cov tshuaj yej polyphenols. Cov catechins yog feem ntau epicatechin (EC), epicatechin gallate (ECG), epigallocatechin (EGC) thiab epigallocatechin gallate (EGCG). Cov ntsiab lus siab tshaj plaws ntawm catechins hauv tshuaj yej yog EGCG, tom qab ntawd ECG, thiab ntxiv EGC.

Kev siv lub cev thiab tshuaj
Xim | Cov tshuaj yej polyphenols yog dawb amorphous crystalline tshuaj thaum nws hloov lub teeb daj rau xim av vim yog ob peb GTP oxidativein extraction. |
Ntxhi& saj | Lub teeb tshuaj yej frangrance thiab astringent saj |
Solublity | yooj yim soluble hauv ethanol, methanol, thiab ethyl acetate, acetone, thiab lwm yam, soluble me ntsis hauv roj, insoluble hauv cov kuab tshuaj organic xws li benzene thiab chloroform |
PH | ruaj khov ntawm pH 2-7, yooj yim rau oxidize thiab polymerize hauv qab teeb lossis pH> 8. |
Lwm yam | zoo kub tsis kam, hygroscopicity, tuaj yeem tsim cov ntsuab thiab dub sib txuas nrog hlau ions |
Muaj nuj nqi:
Raws li cov tshuaj ntxiv rau ntxiv thiab niaj hnub xav tau, tshuaj yej polyphenols muaj cov teebmeem tseem ceeb: muaj zog tiv thaiv kab mob (nrog rau cov kab mob ntawm daim tawv nqaij thiab lub qhov ncauj) thiab inhibition of oxidase (xws li tyrosinase, piam thaj hloov ntawm Streptococcus mutans) Enzymes, urinine decarboxylase, lipoxygenase, thiab lwm yam. ).
Tib lub sijhawm, nws tuaj yeem tiv thaiv lub hnub' s los ntawm kev ua kom tawv nqaij puas tsuaj. Tsis tas li ntawd, nws tseem tuaj yeem tshem tawm cov neeg ua pa tsw phem. Yog li, tshuaj yej polyphenols tuaj yeem siv rau hauv cov tshuaj pleev ib ce thiab cov khoom siv niaj hnub ua tshuaj tua kab mob tiv thaiv kab mob, tshuaj tiv thaiv kab mob, cov tshuaj tiv thaiv tawv ncauj, cov tawv nqaij ntxuav hniav dawb, cov tshuaj tiv thaiv hluav taws xob, cov tshuaj tiv thaiv tshav ntuj thiab tshuaj pleev ib ce tshwj xeeb, thiab lwm yam, zoo li hauv cov tshuaj pleev ib ce txhua hnub, xws li da dej Cov. Xab npum, tshuaj pleev ntsej muag, tshuaj zawv plaub hau, tshuaj ntxuav tes, tshuaj txhuam hniav, tshuaj txhuam hniav, tshuaj ntxuav hniav, tshuaj pleev qhov ncauj, los tiv thaiv lwm yam, thiab lwm yam.
2. Tswj cov ntshav liab
Cov tshuaj yej polyphenols tuaj yeem nkag siab ntau dua cov ntshav lipids, tshwj xeeb yog qis qis cov ntshav TG (triglycerides), TC (tag nrho cov roj cholesterol) thiab cov roj lipoprotein tsawg cov roj (LDL-C) cov ntsiab lus, thiab nce lipoprotein ntau dua. Tsis tas li, tshuaj yej polyphenols yog cov muaj zog inhibitors ntawm lipoprotein tsawg-oxidation, uas tuaj yeem tiv thaiv qhov kev hloov kho ntawm LDL, thiab muaj qee yam kev cuam tshuam.
