Apple Polyphenol dab tsi los ntawm Appchem?

Hauv kev noj qab haus huv niaj hnub no -} Nco ntsoov ntiaj teb, cog polyphenols tau txais kev saib xyuas ntau dua li cov antioxidants. Ntawm lawv,Kua polyphenolsTau dhau los ua cov kev tshawb fawb qhib hauv cov zaub mov, cov khoom noj qab haus huv, thiab cov tshuaj pleev ib ce kev lag luam vim lawv cov kev ua haujlwm ntawm kev nplua nuj thiab kev thov dav dav.

Kua polyphenols yog ib lo lus dav dav rau chav kawm ntawm polyphenolic tebchaw muab rho tawm cov txiv av tshiab, feem ntau pom hauv daim tawv nqaij ntawm cov txiv av uas tsis paub qab._[1] Nws zoo nkaus li brownish - cov hmoov liab nrog cov solubility zoo thiab yog cov solve tau yooj yim xws li dej, ethanol, thiab methanol.

Piv nrog lwm polyphenols tshuaj nyob rau hauv cov txiv hmab txiv ntoo, qhov loj tshaj plaws ntawm Kua polyphenols yog cov ntsiab lus ntau tshaj plaws ntawm Anthocyanin OLIGNOMERS OLIGNERS. Kev tshawb fawb tau pom tias cov ntsiab lus ntawm anthocyanins hauv cov txiv av tuaj yeem ncav cuag ntau dua 80% ntawm tag nrho cov ntsiab lus polyphenols nrog antioxidant zoo thiab bioavailability._[2]

1. Anthocyanins
Proantocyanins yog cov ntau ntau ntau feem hauv Apple polyphenols, nrog Anystanyanin B2 yog qhov tseem ceeb tshaj plaws. Cov tshuaj no yog oligomers tsim los ntawm tus polymerization ntawm catechins thiab epicatecins, feem ntau muaj 2 txog 5 monomers.

Cov ntaub ntawv tshawb fawb qhia tau tias:

• Cov ntsiab lus ntawm anthocyanins hauv cov txiv apple tsis tuaj yeem ncav cuag ntau dua 10 zaug uas paub tab yog cov txiv av paub tab
• Anthocyanin B2 Accounts rau 30-40% ntawm tag nrho cov duab polyphenol hauv cov txiv av
• Lub antioxidant muaj peev xwm ntawm Dimer Antocyanins yog 20 zaug ntawm cov vitamin C thiab 50 zaug uas ntawm cov vitamin E

2. Flavonoids
Nws tsuas yog suav nrog cov khoom sib xyaw xws li kev sib xyaw ua ke yog glycoside thiab hauv paus tawv ntoo glycoside. Cov tawv ntoo glycoside yog flavonoid compound txawv rau txiv apples, nrog cov haujlwm sib txawv ntawm lub cev.

Kev tshawb fawb qhia tau tias:

• Cov tawv ntoo glycoside muaj peev xwm ua tau zoo dua hypoglycemic los ntawm inhibiting sgrt2 transporter protein_[3]
• Quercetin glycoside muaj zog anti {{

3. Hydroxycinnamic acid
Chlorogenic acid yog ib qho tseem ceeb phebolic acid compound hauv cov txiv av. Chlorogenic acid tsis tsuas yog muaj zog antioxidant thaj chaw tab sis kuj tau ua pov thawj los tswj cov piam thaj hauv ntshav thiab cov nqaij ntshav ntshav.

Cov ntaub ntawv txhawb nqa:

• Chlorogenic acid account rau 10-15% ntawm tag nrho cov polyphenols hauv txiv apples
• Kev tshawb fawb qhia tau hais tias Chlorogenic acid tuaj yeem txhim kho kev ua kom muaj kev kub ntxhov. Nws cov kev ua antioxidant yog qhov zoo dua rau cov txiv ntoo uas feem ntau ntawm cov txiv ntoo phenolic acids

4. Dihydrochalcones
Phhloretin thiab nws daim ntawv glycoside yog qhov tshwj xeeb dihydrochalcone tebchaw pom hauv txiv apples. Nws cov tshuaj ntxuav hniav dawb tshwj xeeb thiab anti {{{- glycation cov khoom ua rau cov tshuaj no uas muaj kev nyiam ua kev lag luam tshuaj pleev ib ce.

Kev sim ua pov thawj:

• Phaloretin inhibits tyrosinase kev ua si_[4], muaj ib tug zoo heev anti - Cov nyhuv, thiab tuaj yeem tiv thaiv kev tsim cov hnub nyoog. Nws tuaj yeem tswj kev ruaj khov nyob rau hauv UV irradiation.

1. Zoo antioxidant thaj chaw

Kua polyphenols ua tau zoo antioxidant muaj peev xwm thiab muaj cov txiaj ntsig zoo dua rau cov txiv ntoo, thiab dpph thiab ntau tshaj li cov txiv hmab txiv ntoo thiab zaub. Qhov no muaj zog antioxidant muaj peev xwm ua rau nws tshem tawm dawb radicals thiab tiv thaiv hlwb los ntawm oxidative kev puas tsuaj.

2. Zoo ruaj khov
Piv nrog lwm polyphenols tshuaj, kua polyphenols pom zoo dua ruaj khov nyob rau hauv acidic thiab cua sov. Kev tshawb fawb tau qhia tias Apple Polyphenol Oxides Undergo Ntxiv cov kev tawm tsam ntawm qhov kub. Raws li lub sijhawm dhau mus, nws cov peev txheej antioxidant (frap tus nqi) nce, muab cov txiaj ntsig zoo rau nws cov ntawv thov hauv kev ua zaub mov noj._[5]

3. Siab Bioavailability
Vim yog cov ntsiab lus siab ntawm oligomeric anthocyanins hauv Apple Polyavails, lawv cov bioavailabs, lawv cov bioavailabs yog ua rau lwm yam siab molecular hnyav polyphenols. Cov chaw sim khomob tau pom tias antioxidant kev ua hauv cov ntshav mus txog nws lub ncov 2 teev tom qab siv Apple polyphenols.

1. Kev lag luam khoom noj khoom haus
Ua ib qho tshuaj tiv thaiv ntuj, kua polyphenols tau siv cov nqaij, cov khoom noj, uas muaj peev xwm txuas tau zoo ntev lub neej thiab tiv thaiv oxidation thiab lwj. Nyiv pom zoo kev siv Apple polyphenols ua zaub mov ntxiv thaum ntxov li 2000.

2. Kev Lag Luam Khoom Noj Khoom Haus

Lub xyoob ntoo muaj txiaj ntsig ntawm Kua Polyphenols yog qhov siab dua li ntawm lwm cov molecular hnyav polyphenols, vim lawv cov ntsiab lus siab oligomeric antocyanin cov ntsiab lus.

3. Daim ntawv thov ntawm cov tshuaj pleev ib ce
Qhov zoo tshaj whitening thiab anti {- kev kub siab ntawm cov hauv paus tawv ntoo extract thiab anthocyanins ua rau lawv tseem ceeb rau high-} cov tshuaj pleev ib ce. Kev sim ua tau pom tau hais tias ib qho kev ua kom huv si muaj 0.5% kua polyphenols tuaj yeem txhim kho cov tawv nqaij ci thiab elasticity tom qab 4 lub lis piam ntawm kev siv.

Nrog kev nce qib ntawm science thiab thev naus laus zis thiab kev siv lub kua loj ntxiv rau yav tom ntej, ua rau muaj kev pab rau tib neeg kev noj qab haus huv thiab kev txhim kho kom zoo.
