I-Theaflavins (TFS)na-I-Thearubigins (TRS)Amaqembu amabili ahlukene ahlukene amakhompiyutha e-polyphenolic atholakala itiye elimnyama, ngalinye linezinto ezihlukile zamakhemikhali nezakhiwo. Ukuqonda umehluko phakathi kwalezi zinhlanganisela kubalulekile ukuze uqonde ukunikela ngamanye awo kwizici nezinzuzo zezempilo zetiye elimnyama. Lo mbhalo uhlose ukuhlinzeka ngokuhlola okuphelele kokungafani phakathi kweTheaflavins nama-Thearubigins, asekelwa ubufakazi obuvela ocwaningweni olufanele.
I-Theaflavins ne-TheArubigins ngama-flavonoids womabili anikela ngombala, ukunambitheka kanye nomzimba wetiye.I-Theaflavins i-orange noma ibomvu, futhi i-swearigicins ibomvu-nsundu. I-Theaflavins yi-flavonoid yokuqala yokuqhamuka ngesikhathi sokuxineka, ngenkathi kuvela ama-theARebigin kamuva. I-Theaflavins ineqhaza le-astringecy yetiye, ukukhanya nokukhanya, ngenkathi ama-thearigigins anikela ngamandla nangomlomo wawo.
I-Theaflavins iyisigaba sezinhlanganisela ze-polyphenolic ezibangela umbala, ukunambitheka, kanye nezindawo ezikhuthaza ngempilo yetiye elimnyama. Bakhelwe ngokuhlukahluka kwe-oxidative of Catechins ngesikhathi senqubo yokuvutshelwa kwamaqabunga etiye. Izintaba zaziwa ngemiphumela yazo ye-antioxidant kanye ne-anti-ukuvuvukala, ezixhumene nezinzuzo ezahlukahlukene zezempilo, kufaka phakathi ukuvikelwa kwenhliziyo, izakhiwo zokulwa nomdlavuza, kanye nemiphumela elwa nokuguga.
Ngokolunye uhlangothi,IzuluIzihlanganisi ezinkulu ze-polyphenolic ezithathwe futhi ezivela kwi-oxidation of itiye poelpenols ngesikhathi sokuvutshelwa kwamaqabunga etiye. Banesibopho sombala obomvu ocebile kanye nokunambitheka kwesimo setiye elimnyama. Ama-TheArubigins ahlotshaniswe ne-antioxidant, anti-inflammatory, kanye nezindawo ezivikela isikhumba, ezibenza babe yisihloko esidlangile emkhakheni wokulwa nokuguga nokuguga.
Amakhemikhali, eTheaflavins ahlukile kuma-thearubigins ngokuya ngesakhiwo sawo se-molecular kanye nokwakheka kwabo. I-Theaflavins iyizinhlanganisela ze-Dimric, okusho ukuthi inhlanganisela yamayunithi amabili amancane iyabakha, ngenkathi ama-theaRubigins amakhompiyutha akhudlwana avela kwi-polymerization yama-flavonoid ahlukahlukene ngesikhathi sokuvutshelwa kwetiye. Lokhu kuhlulwa kwesakhiwo kunomthelela emisebenzini yawo ehlukile yemvelo kanye nemiphumela yezempilo engaba khona.

I-Theaflavins yiqembu eliyinhloko lezinhlanganisela ezisetshenziselwa ukuhlola ikhwalithi yetiye elimnyama. Isilinganiso seTheaflavins to Theaarbigins (TF: tr) kufanele kube ngu-1: 10 kuya ku-1: 12 ngetiye elimnyama elimnyama. Isikhathi sokuvutshelwa yinto enkulu ekugcinweni kwe-TF: TR isilinganiso.
I-Theaflavins kanye nama-swearibigins yimikhiqizo yesimo esenziwe kusuka kuma-catechins ngesikhathi se-enzymatic oxidation of Tea ngesikhathi sokukhiqiza. I-Theaflavins inikeza umbala obomvu we-orange noma owolintshi ukuze ifake isandla emmoyeni womlomo kanye nobungako bokwakheka kwekhilimu. Zingamakhompiyutha e-Dimric anesikhumba se-benzotropolone esakhiwa kusuka ku-co-oxidation of ngazimbili ezikhethiwe zeCatechins. I-oxidation yendandatho ye-B (-) - I-Epigallocatechin noma (-) - I-Epigallocatechin Galletate ilandelwa ngokulahleka kwe-CO2 kanye ne-I-RIng ye-B (- -) - Epicatechin Gallate Molecule (Umdwebo 12.2). Kukhonjwe ama-reatleflavins amane etiye elimnyama: Theaflavin, iTheaflavin-3-Monogallate, Theaflavin-3'-Monogaltate, kanye neTheaflavin-3,3-DisAllate. Ngaphezu kwalokho, ama-steoosomers abo nama-derivatives angaba khona. Muva nje, ukuba khona kweTheaflavin Trigallate kanye ne-tetragallate etiyeni elimnyama kubikwa (chen et al., 2012). I-Theaflavins ingaqhubeka nokuqhutshwa. Kungenzeka futhi nabameleli bokwakhiwa kwe-polymeric swearubigins. Kodwa-ke, indlela yokuphendula ayikaziwa kuze kube manje. I-TheArubigins ingumbala obomvu onsundu noma omnyama onsundu etiyeni emnyama, okuqukethwe kwabo kufinyelela ku-60% wesisindo esomile sokufakwa kwetiye.
Mayelana nezinzuzo zezempilo, ama-Theaflavins afundwe kakhulu yindima yawo engaba khona ekuthuthukiseni impilo yenhliziyo. Ucwaningo luphakamise ukuthi ama-Theaflavins angasiza ukunciphisa amazinga e-cholesterol, athuthukise umsebenzi we-vessel, futhi asebenzise imiphumela yokulwa nokuvuvukala, konke okuzuzisa impilo yenhliziyo. Ngokwengeziwe, ama-Theaflavins akhombise amandla okuvimbela ukukhula kwamaseli omdlavuza futhi angaba nezakhiwo ezilwa nesifo sikashukela.
Ngakolunye uhlangothi, ama-thearubigins ahlotshaniswe nemiphumela ye-antioxidant kanye nokulwa nokuvuvukala, okubaluleke kakhulu ekulweni nokuxineka nokuvuvukala emzimbeni. Lezi zakhiwo zinganikela ekugugeni okungama-anti-anting kanye nemiphumela yokuvikela isikhumba yama-thearubigins, kubenza babe nesihloko esizithandayo eSkincare kanye nocwaningo oluhlobene nobudala.
Ekuphetheni, Theaflavins kanye nama-swearibigins ahlukene amakhompiyutha e-polyphenolic atholakala etiyeni elimnyama, ngalinye linezingoma zamakhemikhali eziyingqayizivele nezinzuzo ezingaba khona zezempilo. Ngenkathi iTheaflavins ixhunyaniswe nempilo yenhliziyo, izakhiwo ze-anti-Cancer, kanye nemiphumela engaba khona ye-anti-sikashukela, i-anti-inclusin ihlanganiswe ne-antioxidant, anti-camvuling, kanye nezakhiwo ezivikela isikhumba, ezibenza babe yisihloko esithi inzalo ekulweni nocwaningo lokuguga nokuguga.
