Ukusebenza kunye neeNzuzo

I-tea polyphenols ine-antioxidant kunye ne-free radical scavenging effects, inciphisa kakhulu imixholo ye-serum ye-cholesterol epheleleyo, i-triglyceride kunye ne-low-density lipoprotein cholesterol kwi-hyperlipidemia, kunye nokubuyisela nokukhusela umsebenzi we-vascular endothelium.Impembelelo ye-hypolipidemic yeti ye-polyphenols sesinye sezizathu eziphambili zokuba kutheni iti inokwenza abantu abatyebe kakhulu banciphise umzimba ngaphandle kokuphindaphinda.

Umsebenzi woNonophelo lwezeMpilo

Iziphumo zeHypolipidemic:

I-tea polyphenols inokunciphisa kakhulu imixholo ye-serum epheleleyo ye-cholesterol, i-triglyceride kunye ne-low-density lipoprotein cholesterol kwi-hyperlipidemia, kwaye ibuyisele kwaye ikhusele umsebenzi we-vascular endothelium.Impembelelo ye-hypolipidemic yeti ye-polyphenols sesinye sezizathu eziphambili zokuba kutheni iti inokwenza abantu abatyebe kakhulu banciphise umzimba ngaphandle kokuphindaphinda.

Isiphumo se-Antioxidant:

I-polyphenols yeti inokuthintela inkqubo ye-lipid peroxidation kunye nokuphucula umsebenzi we-enzymes emzimbeni womntu, ukuze ibe nefuthe le-anti-mutation kunye ne-anti-cancer.

Impembelelo yeAntitumor:

I-polyphenols yeti inokuthintela ukuhlanganiswa kwe-DNA kwiiseli zethumba kwaye ibangele ukwaphuka kwe-DNA eguqukayo, ngoko inokuthintela isantya sokwenziwa kweeseli zethumba kwaye ithintele ngakumbi ukukhula kunye nokwanda kwamathumba.

Ukuvala inzala kunye nokukhutshwa kwetyhefu emzimbeni:

I-polyphenols yeti inokubulala i-botulinum kunye ne-spores kwaye inqande umsebenzi we-bacterial exotoxin.Ineempembelelo ze-antibacterial kwii-pathogens ezahlukeneyo ezibangela isifo sohudo, umgudu wokuphefumula kunye nosulelo lwesikhumba.I-polyphenols yeti ineempembelelo ezicacileyo zokuthintela kwi-Staphylococcus aureus kunye ne-Bacillus mutans ebangela usulelo olunamandla, ukutshisa kunye nokwenzakala.

Ukukhusela utywala kunye nesibindi:

ukwenzakala kwesibindi esinxilisayo ikakhulu kukwenzakala kwasimahla okubangelwa yi-ethanol.I-polyphenols yeti, njenge-scavenger yamahhala, inokuthintela ukulimala kwesibindi esinxilisayo.

Ukuphelisa ubutyhefu:

ungcoliseko olumandla lokusingqongileyo luneziphumo ezicacileyo eziyityhefu kwimpilo yabantu.Iipolyphenols zeti zine-adsorption eyomeleleyo kwisinyithi esinzima kwaye zinokwenza iikhompleksi ezinesinyithi esinzima ukuvelisa imvula, enceda ekunciphiseni isiphumo esiyityhefu sesinyithi esinzima emzimbeni womntu.Ukongeza, i-polyphenols yeti inokuphucula ukusebenza kwesibindi kunye ne-diuresis, ngoko ke inefuthe elihle lokuchasa kwityhefu ye-alkaloid.

Ezinye izicelo

Njengesongezo esihle kakhulu sezithambiso kunye neekhemikhali zemihla ngemihla: ine-antibacterial enamandla kunye ne-enzyme inhibition.Ke ngoko, inokuthintela izifo zolusu, iziphumo ezichasene nolusu, isuse ibala lolusu, ithintele i-caries yamazinyo, i-plaque yamazinyo, i-periodontitis kunye ne-halitosis.

Ukhuseleko lweSitsalo seTea

1. Ngokwendlela yokuvavanya ukhuseleko lomntu kunye nokuphumelela kovavanyo lwemigangatho yococeko lwezimonyo (i-2007 Edition), uvavanyo lokhuseleko lwee-polyphenols zeeti ezikhutshwe kwiti zenziwe.Iziphumo zovavanyo zibonise ukuba izifundo azizange zibe nefuthe elibi lolusu, kwaye akukho namnye kwabangama-30 owabonisa ukuba une-positive.Kubonisa ukuba izimonyo ezongeziweyo ngeti ye-polyphenols azikho ukusabela okucaphukisayo kumzimba womntu, zikhuselekile kwaye zinokusetyenziswa njengezongezo zokuthambisa.
