(-) -Epigallocatechin Gallate Hydrate (EGCG Hydrate) (CAS: 989-51-5), i-extract tea eluhlaza, i-polyphenol catechin enamandla i-antioxidant efumaneka kwi-tea eluhlaza, i-polyphenolic flavonoid enamandla efumaneka njengenxalenye yetiyi.Ibonisa i-antioxidant, i-antimutagenic, i-antitumor kunye ne-anti-inflammatory properties, ngaloo ndlela inegalelo kwizenzo zezempilo-eziluncedo.Ifumana ukusetyenziswa okunokubakho njengomgqatswa weziyobisi kwimiba yezoxubo, izithambiso, kunye nesondlo.
(-) -I-Epigallocatechin Gallate, i-catechin enkulu ye-59% ye-catechin iyonke kwi-tea eluhlaza, i-antioxidant enamandla kunye ne-antiangiogenic kunye ne-antitumor agent.I-EGCG ifundwe ngendima yayo kwi-chemoprevention yoluhlu lwasendle lwee-cancer, kubandakanya isibindi, isisu, ulusu, imiphunga, i-mammary gland kunye ne-colon cancers.Iziphumo zophononongo zibonisa ukuba i-egcg iyakwazi ukukhuthaza i-apoptosis, ikhuthaze ukukhula kweseli ukubanjwa kunye ne-block carcinogenesis ngokuchaphazela iindlela zokuhambisa umqondiso.
Umsebenzi:
1) I-EGCG inokunciphisa uxinzelelo lwegazi, iswekile yegazi, i-lipids yegazi.
2) I-EGCG inomsebenzi wokukhupha ama-radicals kunye nokuguga.
I-3) I-EGCG inokwandisa umsebenzi wokuzivikela kunye nokuthintela ukubanda.
I-4) I-EGCG inomsebenzi we-anti-radiation, i-anti-cancer, inqanda ukwanda kweseli yomhlaza.Ngomsebenzi oqinileyo wokuchasana ne-xxidation, inokuphelisa i-radical yasimahla yomzimba kwaye ixhathise ukuguquka kwethumba, ukuguga, ukudumba, intsholongwane njl.njl.
5) I-EGCG isetyenziselwa ukuchasana nebhaktheriya, kunye nomsebenzi wokwenza inzalo kunye ne-deodorization.
6) Ukuphucula imetabolism kunye ne-fat oxidation.
7) I-EGCG isetyenziswa kakhulu kwintsimi yokutya, amayeza kunye nokusetyenziswa kwansuku zonke kweemveliso zemichiza.
8) I-EGCG inokuthintela kunye nokunyanga ithumba elibi, i-hyperlipemia, i-arteriosclerosis, i-cerebral thrombosis, isifo seswekile i-obisity njl.
Isicelo:
I-1) Isetyenziswe kwintsimi yokutya, i-EGCG isetyenziswe njenge-antioxidant yendalo, i-antistaling agent, kunye ne-anti-fading agents.Yongeza i-polyphenols yeti ekudleni kunokugcina incasa yasekuqaleni, ukuthintela urhwaphilizo kunye nokuguqulwa kombala, kunye nomsebenzi wokuthintela kunye nokubulala ibhaktheriya, eya kuphucula imigangatho yokucoceka kokutya.
I-2) Isetyenziswe kwintsimi yamachiza, isetyenziselwa ukunyanga isifo senhliziyo, isifo seswekile kunye nomhlaza.
I-3) Isetyenziswe kwintsimi yezimonyo, i-EGCG iphethe umphumo wokulwa nemibimbi kunye nokuguga.Ukukhusela ulusu kwilanga eliyingozi, eliya kuthintela umhlaza wolusu.
Iindlela zokutsalwa kwee-polyphenols zeeti ezisuka kwiti ikakhulu ziquka indlela yokwahlula imvula, indlela yokwahlula i-adsorption, indlela ye-organic solvent extraction, indlela yokukhupha i-enzyme yokucoca ubushushu obuphantsi, indlela yokukhupha ityuwa, iindlela ezintsha eziphuhlisiwe ziquka i-supercritical solvent extraction.Apha sazisa eyona ndlela ixhaphakileyo yokwahlula ityuwa ye-calcium yetyuwa.Emva kokutyumza, amaqabunga eti afakwe emanzini ashushu kwi-80 ℃ ye-30min kwi-kettle yokukhutshwa, ihluziwe, ikhekhe lokucoca lihlanjwe ngamanzi amancinci abilayo, isisombululo sokuhlamba sidibaniswe ne-filtrate, kunye nezinye izinto ezifana ne i-caffeine inokutsalwa emva kokuba ikhekhe lokucoca lomile.I-filtrate igalelwe kwisitya se-precipitation, kwaye i-lime yamanzi e-saturated, i-lime yamanzi e-saturated kunye namanzi ahluthayo anetyuwa ayongezwa kumlinganiselo omalunga ne-1: 6: 5 ye-filtrate: amanzi e-lime: amanzi etyuwa.Emva kokuvuselela ngokupheleleyo, umxube uvumelekile ukuba ume i-30 min, i-filtration.Ikeyiki yokuhluza yafakwa kwisithambiso esisidiza kunye ne-0.5% ~ 0.8% ye-H2S04, ilungelelanise i-pH ye-7.1 ~ 7.2, kwaye emva koko usebenzise i-acetic acid okanye i-citric acid ukulungisa ixabiso le-pH ukuya ku-7.0, livuselelwe ngokupheleleyo, emva koko I-30min, ihluzo, uhlambe, i-filtrate yomiswa ngokutshiza ukufumana imveliso egqityiweyo.
