(-) -I-Epigallocatechin Gallate Hydrate (EGCG Hydrate) (i-CAS: 989-51-5), i-extract tea eluhlaza, i-polyphenol catechin antioxidant enamandla etholakala etiyeni eliluhlaza, i-polyphenolic flavonoid enamandla etholakala njengengxenye yetiye.Ibonisa izakhiwo ze-antioxidant, i-antimutagenic, i-antitumor kanye ne-anti-inflammatory, ngaleyo ndlela ibe nomthelela ezenzweni ezizuzisa impilo.Ithola ukusetshenziswa okungaba khona njengekhandidethi lomuthi emkhakheni wezokwelapha, izimonyo, nokondleka.
(-) -I-Epigallocatechin Gallate, i-catechin enkulu ebalwa ku-59% wengqikithi yamakatekhini etiyeni eliluhlaza, iyi-antioxidant enamandla kanye ne-antiangiogenic and antitumor agent.I-EGCG icutshungulwe ngeqhaza layo ekuvimbeleni i-chemoprevention yohla lwasendle lomdlavuza, okuhlanganisa isibindi, isisu, isikhumba, amaphaphu, indlala yebele kanye nomdlavuza wekoloni.imiphumela yocwaningo ibonisa ukuthi i-egcg iyakwazi ukuheha i-apoptosis, ikhuthaze ukuboshwa kokukhula kwamangqamuzana futhi ivimbele i-carcinogenesis ngokuthinta izindlela zokudlulisa isignali.
Umsebenzi:
1) I-EGCG inganciphisa umfutho wegazi, ushukela wegazi, i-lipids yegazi.
2) I-EGCG inomsebenzi wokukhipha ama-radicals kanye nokulwa nokuguga.
3) I-EGCG ingathuthukisa ukusebenza komzimba nokuvimbela imikhuhlane.
I-4) I-EGCG inomsebenzi wokulwa nemisebe, i-anti-cancer, ivimbela ukwanda kweseli lomdlavuza.Ngomsebenzi oqinile we-anti-xxidation, ingaqeda ama-radical mahhala omzimba futhi imelane nokuguqulwa kwesimila, ukuguga, ukuvuvukala, igciwane njll.
5) I-EGCG isetshenziselwa ukulwa namagciwane, nomsebenzi wokuvala inzalo nokuqeda iphunga.
6) Ukuthuthukisa imetabolism kanye ne-oxidation yamafutha.
7) I-EGCG isetshenziswa kabanzi emkhakheni wokudla, imithi kanye nemikhiqizo yamakhemikhali esetshenziswa nsuku zonke.
8) I-EGCG futhi ingavimbela futhi yelaphe isimila esiyingozi, i-hyperlipemia, i-arteriosclerosis, i-cerebral thrombosis, isifo sikashukela i-obisity njll.
Isicelo:
I-1) Isetshenziswa emkhakheni wokudla, i-EGCG isetshenziswa njenge-antioxidant yemvelo, i-antistaling agent, nama-anti-fading agents.Ingeza ama-polyphenols etiye ekudleni angagcina ukunambitheka kwangempela, ukuvimbela ukonakala nokushintsha umbala, ngomsebenzi wokuvimbela nokubulala amagciwane, okuzokwenza ngcono izindinganiso zokuhlanzeka kokudla.
2) Isetshenziswa emkhakheni wezokwelapha, futhi isetshenziselwa ukwelapha isifo senhliziyo, isifo sikashukela kanye nomdlavuza.
I-3) Isetshenziswa emkhakheni wezimonyo, i-EGCG iphethe umphumela wokulwa nokushwabana nokulwa nokuguga.Ukuvikela isikhumba ekukhanyeni kwelanga okuyingozi, okuzovimbela umdlavuza wesikhumba.
Izindlela zokukhipha ama-polyphenols etiye ikakhulukazi zifaka indlela yokuhlukanisa imvula, indlela yokuhlukanisa i-adsorption, indlela yokukhipha i-organic solvent, indlela yokukhipha izinga lokushisa eliphansi le-enzyme yokukhipha, indlela yokukhipha usawoti, izindlela ezintsha ezithuthukisiwe zihlanganisa i-supercritical solvent extraction.Lapha sethula indlela evame ukusetshenziswa kakhulu yokuhlukanisa usawoti we-calcium.Ngemuva kokuchotshozwa, amaqabunga etiye acwiliswa emanzini ashisayo ku-80 ℃ i-30min ku-kettle yokukhipha, ehlungiwe, ikhekhe lokuhlunga ligezwa ngamanzi amancane abilayo, isisombululo sokugeza sihlanganiswe ne-filtrate, nezinye izingxenye ezifana i-caffeine ingakhishwa ngemva kokuba ikhekhe lokuhlunga lomile.I-filtrate ithululelwa emkhunjini wezulu, futhi amanzi agcwele ama-lime, amanzi agcwele ama-lime kanye namanzi anosawoti agcwele engezwa ngesilinganiso esingaba ngu-1: 6: 5 we-filtrate: amanzi e-lime: amanzi anosawoti.Ngemuva kokuvuselela ngokugcwele, ingxube ivunyelwe ukuma imizuzu engu-30, ukuhlunga.Ikhekhe lesihlungi libe selifakwa kusifaki-asidi kanye no-0.5%~0.8% we-H2S04, lungisa i-pH engu-7.1~7.2, bese kusetshenziswa i-acetic acid noma i-citric acid ukulungisa inani le-pH libe ngu-7.0, linyakaziswa ngokuphelele, bese limelela I-30min, isihlungi, geza, i-filtrate yomiswa ukuze uthole umkhiqizo ophelile.
