(-) -Epigallocatechin Gallate Hydrate (EGCG Hydrate) (CAS: 989-51-5), chotsitsa cha tiyi wobiriwira, ndi polyphenol catechin antioxidant yamphamvu yomwe imapezeka mu tiyi wobiriwira, ndi flavonoid yamphamvu ya polyphenolic yomwe imapezeka ngati chigawo cha tiyi.Imawonetsa antioxidant, antimutagenic, antitumor ndi anti-inflammatory properties, motero imathandizira pazochitika zopindulitsa pa thanzi.Imapeza ntchito yomwe ingagwiritsidwe ntchito ngati mankhwala opangira mankhwala, zodzoladzola, ndi zakudya.
(-) - Epigallocatechin Gallate, katekisimu wamkulu wowerengera 59% ya makatekini onse mu tiyi wobiriwira, ndi antioxidant wamphamvu komanso antiangiogenic ndi antitumor agent.EGCG idaphunziridwa chifukwa cha gawo lake pakuletsa mitundu ingapo ya khansa, kuphatikizapo chiwindi, m'mimba, khungu, mapapo, mammary gland ndi khansa ya m'matumbo.Zotsatira za kafukufuku zikuwonetsa kuti egcg imatha kuyambitsa apoptosis, kulimbikitsa kukula kwa maselo ndikuletsa carcinogenesis pokhudza njira zotumizira ma sign.
Ntchito:
1) EGCG imatha kuchepetsa kuthamanga kwa magazi, shuga wamagazi, lipids.
2) EGCG ili ndi ntchito yochotsa ma radicals ndi anti-kukalamba.
3) EGCG ikhoza kupititsa patsogolo chitetezo cha mthupi komanso kupewa chimfine.
4) EGCG ili ndi ntchito yotsutsa-radiation, anti-cancer, yolepheretsa kuwonjezeka kwa maselo a khansa.Ndi ntchito yamphamvu yolimbana ndi xxidation, imatha kuthetsa ma radical aulere amthupi ndikukana kusintha kwa chotupa, kukalamba, kutupa, kachilombo ndi zina.
5) EGCG imagwiritsidwa ntchito polimbana ndi mabakiteriya, ndi ntchito yotseketsa komanso kununkhira.
6) Kupititsa patsogolo kagayidwe kazakudya ndi mafuta oxidation.
7) EGCG chimagwiritsidwa ntchito m'munda wa zakudya, mankhwala ndi tsiku ntchito mankhwala mankhwala.
8) EGCG imathanso kupewa ndikuchiza chotupa choyipa, hyperlipemia, arteriosclerosis, thrombosis yaubongo, matenda a shuga ndi obisity etc.
Ntchito:
1) Yogwiritsidwa ntchito m'munda wa chakudya, EGCG imagwiritsidwa ntchito ngati antioxidant, antistaling agent, ndi anti-fading agents.Imawonjezera ma polyphenols a tiyi muzakudya amatha kukhalabe ndi kukoma koyambirira, kuteteza ziphuphu ndi kusinthika, ndi ntchito yoletsa ndi kupha mabakiteriya, zomwe zingapangitse kuti zakudya zizikhala bwino.
2) Amagwiritsidwa ntchito pazamankhwala, amagwiritsidwanso ntchito pochiza matenda amtima, shuga ndi khansa.
3) Yogwiritsidwa ntchito m'munda wa zodzikongoletsera, EGCG ili ndi zotsatira zotsutsana ndi makwinya ndi zotsutsana ndi ukalamba.Kuteteza khungu ku dzuwa, zomwe zingateteze khansa yapakhungu.
Njira zochotsera tiyi wa tiyi wa polyphenols kuchokera ku tiyi makamaka zimaphatikizapo njira yolekanitsa mvula, njira yolekanitsa ma adsorption, njira yochotsera zosungunulira za organic, njira yochotsera ma enzyme, njira yotulutsira mchere, njira zatsopano zopangidwira zimaphatikizapo kutulutsa kosungunulira kopitilira muyeso.Apa tikuwonetsa njira yolekanitsa mchere wa calcium yomwe imagwiritsidwa ntchito kwambiri.Pambuyo kuphwanya, masamba tiyi ankawaviika m'madzi otentha pa 80 ℃ kwa 30min mu ketulo m'zigawo, amasefedwa, keke fyuluta ndi kutsukidwa ndi pang'ono madzi otentha, ndi kutsuka njira pamodzi ndi filtrate, ndi zigawo zina monga. caffeine ikhoza kutulutsidwa pambuyo pouma keke ya fyuluta.Filtrate imatsanuliridwa mu chotengera cha mpweya, ndipo madzi odzaza laimu, madzi a laimu odzaza ndi madzi amchere odzaza amawonjezedwa pa chiŵerengero cha 1: 6: 5 ya filtrate: madzi a mandimu: madzi amchere.Pambuyo poyambitsa kwathunthu, kusakaniza kumaloledwa kuima kwa 30 min, kusefera.Keke ya fyulutayo inayikidwa mu acidifier ndi 0.5% ~ 0.8% ya H2S04, kusintha pH ya 7.1 ~ 7.2, ndiyeno gwiritsani ntchito asidi acetic kapena citric acid kuti musinthe pH mtengo kukhala 7.0, wogwedezeka kwathunthu, ndiyeno muyimire. 30min, fyuluta, sambani, fyulutayo idawumitsidwa kuti ipeze chomaliza.
