(-) -Epicatechin (EC) (CAS: 490-46-0), i-antioxidant kanye nomkhiqizo wemvelo ovela itiye eluhlaza.
(-) -I-Epicatechin isitshalo semvelo se-flavanol compound, esincibilika emanzini nase-methanol.Ngokuqoqiwe yaziwa ngokuthi ama-catechin compounds ane-epigallocatechin gallate, i-epicatechin gallate, i-epicatechin gallate ne-epigallocatechin gallate, Futhi ama-catechin angama-isomers elinye nelinye.
Isakhiwo samangqamuzana (-) -Epicatechin sinamaqembu amaningi asebenzayo kanye nezindawo ezisebenzayo, ezingenza i-epicatechin ikhiqize ukusabela okuhlukahlukene kwe-phenolic.Ucwaningo lwesimanje lwezokwelapha luye lwabonisa ukuthi ama-flavonoid afana ne-epicatechin anemisebenzi yokulwa ne-oxidation, ukuxosha ama-radicals mahhala, ukuqinisa umzimba, ukulawula ukuzivikela komzimba nokunye.Lo mkhiqizo ukhishwa ikakhulukazi etiyeni.
(-) -I-Epicatechin iyingxenye eyinhloko yomphumela wetiye eliluhlaza.Ingasetshenziswa njengomuthi wokwelapha kanye nokuvimbela isifo senhliziyo, umdlavuza njll. Isixazululo saso samanzi esithambekele ekubeni ne-oxidation, esivame ukusetshenziselwa ama-anti-oxidants.Iphinde ibe nomsebenzi wokunciphisa ukungena kwama-capillaries, i-antidiarrheal, i-hemostasia, ama-antiviral, i-antimycotic, imelana ne-ACE kanye ne-prophylaxis peptic ulcers.
1. Isetshenziswa emkhakheni wokudla, isetshenziswa njenge-antioxidant yemvelo, i-antistaling ejenti, kanye nama-anti-fading agents.
