Ama-tannins (tannins) ayinhlanganisela ekhiqizwa izitshalo ngokwemvelo. Zingama-polyphenols futhi zingamakhemikhali asebenzayo kakhulu. Ama-tannin awancibiliki emanzini futhi anesisindo samangqamuzana ebangeni elingama-500 kuya ku-3000 Da. Imikhiqizo enokuqukethwe okuphezulu kwalezi zinhlanganisela inokunambitheka okunzima, okungajabulisi futhi ingaba yingozi.
Endabeni yezitshalo, ama-Tannins anomsebenzi wokuzivikela, anqande izilwane ezidla uhlaza. Phakathi kwezinye izinto, ama-tannins akhona emagxolweni e-oki, i-willow, i-spruce, i-chestnut, i-larch, amaqabunga e-walnut, i-sage, iwayini, itiye, amantongomane, ezithelo eziningi (njengama-blueberries, ama-strawberries, ama-raspberries, ama-cranberries, amagilebhisi, amahalananda, ama-apula), e-St. wort, cinquefoil, turnip rape, infusion cistus kanye nembewu yemidumba, nokunye okufana nokolweni, ushokoledi omnyama nokhokho.
Ama-tannins - ukuhlukaniswa
Sihlukanisa ama-tannins ngezinhlobo ezimbili:
- i-hydrolysing - enkabeni ye-molecule i-monosaccharide, amaqembu e-hydroxyl ahlanganiswe nezinsalela ze-gallic acid noma okuphuma kuyo; i-hydrolyzed kalula kuma-acids abuthakathaka kanye nezisekelo noma ama-enzyme;
- i-non-hydrolysing (i-condensed) - ayinayo i-saccharide ku-molecule, itholakala ezithelweni ezingavuthiwe kanye nembewu, okuthi ngaphansi kwethonya lokuvuthwa ihlukaniswe ibe yizinhlanganisela nama-molecule amancane.
Ama-tannins - izakhiwo
Ama-Tannins abonakala ngezinto eziningi ezizuzisa umzimba womuntu, kufaka phakathi:
- ehlisa ukucasuka,
- nciphisa ukulunywa nokushisa,
- babe ne-anti-inflammatory kanye ne-antibacterial properties,
- ukusekela umsebenzi wamasosha omzimba,
- vimbela ukungezwani komzimba nezinto ezithile.
Uma zithathwa ngomlomo, zinomphumela we-astringent kulwelwesi lwamafinyila, zivimbela ukungena kwazo, zivimbele, ngokwesibonelo, ukuphuma kwegazi emithanjeni ye-capillary (ikakhulukazi emgudwini wesisu).
Ngokusho kososayensi, ama-tannin angavikela kuzo zonke izinhlobo izicubufuthi futhi yehlise ijubane izinga amangqamuzana omdlavuza ahlukana ngalo. Bangasiza ukuguqula i-microflora yomlomo namathumbu, ukuqeda izinto eziphilayo ze-pathogenic. Izakhiwo ezinamandla ze-antioxidant zama-tannins zinciphisa ama-radicals mahhala alimaza izakhiwo zamaseli ayisisekelo. Bavimbela i-lipid peroxidation kanye nokuphindaphindeka kwe-HIV. Futhi banomphumela wokulwa ne-carcinogenic. Ama-tannins e-hydrolysing kalula aphulwa emgudwini wokugaya ukudla. Ama-tannin nawo asetshenziselwa ukulwa nemiphumela yobuthi be-alkaloid.
Ama-tannin nawo asetshenziselwa ukwelapha isikhumba sezilwane. Umsebenzi we-antioxidant wama-tannins nawo ubalulekile ekwandiseni impilo yeshalofu yokudla. Isibonelo yiwayini elibomvu, okuthi, ngenxa yama-tannins, lingavuthwa iminyaka eminingi futhi alinayo i-oxidized. Ngenxa yokulula ukuhlanganisa ama-tannins nama-ion ensimbi, asetshenziselwa ukuthola odayi.
Ukusetshenziswa ngokweqile kwezitshalo ezicebile ngama-tannins kuvimbela ukumuncwa, phakathi kokunye, amavithamini, ama-macro- kanye nama-microelements emgudwini wamathumbu. Ama-tannins angewona ama-hydrolysing abola emgudwini wamathumbu abe yizinhlanganisela ezinobuthi, okubangela ubuthi, ngakho-ke ukudla izithelo ezingavuthiwe kufanele kugwenywe.
