Imbuto zinzabibu ni ubwoko bwa polifenol ikurwa mu mbuto zinzabibu. Igizwe ahanini na procyanidine, catechine, epicatechine, aside gallic, gallate epicatechin hamwe na polifenol.

Ubushobozi bwa Antioxydeant
Imbuto y'imizabibu ikuramo ibintu bisanzwe. Nimwe muri antioxydants ikora neza ituruka ku bimera. Ikizamini cyerekana ko ingaruka za antioxydeant zikubye inshuro 30 ~ 50 za vitamine C na vitamine E.
ibikorwa
Procyanidine ifite ibikorwa bikomeye kandi irashobora kubuza kanseri mu itabi. Ubushobozi bwabo bwo gufata radicals yubusa mugice cyamazi irikubye inshuro 2 ~ 7 kurenza iya antioxydants rusange, nka α- Igikorwa cya tocopherol kirenze inshuro ebyiri.
gukuramo
Byagaragaye ko mu ngingo nyinshi z’ibimera, ibikubiye muri proanthocyanidine mu mbuto zinzabibu hamwe n’ibiti bya pinusi byari byo hejuru, kandi uburyo nyamukuru bwo kuvana Proanthocyanidine mu mbuto zinzabibu ni ugukuramo ibishishwa, gukuramo microwave, gukuramo ultrasonic no gukuramo CO2 ndengakamere. Imbuto yinzabibu proanthocyanidins ikuramo imyanda myinshi, ikeneye ubundi kwezwa kugirango irusheho kwera kwa proanthocyanidine. Uburyo bukoreshwa muburyo bwo kweza burimo gukuramo ibishishwa, gushungura membrane na chromatografiya.
Ubwinshi bwa Ethanol bwagize ingaruka zikomeye ku kigero cyo gukuramo imbuto zinzabibu proanthocyanidine, kandi igihe cyo gukuramo nubushyuhe nta ngaruka nini byagize ku gipimo cyo gukuramo imbuto zinzabibu proanthocyanidine. Ibipimo byiza byo gukuramo byari ibi bikurikira: kwibanda kuri Ethanol 70%, igihe cyo gukuramo 120 min, igipimo gikomeye-cyamazi 1:20.
Ubushakashatsi bwa static adsorption bwerekana ko igipimo kinini cya adsorption ya hpd-700 kuri proanthocyanidine ari 82,85%, hagakurikiraho da201, ni 82.68%. Hariho itandukaniro rito. Byongeye kandi, ubushobozi bwa adsorption yibi bisigarira byombi kuri proanthocyanidine nayo ni imwe. Mu kizamini cya desorption, da201 resin ifite igipimo kinini cya desorption ya procyanidine, ni 60.58%, mugihe hpd-700 ifite 50.83% gusa. Hamwe na adsorption hamwe nubushakashatsi bwa desorption, da210 resin yariyemeje kuba resin nziza ya adsorption yo gutandukanya procyanidine.
Binyuze mubikorwa byiza, mugihe intumbero ya proanthocyanidine ari 0.15mg / ml, umuvuduko wogutemba ni 1ml / min, 70% yumuti wa Ethanol ukoreshwa nka eluent, umuvuduko wamazi ni 1ml / min, naho ingano ya eluent ni 5bv, ibiyikuramo y'imbuto z'inzabibu proanthocyanidins zirashobora kwezwa mbere.
