Procyanidins (OPC), dzina la sayansi yaku China, ndi mtundu wa bioflavonoids wokhala ndi mawonekedwe apadera a maselo. Imadziwika padziko lonse lapansi ngati antioxidant yothandiza kwambiri pakuchotsa ma free radicals m'thupi la munthu.
1. Free radical scavenging, antioxidant ndi anti-kukalamba
Ma radicals aulere amawononga nembanemba ya cell, zomwe zimapangitsa kuti mapindikidwe ndi kupasuka kwa cell membrane, kotero kuti selo silingathe kuyamwa zakudya kuchokera kunja, kapena kutulutsa zinyalala za metabolic mu cell, ndikutaya kukana mabakiteriya ndi ma virus. Pambuyo pa kuphulika kwa selo, madzi otayika a selo ndi zinyalala zimalowa mu selo, zomwe zimayambitsa zochitika zakunja monga kutupa, kupweteka, kufiira ndi kutupa. Maselo ochulukirachulukira amaphulika ndi apoptosis, zomwe zimapangitsa kuchepa ndi kuwonongeka kwa ntchito ya khungu, minofu, ziwalo zamkati ndi ziwalo zina. Ma radicals aulere ndi chimodzi mwazinthu zofunika zomwe zimayambitsa kukalamba kwa anthu komanso matenda ambiri. Pafupifupi 80% ~ 90% ya matenda okalamba ndi osokonekera amakhudzana ndi ma radicals aulere, kuphatikiza mawanga akuda, makwinya, chifuwa, ng'ala, khansa, matenda amtima ndi zina zotero. Kuphatikizika kwa tsiku ndi tsiku kwa ma polyphenols amphesa kumatha kuchotsa bwino ma radicals aulere ochulukirapo ndikupereka chitetezo cha maola 24 pama cell osiyanasiyana amunthu.
2. Kuzimiririka mawanga ndi whiten khungu
Kuchokera ku thupi: ndi kukula kwa msinkhu komanso kuipitsidwa kwa chilengedwe, thupi la munthu limatulutsa ma radicals ambiri aulere, zomwe zimapangitsa kuti pakhale vuto la kagayidwe kachakudya komanso kupanga lipofuscin kwambiri m'thupi. Njira yake yowonongeka imatsekedwa, ndipo kuchuluka kwa lipofuscin kumayikidwa mu mtima, chiwindi, ndulu, mapapo, impso, ubongo ndi maselo a mitsempha, kupanga mawanga a lipofuscin, ziwalo zowononga ndi kuchepa kwa ntchito; Lipofuscin imayikidwa m'maselo a khungu (makamaka khungu la nkhope ndi dzanja), kupanga madontho a pakhungu, chloasma, mawanga agulugufe ndi mawanga okalamba, zomwe zimakhudza kwambiri maonekedwe a odwala ndikupweteka kwambiri m'maganizo kwa odwala. Mphesa polyphenol proanthocyanidins imadziwika kuti 'most free radical scavenger'. Ikhoza kuwola lipofuscin, kuteteza ziwalo zosiyanasiyana ndikuchepetsa mawanga amtundu m'thupi. Kuphatikiza apo, mosiyana ndi ma antioxidants wamba, ma procyanidin amatha kuwoloka chotchinga chamagazi ndi ubongo ndikuteteza ubongo ndi mitsempha yamagazi ku ma radicals aulere.
Pakhungu: mpweya wodetsedwa, kuwala kwamphamvu kwa ultraviolet ndi makompyuta, zodzoladzola (zonunkhira, zoteteza, zopaka utoto) ndi zinthu zina zomwe zimayambitsa kubadwa kwa ma radicals akunja, zomwe zimapangitsa kuti kunja kwa khungu kuvutike kwambiri. . Munthawi ya kuukira kwaufulu komanso kuwonongeka kwa maselo, maselo ambiri amafa komanso kusokonezeka kwa metabolic, ndipo zonyansa zama cell sizingasunthike, zomwe zimapangitsa kuti pigment ikhazikike, kuchuluka kwa maselo atsopano kumachepetsedwa kwambiri (ma cell atsopano ndi ofunikira. zomwe zimapangitsa kuti khungu likhale lamphamvu). Mphesa proanthocyanidins sangathe mogwira kuchotsa ufulu ankafuna kusintha zinthu mopitirira mu thupi la munthu, komanso kulimbikitsa khungu kagayidwe, kudzipatula kuipitsidwa kwa chilengedwe ndi zodzikongoletsera kuwonongeka, kuwola melanin ndi kukwaniritsa zotsatira za whitening khungu. Procyanidin OPC ndi chilengedwe chotchinga dzuwa, chomwe chingalepheretse kuwala kwa ultraviolet kuwononga khungu. Kuwala kwa dzuwa ndi kuwala kwa ultraviolet kumatha kupha 50% ya maselo a khungu la munthu, koma ngati mutenga ma polyphenols a mphesa kuti atetezedwe, pafupifupi 85% ya maselo a khungu amatha kupulumuka imfa ndi "kudziteteza ku dzuwa".
3. Sungani kusungunuka kwa khungu ndikuchepetsa makwinya
Dermis ya khungu ndi ya connective minofu. Collagen ndi elastin zolimba zomwe zili mmenemo zimagwira ntchito yofunika kwambiri pakhungu lonse. Mphesa polyphenol proanthocyanidins amagwira ntchito wapawiri pakhungu: mbali imodzi, akhoza kulimbikitsa mapangidwe kolajeni yoyenera mtanda yolumikizira; Kumbali inayi, monga njira yabwino yopulumutsira mkangaziwisi waulere, imatha kuletsa "kuwoloka" kwa khungu, kuteteza mawonekedwe a makwinya ndi zipsera, ndikupangitsa khungu kukhala lofewa komanso losalala. Mphesa ya polyphenol proanthocyanidins imathanso kulepheretsa kupanga elastase yolimba, kuletsa ntchito yake, ndikuletsa ma radicals aulere kapena zovuta za elastase kuwononga mapuloteni olimba, kuti apititse patsogolo thanzi la khungu mkati, kuchepetsa matenda a khungu ndi makwinya, komanso kuchotsa zipsera.
4. PMS (premenstrual syndrome)
Mkazi aliyense sadzakhala wosazoloŵerana ndi PMS (premenstrual syndrome). Zizindikiro zambiri za PMS ndizo: kupweteka, kutupa m'mawere, mimba yosiyana, kutupa kwa nkhope, kupweteka kwa m'chiuno mosadziwika bwino, kunenepa kwambiri, kufooka kwa miyendo, kusakhazikika kwamaganizo, chisangalalo, kukwiya, kuvutika maganizo ndi mutu wa ubongo. Zizindikirozi zimachokera ku momwe thupi limayankhira pamlingo wa estrogen ndi progesterone m'thupi
