Procyanidins (OPC), lub npe tshawb fawb Suav, yog ib hom bioflavonoids nrog cov qauv molecular tshwj xeeb. Nws yog thoob ntiaj teb lees paub tias yog qhov zoo tshaj plaws ntuj antioxidant rau scavenging dawb radicals hauv tib neeg lub cev.
1. Dawb radical scavenging, antioxidant thiab anti-aging
Dawb radicals rhuav tshem cov cell membrane, ua rau deformation thiab rupture ntawm cell membrane, thiaj li hais tias lub cell tsis tuaj yeem nqus cov khoom noj khoom haus los ntawm sab nraud, thiab tsis tshem tawm cov metabolic pov tseg hauv lub cell, thiab poob cov kab mob thiab cov kab mob. Tom qab cell rupture, cov kua cell uas nchuav thiab cov khib nyiab nkag mus rau hauv qhov chaw ntawm tes, ua rau muaj kev cuam tshuam sab nraud xws li mob, mob, liab thiab o. Ntau thiab ntau lub hlwb rupture thiab apoptosis, uas ua rau poob thiab degradation ntawm daim tawv nqaij, nqaij, sab hauv thiab lwm yam ntaub so ntswg. Dawb radicals yog ib qho tseem ceeb ua rau tib neeg kev laus thiab ntau yam kab mob. Txog 80% ~ 90% ntawm cov laus thiab cov kab mob degenerative muaj feem xyuam rau cov dawb radicals, nrog rau cov tawv nqaij tsaus nti, wrinkles, ua xua, cataracts, mob cancer, kab mob plawv thiab lwm yam. Txhua hnub ntxiv ntawm txiv hmab txiv ntoo polyphenols tuaj yeem tshem tawm cov dawb radicals ntau dhau thiab muab kev tiv thaiv 24-teev rau ntau lub hlwb ntawm tib neeg.
2. Fade me ntsis thiab whiten daim tawv nqaij
Los ntawm lub cev: nrog kev loj hlob ntawm lub hnub nyoog thiab kev ua qias tuaj ntawm ib puag ncig, tib neeg lub cev tsim cov dawb radicals ntau, uas ua rau muaj kev cuam tshuam ntawm metabolic thiab ntau dhau ntawm lipofuscin hauv lub cev. Nws txoj kev decomposition raug thaiv, thiab ntau npaum li cas ntawm lipofuscin tso rau hauv lub plawv, daim siab, tus po, ntsws, lub raum, hlwb thiab vascular hlwb, tsim lipofuscin me ntsis, ua rau lub cev puas tsuaj thiab kev ua haujlwm poob qis; Lipofuscin yog tso rau hauv cov tawv nqaij hlwb (tshwj xeeb tshaj yog cov tawv nqaij ntawm lub ntsej muag thiab tes), tsim cov tawv nqaij pob, chloasma, npauj npaim me ntsis thiab senile me ntsis, uas cuam tshuam rau cov tsos mob ntawm cov neeg mob thiab ua rau mob siab rau cov neeg mob. Grape polyphenol proanthocyanidins yog lub npe hu ua 'dawb dawb radical scavenger tshaj plaws'. Nws tuaj yeem decompose lipofuscin, tiv thaiv ntau yam kabmob thiab dilute xim xim ntawm lub cev. Tsis tas li ntawd, tsis zoo li cov antioxidants zoo tib yam, procyanidins tuaj yeem hla cov hlab ntsha-hlwb thiab tiv thaiv lub hlwb thiab cov hlab ntsha los ntawm cov dawb radicals.
Los ntawm qhov chaw ntawm daim tawv nqaij: huab cua qias neeg, muaj zog ultraviolet thiab hluav taws xob hauv computer, tshuaj pleev ib ce (spices, preservatives, pigments) thiab lwm yam yog lub hauv paus ua rau tiam ntawm exogenous dawb radicals, uas kuj ua rau sab nrauv ntawm daim tawv nqaij raug kev tsim txom ntau dua. . Nyob rau hauv tus txheej txheem ntawm kev tawm tsam dawb radicals thiab kev puas tsuaj ntawm cov hlwb, ntau lub hlwb tuag thiab cov kab mob metabolic, thiab cov impurities hauv hlwb tsis tuaj yeem metabolized, ua rau pigment deposition, cov xov tooj ntawm cov hlwb tshiab tau txo qis heev (cov hlwb tshiab yog ib qho tseem ceeb. qhov tseem ceeb hauv kev tswj cov tawv nqaij vitality). Grape proanthocyanidins tuaj yeem tsis tsuas yog tshem tawm cov dawb radicals hauv tib neeg lub cev, tab sis kuj txhawb cov tawv nqaij metabolism, cais cov pa phem ib puag ncig thiab kev puas tsuaj rau cov tshuaj pleev ib ce, decompose melanin thiab ua tiav cov nyhuv ntawm cov tawv nqaij dawb. Procyanidin OPC yog lub hnub ci ntuj npog cov neeg sawv cev, uas tuaj yeem tiv thaiv ultraviolet rays los ntawm kev puas tsuaj ntawm daim tawv nqaij. Hnub ci thiab ultraviolet rays tuaj yeem tua 50% ntawm tib neeg cov tawv nqaij, tab sis yog tias koj noj cov txiv hmab txiv ntoo polyphenols rau kev tiv thaiv, li ntawm 85% ntawm cov tawv nqaij muaj peev xwm ciaj sia tuag thiab zoo 'tiv thaiv hnub'.
3. Ua kom tawv nqaij elasticity thiab txo wrinkles
Lub dermis ntawm daim tawv nqaij belongs rau cov ntaub so ntswg. Cov collagen thiab tawv elastin muaj nyob rau hauv nws ua lub luag haujlwm tseem ceeb hauv tag nrho cov qauv ntawm daim tawv nqaij. Grape polyphenol proanthocyanidins ua si ob lub luag haujlwm hauv daim tawv nqaij: ntawm ib sab, nws tuaj yeem txhawb kev tsim ntawm tsim nyog cross-linking ntawm collagen; Ntawm qhov tod tes, raws li ib qho txiaj ntsig zoo ntawm cov dawb radical scavenger, nws tuaj yeem tiv thaiv "dhau hla" ntawm daim tawv nqaij, tiv thaiv cov tsos ntawm daim tawv nqaij wrinkles thiab nti, thiab ua rau daim tawv nqaij mos thiab du. Grape polyphenol proanthocyanidins tseem tuaj yeem tiv thaiv kev tsim cov tawv elastase, inhibit nws cov haujlwm, thiab tiv thaiv dawb radicals los yog tawv elastase los ntawm degrading nyuaj protein, thiaj li mus rau sab hauv txhim kho kev noj qab haus huv ntawm daim tawv nqaij, txo cov kab mob ntawm daim tawv nqaij thiab wrinkles, thiab txawm tshem tawm nti.
4. PMS (premenstrual syndrome)
Txhua tus poj niam yuav tsis paub nrog PMS (premenstrual syndrome). Cov tsos mob ntawm PMS yog: mob, lub mis o, lub plab tsis sib luag, lub ntsej muag edema, tsis paub meej ntawm lub plab, qhov hnyav nce, ceg tsis ua haujlwm, kev xav tsis txaus ntseeg, zoo siab, chim siab, kev nyuaj siab thiab mob taub hau. Cov tsos mob no tshwm sim los ntawm cov lus teb ntawm lub cev ntawm lub cev mus rau qib estrogen thiab progesterone hauv lub cev.
