Procyanidins hmoov

Hauj lwm lawm

Khoom Taw Qhia:

procyanidins hmoov yog cov tswv cuab ntawm proanthocyanidin (los yog condensed tannins) chav kawm ntawm flavonoids. Lawv yog oligomeric compounds, tsim los ntawm catechin thiab epicatechin molecules. Lawv tawm los cyanidin thaum depolymerized nyob rau hauv oxidative mob.

Cov txiaj ntsig:

Tib neeg lub cev raug tsim txom los ntawm cov dawb radicals (oxidants). Txhua lub cell hauv lub cev ntsib cov dawb radical tawm tsam ntau txhiab zaus txhua hnub. Dawb radicals ua rau cellular oxidation.

Oxidation yog hais txog cov txheej txheem tshuaj uas ua rau kev hloov hluav taws xob ntawm cov cellular ruaj khov (feem ntau yog fatty acids hauv cell membranes) thiab oxidizing tshuaj. Cov txheej txheem ntawm oxidation, nyob rau hauv lem, tsim ntau oxidizing tus neeg sawv cev. Qhov no catalyzes ib qho rov ua dua cov tshuaj tiv thaiv uas tuaj yeem ua rau muaj kev puas tsuaj ntawm cellular ntau ntxiv.

Cov tshuaj tiv thaiv oxidant ua kom khawb lub cev, nrhiav cov dawb radical electrons. Antioxidants tiv thaiv dawb radical kev puas tsuaj los ntawm kev tshem tawm cov intermediaries uas haum oxidative puas tsuaj. Phytonutrient polyphenols, zoo li procyanidins, paub tias muaj zog antioxidants.

Siv cov tshuaj procyanidin niaj hnub zoo li Pine Bark Extract tuaj yeem txhim kho lub cev tiv thaiv kev puas tsuaj oxidative, yog li txo cov kev pheej hmoo rau ntau yam kab mob thiab muaj feem cuam tshuam rau kev laus.

Procyanidins hmoov Daim ntawv thov:

Daim ntawv thov pleev xim:

Hauv daim tawv nqaij, proanthocyanidins muaj cov tshuaj tshwj xeeb thiab kev ua haujlwm ntawm lub cev thiab ua si ntau lub luag haujlwm hauv cov khoom tu tawv nqaij, xws li kev tiv thaiv kev laus, tiv thaiv ultraviolet, tiv thaiv hluav taws xob, ntxuav hniav dawb, moisturizing, thiab lwm yam. ntau yam. nyhuv.

Anti-wrinkle nyhuv

Lub cim ntawm wrinkles yog ib tug complex phenomenon. Los ntawm qhov kev xav ntawm lub cev, nws feem ntau cuam tshuam nrog kev sib txuas thiab degradation ntawm daim tawv nqaij proteins thiab cov ntaub so ntswg sib txuas. Cov nyhuv anti-wrinkle ntawm proanthocyanidin yog raws li nws lub peev xwm los tswj collagen synthesis; inhibit elastase; pab lub cev tiv thaiv collagen thiab txhim kho daim tawv nqaij elasticity; txhim kho daim tawv nqaij' kev noj qab haus huv ncig. Yog li kom zam los yog txo qhov tsim ntawm wrinkles

Sunscreen thiab whitening effect

Feem ntau ntawm cov tshuaj pleev thaiv hnub thiab tshuaj pleev xim dawb uas tau tshaj tawm yog cov khoom lag luam oily, uas ua rau cov tawv nqaij khaus hauv zos thiab txawm tias muaj cov teebmeem carcinogenic. Yog li ntawd, nws yog ib qho tseem ceeb heev los tshuaj xyuas cov tshuaj tiv thaiv dej-soluble sunscreen thiab whitening agents nrog ultraviolet absorbing nyhuv los ntawm cov khoom ntuj. Oligomeric proanthocyanidins yog ntuj ntshiab, dej-soluble, thiab muaj zog UV nqus ntawm 280nm. Nws tuaj yeem cuam tshuam kev ua haujlwm ntawm tyrosinase; nws tuaj yeem txo cov qauv o-phthaloquinone ntawm melanin rau hauv cov qauv phenolic kom ploj cov xim; Nws tuaj yeem inhibit Maillard cov tshuaj tiv thaiv vim yog cov amino pawg ntawm cov protein thiab cov amino pawg ntawm nucleic acid, thiab inhibit lipofuscin, tsim cov hnub nyoog me me. Nws tuaj yeem muaj kev sib koom ua ke nrog cov vitamin Vc lossis VE. Cov yam ntxwv ntawm oligomeric proanthocyanidins ua rau nws txoj haujlwm tseem ceeb hauv cov tshuaj pleev thaiv hnub txawv teb chaws thiab tshuaj pleev ib ce.

Astringent thiab moisturizing nyhuv

Cov nyhuv astringent ntawm proanthocyanidin ua rau cov tshuaj pleev ib ce uas muaj proanthocyanidin muaj adhesion zoo rau ntawm daim tawv nqaij nyob rau hauv cov dej tsis zoo thiab tuaj yeem txo qhov pores loj. Cov qog hws o, ua rau cov tawv nqaij xoob xoob, zawm, thiab txo cov tawv nqaij kom pom qhov muag pom. Cov nyhuv moisturizing ntawm proanthocyanidins yog raws li polyhydroxyl qauv ntawm proanthocyanidins, uas yog ib qho yooj yim mus nqus noo noo nyob rau hauv cov huab cua; proanthocyanidins tuaj yeem sib xyaw nrog polysaccharides (hyaluronic acid), proteins, lipids (phospholipids), peptides, thiab lwm yam.

Kev tiv thaiv hluav taws xob

Txoj kev xav ntawm dawb radicals yog lub hauv paus theoretical ntawm kev puas tsuaj hluav taws xob. Tom qab lub cev raug hluav taws xob, endogenous dawb radicals raug tsim, uas tuaj yeem ua rau kev puas tsuaj xws li lipid peroxidation. Cov qauv polyhydroxy ntawm grape noob extract proanthocyanidins ua rau nws muaj zog ntawm kev tshem tawm cov dawb radicals thiab inhibiting oxidative puas.
