Quercetin 95.0%

Quercetin ndi mtundu wa flavonoid antioxidant umene umapezeka mu zakudya zomera, kuphatikizapo masamba masamba, tomato, zipatso ndi broccoli.Mwaukadaulo amaonedwa ngati "pigment ya chomera," chifukwa chake imapezeka mu zipatso zamitundu yozama, zodzaza ndi michere ndi masamba.
quercetin imatengedwa kuti ndi imodzi mwazambiri zowononga antioxidant m'zakudya za anthu, imagwira ntchito yofunika kwambiri polimbana ndi kuwonongeka kwakukulu kwaufulu, zotsatira za ukalamba ndi kutupa.Ngakhale mutha kupeza quercetin wambiri podya zakudya zopatsa thanzi, anthu ena amatenganso zowonjezera za quercetin chifukwa champhamvu yawo yotsutsa-kutupa.

Malinga ndi dipatimenti ya Pathology and Diagnostics ku yunivesite ya Verona ku Italy, quercetin ndi ma flavonoids ena ndi "anti-viral, anti-microbial, anti-inflammatory and anti-allergic agents" omwe amatha kuwonetsedwa bwino m'maselo osiyanasiyana. nyama ndi anthu.Flavonoid polyphenols ndiwothandiza kwambiri pakuchepetsa kapena kupondereza njira zotupa ndi ntchito.Quercetin imatengedwa kuti ndi flavonol yofalikira kwambiri komanso yodziwika bwino yochokera ku chilengedwe, yomwe ikuwonetsa zotsatira zamphamvu pa chitetezo chamthupi ndi kutupa komwe kumayambitsidwa ndi ma leukocyte ndi zizindikiro zina za intracellular.

Quercetin ndi antioxidant wamphamvu ndipo imakhala ndi anti-yotupa, imateteza ma cell ndi mitsempha yamagazi ku zotsatira zowononga za ma free radicals.Imalimbitsa mphamvu ya mtsempha wamagazi.Quercetin imalepheretsa ntchito ya catechol-O-methyltransferase yomwe imaphwanya neurotransmitter norepinephrine.Izi zitha kupangitsa kuti norepinephrine achuluke komanso kuwonjezereka kwa ndalama zogwiritsira ntchito mphamvu komanso okosijeni wamafuta.Zimatanthauzanso kuti quercetin imakhala ngati antihistamine yomwe imatsogolera ku mpumulo wa chifuwa ndi mphumu.Monga antioxidant, imachepetsa cholesterol ya LDL ndikuteteza ku matenda amtima.Quercetin imatsekereza enzyme yomwe imatsogolera ku kudzikundikira kwa sorbitol, komwe kumalumikizidwa ndi kuwonongeka kwa mitsempha, maso, ndi impso mwa odwala matenda ashuga.

Quercetin akhoza kwambiri ziletsa zotsatira za khansa-kulimbikitsa wothandizira, kuletsa kukula kwa zilonda maselo m'galasi, kuletsa DNA, RNA, ndi kaphatikizidwe mapuloteni a Ehrlich ascites chotupa maselo.
Quercetin imakhala ndi zotsatira zoletsa kuphatikizika kwa mapulateleti komanso kutulutsa kwa serotonin (5-HT) komanso kuletsa kuphatikizika kwa mapulateleti komwe kumayambitsidwa ndi ADP, thrombin ndi platelet-activating factor (PAF) yomwe imakhala ndi zoletsa zamphamvu kwambiri. PAF.Kuphatikiza apo, imathanso kulepheretsa thrombin-induced kutulutsidwa kwa mapulateleti 3H-5-HT a kalulu.
(1) Kuonjezera mtsempha wa 0.5mmol/L quercetin (10ml/kg) kutsika mwanzeru kumatha kufupikitsa kwambiri nthawi ya arrhythmia mu mbewa za myocardial ischemia ndi reperfusion, kuchepetsa kuchuluka kwa minyewa yamitsempha yamagazi, ndikuchepetsa zomwe zili mu MDA komanso ntchito. xanthine oxidase mkati mwa ischemic myocardial minofu pomwe imakhala ndi chitetezo chochuluka pa SOD.Izi zikhoza kukhala zokhudzana ndi kulepheretsa mapangidwe a myocardial oxygen free radical and protection of SOD kapena mwachindunji scavenging wa radical free oxygen mu myocardial minofu.
(2) Kukhala ndi in vitro assay yokhala ndi quercetin ndi rutin kukhala limodzi kumatha kumwaza mapulateleti ndi thrombus yotsatiridwa ndi kalulu aorta endothelium yokhala ndi EC50 ya 80 ndi 500nmol/L, motsatira.Mayeso a in vitro a kuchuluka kwa quercetin pa 50 ~ 500μmol/L awonetsa kuti amatha kusintha mulingo wa cAMP mkati mwa kupatsidwa zinthu za m'mwazi, kupititsa patsogolo kuwongolera kwa PGI2 kwa cAMP ya mapulateleti aumunthu ndikuletsa kuphatikizika kwa mapulateleti a ADP.Quercetin pa ndende kuyambira 2 ~ 50μmol/L ali ndi ndende amadalira kukulitsa zotsatira.Quercetin, pa ndende ya 300 μmol/L mu m'galasi sangalepheretse kuphatikizika kwa mapulateleti chifukwa cha kupatsidwa zinthu za m'mwazi (PAF), komanso kuletsa kuphatikizika kwa thrombin ndi ADP-induced platelet aggregation komanso kuletsa kutulutsidwa kwa mapulateleti. kalulu kupatsidwa magazi 3H-5HT opangidwa ndi thrombin;Kuphatikizika kwa 30 μmol/L kumatha kuchepetsa kwambiri madzi a m'magazi.
