Quercetin 95.0%

Quercetin yog ib hom flavonoid antioxidant uas muaj nyob rau hauv cov zaub mov cog, nrog rau cov nplooj ntsuab, txiv lws suav, txiv hmab txiv ntoo thiab zaub paj.Nws yog technically suav hais tias yog ib tug "cog pigment," uas yog vim li cas nws tau pom nyob rau hauv cov xim sib sib zog nqus, cov txiv hmab txiv ntoo-packed thiab veggies.
suav tias yog ib qho ntawm cov antioxidants ntau tshaj plaws hauv tib neeg cov zaub mov, quercetin plays ib qho tseem ceeb hauv kev sib ntaus sib tua dawb radical puas, cov teebmeem ntawm kev laus thiab o.Thaum koj tuaj yeem tau txais ntau quercetin los ntawm kev noj cov zaub mov noj qab haus huv, qee tus neeg kuj tau noj cov tshuaj quercetin rau lawv cov kev tiv thaiv muaj zog.

Raws li lub Department of Pathology thiab Diagnostics ntawm University of Verona hauv ltalis, quercetin thiab lwm yam flavonoids yog "anti-viral, anti-microbial, anti-inflammatory thiab anti-allergic agents" nrog lub peev xwm los qhia tau zoo nyob rau hauv ntau hom cell hauv ob leeg tsiaj thiab tib neeg.Flavonoid polyphenols muaj txiaj ntsig zoo tshaj plaws rau kev txo qis lossis txo qis txoj hauv kev thiab kev ua haujlwm.Quercetin yog suav tias yog qhov feem ntau diffused thiab paub qhov xwm txheej los ntawm flavonol muaj, uas qhia muaj zog tiv thaiv kab mob thiab mob tshwm sim los ntawm leukocytes thiab lwm yam intracellular signals.

Quercetin yog ib qho muaj zog antioxidant thiab muaj kev tiv thaiv kab mob, tiv thaiv cov kab mob ntawm tes thiab cov hlab ntsha los ntawm kev puas tsuaj ntawm cov dawb radicals.Nws txhim kho cov hlab ntsha muaj zog.Quercetin inhibits kev ua ntawm catechol-O-methyltransferase uas ua rau cov neurotransmitter norepinephrine.Cov nyhuv no tuaj yeem ua rau nce qib ntawm norepinephrine thiab nce kev siv hluav taws xob thiab roj oxidation.Nws kuj txhais tau hais tias quercetin ua raws li ib qho tshuaj tiv thaiv kab mob ua rau txo kev ua xua thiab mob hawb pob.Raws li ib qho antioxidant, nws txo qis LDL roj cholesterol thiab muaj kev tiv thaiv los ntawm kab mob plawv.Quercetin blocks ib qho enzyme uas ua rau tsub zuj zuj ntawm sorbitol, uas tau txuas rau paj hlwb, qhov muag, thiab lub raum puas hauv cov neeg mob ntshav qab zib.

Quercetin tuaj yeem cuam tshuam cov nyhuv ntawm tus neeg mob qog noj ntshav, inhibiting kev loj hlob ntawm malignant hlwb hauv vitro, inhibiting DNA, RNA, thiab protein synthesis ntawm Ehrlich ascites qog hlwb.
Quercetin muaj cov teebmeem ntawm inhibiting platelet aggregation thiab tso tawm cov nyhuv ntawm serotonin (5-HT) nrog rau inhibiting platelet aggregation txheej txheem uas yog induced los ntawm ADP, thrombin thiab platelet-activating factor (PAF) uas muaj zog inhibition nyhuv ntawm PAF.Tsis tas li ntawd, nws tuaj yeem ua rau inhibit thrombin-induced tso cov platelet 3H-5-HT ntawm luav.
(1) Intravenously ntxiv 0.5mmol / L quercetin (10ml / kg) poob siab tuaj yeem txo lub sijhawm ntawm arrhythmia hauv nas ntawm myocardial ischemia thiab rov ua dua, txo qhov tshwm sim ntawm ventricular fibrillation, thiab txo cov ntsiab lus ntawm MDA nrog rau kev ua haujlwm. ntawm xanthine oxidase hauv cov ntaub so ntswg ischemic myocardial thaum muaj kev tiv thaiv zoo ntawm SOD.Qhov no tuaj yeem cuam tshuam nrog kev cuam tshuam ntawm kev tsim cov txheej txheem ntawm myocardial oxygen dawb radical thiab tiv thaiv SOD lossis ncaj qha tshem tawm ntawm cov pa dawb radical hauv cov ntaub so ntswg myocardial.
(2) Kev soj ntsuam hauv vitro nrog quercetin thiab rutin ua ke tuaj yeem cuam tshuam cov platelet thiab thrombus adhered rau luav aorta endothelium nrog EC50 ntawm 80 thiab 500nmol / L, raws li.Hauv vitro kev soj ntsuam ntawm qhov concentration ntawm quercetin ntawm 50 ~ 500μmol / L tau pom tias nws tuaj yeem txhim kho cAMP qib hauv tib neeg platelet, txhim kho PGI2-vim kev txhim kho ntawm cAMP qib ntawm tib neeg platelet thiab inhibit ADP-induced platelet aggregation.Quercetin ntawm ib tug concentration ranged los ntawm 2 ~ 50μmol / L muaj ib tug concentration-dependent li cov nyhuv.Quercetin, ntawm qhov siab ntawm 300 μmol / L hauv vitro tuaj yeem tsis tsuas yog yuav luag tag nrho inhibit cov txheej txheem ntawm platelet aggregation vim yog platelet activating factor (PAF), tab sis kuj inhibit thrombin thiab ADP-induced platelet aggregation nrog rau inhibit qhov tso tawm ntawm luav platelet 3H-5HT induced los ntawm thrombin;Ib qho concentration ntawm 30 μmol / L tuaj yeem txo cov kua dej ntawm platelet membrane.
(3) Quercetin, ntawm qhov concentration ntawm 4 × 10-5 ~ 1 × 10-1g / ml, muaj cov nyhuv inhibitory ntawm kev tso tawm ntawm histamine thiab SRS-A nyob rau hauv lub ntsws ntawm ovalbumin-sensitized guinea npua ntsws;Ib qho concentration ntawm 1 × 10-5g / ml kuj muaj cov nyhuv inhibitory ntawm SRS-A induced ileum contraction ntawm guinea npua.Quercetin, ntawm qhov concentration ntawm 5 ~ 50μmol / L, muaj qhov concentration-dependent inhibitory nyhuv ntawm cov txheej txheem ntawm histamine tso tawm ntawm tib neeg basophilic leucocyte.Nws cov nyhuv inhibitory ntawm lub ileum contraction ntawm ovalbumin sensitized guinea npua kuj yog qhov concentration-dependent nrog IC50 ntawm 10μmol / L.Ib qho concentration ntawm 5 × 10-6 ~ 5 × 10-5mol L tuaj yeem cuam tshuam kev loj hlob ntawm cytotoxic T lymphocyte (CTL) nrog rau inhibit ConA-induced DNA synthesis.
