Quercetin Dihydrate hmoov

Quercetin, raws li cov flavonoid ntau tshaj plaws, muaj ntau yam kev ua haujlwm lom neeg, tuaj yeem ua antioxidant, thiab ua lub luag haujlwm tseem ceeb hauv kev kho mob qog noj ntshav thiab kab mob plawv. Quercetin tsis tsuas yog koom nrog kev tiv thaiv oxidation hauv vitro thiab tuaj yeem tiv thaiv oxidative kev puas tsuaj rau DNA, tab sis kuj tiv thaiv cov ntaub so ntswg los ntawm oxidative kev puas tsuaj hauv vivo los ntawm kev txo cov concentration ntawm peroxide hauv cov ntaub so ntswg.

Cov mis mos molecular ntawm dihydrate yog C15H9O7 · 2H2O, daj koob siv lead ua (dilute ethanol), mp313 degree -314 degree (decomposition). Soluble nyob rau hauv kub ethanol (1: Chemicalbook23), txias ethanol (1:300), soluble nyob rau hauv methanol, ethyl acetate, glacial acetic acid, pyridine, thiab lwm yam., insoluble nyob rau hauv roj av ether, benzene, ether, chloroform, thiab yuav luag insoluble nyob rau hauv dej. .

Quercetin yog ib qho expectorant feem ntau siv hauv kev kho mob ntawm cov tshuaj suav tshuaj hauv kuv lub tebchaws. Cov khoom no muaj cov txiaj ntsig zoo expectorant thiab hnoos-relieving los, thiab kuj muaj qee yam antiasthmatic nyhuv. Nws tuaj yeem txo cov ntshav siab, txhim kho capillary tsis kam, thiab txo cov ntshav siab capillary. Nws muaj cov tshuaj pharmacological ntawm fragility, txo cov ntshav lipids, dilating coronary hlab ntsha, thiab ua rau cov ntshav coronary. Clinically, quercetin feem ntau yog siv rau bronchitis thiab phlegm o. Chemicalbook kuj muaj kev pab kho mob rau cov neeg mob uas muaj kab mob plawv thiab kub siab. Kev siv cov khoom no yuav ua rau lub qhov ncauj qhuav, kiv taub hau thiab kub hnyiab hauv lub plab, uas yuav ploj mus tom qab tso tseg cov tshuaj. Quercetin yog dav pom nyob rau hauv angiosperms, xws li liab tube tshuaj, miv qhov muag nyom, hlau-coated kub, roob liab, me-nplooj loquat, ntshav paj azalea, Zhaoshan dawb, Aidi tshuaj yej, thiab Apocynum. Nws yog glycosides. Yuan, qhov aglycone no feem ntau ua ke nrog qab zib kom muaj nyob rau hauv daim ntawv ntawm glycosides, xws li quercetin, rutin, hyperoside, thiab lwm yam.

Quercetin tuaj yeem inhibit platelet aggregation thiab tso tawm ntawm {{0}}hydroxytryptamine (5-HT). Nws muaj cov nyhuv inhibitory tseem ceeb ntawm platelet aggregation tshwm sim los ntawm ADP, thrombin thiab platelet activating factor (PAF), ntawm cov nyhuv inhibitory ntawm PAF yog qhov muaj zog tshaj plaws. , kuj tseem tuaj yeem cuam tshuam thrombin-induced 3H-5-HT tso tawm los ntawm luav platelets. (1) Kev txhaj tshuaj ntawm 10 ml / kg ntawm quercetin ntawm qhov siab ntawm 0.5 mmol / L tuaj yeem ua rau lub sijhawm arrhythmia ntawm myocardial ischemia-reperfusion hauv cov nas, txo qhov tshwm sim ntawm ventricular fibrillation, thiab txo cov ntsiab lus ntawm MDA hauv cov ntaub so ntswg myocardial. nyob rau hauv cheeb tsam ischemic perfusion thiab Xanthine oxidase kev ua, thiab nws cov kev tiv thaiv pom tseeb ntawm SOD, tej zaum yuav cuam tshuam rau inhibiting qhov tsim ntawm oxygen dawb radicals hauv myocardium thiab tiv thaiv SOD hauv cov ntaub so ntswg myocardial lossis ncaj qha scavenging oxygen dawb radicals. (2) Nyob rau hauv vitro Chemicalbook kev ntsuam xyuas ntawm quercetin thiab rutin tuaj yeem tawg platelet thrombus adhered rau luav aortic endothelium, thiab lawv EC50s yog 80 thiab 500 nmol / L raws li. Quercetin ntawm 50 mus rau 500 μmol / L tuaj yeem ua rau tib neeg platelet cAMP qib hauv kev kuaj hauv vitro. Nws tuaj yeem nce tib neeg platelet cAMP qib thiab inhibit ADP-induced human platelet aggregation los ntawm PGI2. Quercetin ntawm 2 mus rau 50 μmol / L muaj cov nyhuv concentration-dependent. Quercetin tuaj yeem yuav luag tag nrho inhibit platelet aggregation tshwm sim los ntawm platelet activating factor (PAF) hauv cov nas ntawm qhov siab ntawm 300 μmol / L hauv lub raj kuaj. Nws kuj inhibits platelet aggregation tshwm sim los ntawm thrombin thiab ADP. Nws kuj inhibits thrombin-induced 3H-5HT ntawm luav platelets. Nws muaj cov nyhuv inhibitory ntawm kev tso tawm; Ib qho concentration ntawm 30 μmol / L tuaj yeem txo qis cov kua dej ntawm cov nas platelets.

Cov khoom no muaj cov txiaj ntsig zoo expectorant thiab hnoos-relieving los, thiab muaj qee yam antiasthmatic nyhuv. Tsis tas li ntawd, nws muaj cov txiaj ntsig ntawm kev txo cov ntshav siab, txhim kho capillary tsis kam, txo cov capillary fragility, txo cov ntshav lipids, dilating coronary arteries, thiab ua rau cov ntshav coronary. Rau kev kho mob bronchitis. Nws kuj muaj kev pab kho mob rau cov neeg mob uas muaj kab mob plawv thiab ntshav siab.

Organic rhiab heev reagent, fluorescence ntsuas ntawm txhuas, photometric ntsuas ntawm hlau, tin thiab zirconium. Biochemical reagent, inhibitor ntawm mitochondrial adenosine triphosphatase. tshuaj kho mob. Sib tov nrog epichlorohydrin (3-chloro-1, 2-epoxypropane) los ua epoxy resin.
