Taw qhia
Quercetin yog flavonol compound uas tau dav dav hauv cov cog ntoo thiab muaj ntau yam kev ua haujlwm lom.
Lub rutin (rutin) ntawm quercetin tau faib ua qhov dav, thiab cov ntsiab lus yog siab, xws li cov ntsiab lus ntawm Sophora japonica txog ntau tshaj 20%. Rutin yog rho tawm los ntawm Sophora japonica lub paj tawg, thiab tom qab ntawd tom qab ua kua qaub hydrolysis tau txais cov hmoov quercetin.

Cov hmoov daj (methanol), nws cov dihydrate yog daj zoo li muaju.
Nws dhau los ua dej tsis txaus ntawm 95 ~ 97 ° C, nrog lub siab yaj ntawm 313 ~ 314 ° C (ua kom tsis qab).
Nws yog soluble hauv kub ethanol (1:23), txias ethanol (1: 300), soluble hauv methanol, ethyl acetate, glacial acetic acid, pyridine, thiab lwm yam, insoluble hauv roj av ether, benzene, ether, chloroform, thiab yuav luag insoluble. hauv dej.
Cov kua tshuaj aqueous alkaline yog daj, thiab cov tshuaj ethanol qab qab heev. Hauv qab ultraviolet teeb, xiav fluorescence tshwm. Ntxiv AlCl3 ethanol tov ua daj-ntsuab fluorescence, thiab cov tshuaj tiv thaiv hydrochloric acid-magnesium hmoov tshwm sim liab. [3]
Quercetin yog flavonol compound. Flavonoids feem ntau muaj nyob rau hauv daim ntawv ntawm glycosides. Vim ntau hom thiab txoj haujlwm ntawm cov sib txuas glycoside ntau yam ntawm flavonoid glycosides tau tsim. Dab tsi ua rau flavonoid glycosides feem ntau yog monosaccharides. Flavonols muaj cov dej ua tsis tau zoo, thaum lawv cov glycosides muaj ntau cov dej hauv dej.
Kev faib khoom ntuj
Quercetin yog dav nyob rau hauv cov tawv ntoo, paj, nplooj, buds, noob, thiab cov txiv hmab txiv ntoo ntawm ntau cov nroj tsuag, feem ntau nyob hauv daim ntawv ntawm glycosides, xws li rutin, quercetin, hyperoside, thiab lwm yam.
Quercetin tuaj yeem tiv taus cov dawb radicals, ib puag ncig lossis ntes dawb radicals los tiv thaiv lipid peroxidation hauv lub cev; nws tuaj yeem ncaj qha inhibit qog, thiab zoo tshaj tawm kev tawm tsam thiab mob qog ntshav; nws kuj tseem muaj cov kabmob tua, tiv thaiv mob, tiv thaiv ua xua, thiab tiv thaiv tus mob ntshav qab zib muaj teeb meem. Kev siv roj ntsha muaj zog. Tsis tas li ntawd, quercetin muaj cov txiaj ntsig ntawm kev txo cov ntshav siab, txhim kho capillary tsis kam, txo capillary fragility, txo cov ntshav lipids, txhim kho cov hlab ntsha coronary, nce ntshav coronary ntshav txaus, thiab lwm yam. Cov. Quercetin yog non-toxic, yog li nws yog qhov tseem ceeb rau kev kho thiab tiv thaiv mob qog noj ntshav, kev laus, thiab cov kab mob plawv, thiab muaj cov txiaj ntsig zoo ntawm kev loj hlob.
Muaj nuj nqi
Saib lub ntsab lug ntawm cov kev tshawb fawb tam sim no, nws muaj kev tiv thaiv oxidation, los tiv thaiv, tiv thaiv, tiv thaiv qog, tiv thaiv qog, hypoglycemic, lipid-qis qis, immunomodulation thiab lwm yam kev ua haujlwm lom thiab ntau cov tshuaj pharmacological. Nws muaj txiaj ntsig zoo rau kev kho mob ntawm cov kab mob, kev kis tus kab mob, hlav, mob ntshav qab zib, Ob qho hyperlipidemia thiab kev tiv thaiv kab mob hauv lub cev muaj cov kab mob tseem ceeb heev.
Yuav tsim khoom li cas?
Cov txheej txheem kev npaj ntawm quercetin suav nrog kev rho tawm thiab sib cais, acid hydrolysis, kev hloov kho enzymatic, thiab lwm yam, ntawm cov enzymatic transformation yog qhov tseeb tshaj.
Ntuj rho tawm thiab sib cais
Txij li cov ntsiab lus ntawm quercetin hauv cov nroj tsuag tsuas yog ob peb txhiab mus rau ob peb kaum txhiab, thiab kev rho tawm thiab sib cais yog qhov nyuaj thiab raug nqi ntau, kev tsim cov quercetin ncaj qha los ntawm cov nroj tsuag tsis yog qhov tseeb. Tab sis hauv kev txheeb xyuas, kev txheeb xyuas cov flavonoids lossis npaj cov ntshiab piv txwv rau kev tshawb xyuas, quercetin rho tawm thiab cais siv tshuab yuav tsum siv.
Acid hydrolysis
Cov txheej txheem rho tawm ntawm rutin tsuas yog suav nrog alkaline extraction thiab acid acid nag lossis daus, organic kuab tshuaj tawm, thiab ntsw. Ntawm lawv, alkaline extraction thiab acid nag lossis daus yog qhov ua tau zoo tshaj plaws. Xaiv lub 0.05% NaOH tshuaj kom npau li 20 feeb, lim nws thaum kub kub, thiab rho tawm 4 zaug hauv tib txoj kev kom tau txais kev daws teeb meem alkali ntawm rutin, ntxiv cov kua qaub ua kom nws nag lossis daus, thiab tom qab ntawd ntxiv acid rau hydrolyze tom qab pom kom tau dej-insoluble quercetin. Lim, ntxuav nrog dej, thiab qhuav kom tau insoluble quercetin.
Enzyme hloov txoj kev
Enzymatic hydrolysis ntawm rutin yog siv los npaj ntau ntawm quercetin monomer nrog cov ntsiab lus tsawg dua hauv cov nroj tsuag. Lub sijhawm ua haujlwm yog yooj yim thiab nyab xeeb. Cov txheej txheem tag nrho yog kev lag luam thiab siv tau, nrog rau cov txiaj ntsig loj, tsim nyog rau kev tsim khoom lag luam, thiab cov khoom ntshiab huv yog> 90%, uas tuaj yeem ua tau raws li cov kev xav tau ntawm cov zaub mov thiab chaw soj ntsuam. Yog li ntawd, kev hloov pauv enzymatic tsis ntseeg yog txoj kev npaj cia cia.
Kev Nyab Xeeb
Quercetin hmoov yog qhov muaj peev xwm hloov cov tshuaj mutagenic tab sis qhov no tsis txhais tau tias nws yog carcinogenic. Ntau yam hauv vivo kev tshawb fawb ntseeg tias quercetin tsis yog cov kabmob carcinogenic.
