Quercetin CAS 117-39-5 yog dab tsi?

Quercetin daj koob zoo li crystalline hmoov. Rau thermal stability, qhov decomposition kub yog 314 ℃. tuaj yeem txhim kho lub teeb tsis kam ntawm pigments hauv cov zaub mov thiab tiv thaiv kev hloov pauv ntawm cov khoom noj aroma. Nws yuav hloov xim thaum ntsib hlau ions. Me ntsis soluble hauv dej, yooj yim soluble hauv alkaline aqueous daws. Quercetin thiab nws cov derivatives yog flavonoids dav nyob rau hauv ntau yam zaub thiab txiv hmab txiv ntoo.

Daim ntawv thov

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