Iyini i-Quercetin CAS 117-39-5?

Inaliti ephuzi emise okwe-crystalline powder. Ngokuzinza kwe-thermal, izinga lokushisa lokubola lingu-314 ℃. Ingathuthukisa ukumelana nokukhanya kwezingulube ekudleni futhi ivimbele izinguquko ephunga elimnandi lokudla. Izoshintsha umbala lapho ihlangana nama-ion ensimbi. Incibilika kancane emanzini, incibilika kalula ezixazululweni ezinamanzi ane-alkali. I-Quercetin kanye nokuphuma kwayo kukhona ama-flavonoid atholakala kabanzi emifino nasezithelo ezihlukahlukene.

Isicelo

I-Quercetin, njengenhlanganisela evame kakhulu ye-flavonoid, inemisebenzi ehlukahlukene yezinto eziphilayo futhi ingamelana ne-oxidation, idlala indima ebalulekile ekwelapheni komtholampilo komdlavuza kanye nezifo zenhliziyo. I-Quercetin ayihlanganyeli kuphela ekusebenzeni kwe-in vitro antioxidant futhi ingavimbela ukulimala kwe-DNA oxidative, kodwa futhi ivikela izicubu emonakalweni we-oxidative ngokunciphisa ukuhlushwa kwe-peroxide ku-vivo.
