Određivanje antioksidativne aktivnosti flavonoida DPPH metodom

2007
Ispitan je antioksidativni učinak flavonoida različite kemijske strukture. Primjenom DPPH metode testirana je i uspoređena antiradikalska sposobnost kvercetina, miricetina, apigenina i naringenina. Flavonoli kvercetin i miricetin pokazali su znatnu sposobnost hvatanja DPPH-radikala (IC50 = 1, 22 μ g/mL i 2, 5 μ g/mL), dok naringenin i ...

Kinetika reakcija kvercetina i DPPH radikala

2022
Kvercetin spada u podskupinu flavonola te mu se pripisuje niz bioloških učinaka: antioksidativni, antikarcinogeni, antialergijski, protuupalni i drugi. Reakcije flavonoida i DPPH• uobičajeno se prate tako što se mjeri smanjenje apsorbancije na valnoj duljini koja odgovara maksimumu DPPH•.

[Screening DPPH radical scavengers from Monascus sp].

Wei sheng wu xue bao = Acta microbiologica Sinica, 2004
A strain belongs to Monascus sp. was separated from hongqu(Chinese beni-coji) which was used to brew red wine in Changxin county, Zhejiang province, and its DPPH radical scavenging metabolites were studied. Results showed that the yield and radical scavenging activity of neutral extract with EtOAc were higher than that of acid and basic extract.
