3',4'-Dihydroxyflavonol (DiOHF) 是一种有效的抗氧化剂，可降低糖尿病大鼠肠系膜动脉中的超氧化物并改善 NO 功能。
3',4'-Dihydroxyflavonol (DiOHF) acutely preserves nitric oxide (NO) activity in the presence of elevated reactive oxygen species (ROS). DiOHF improves NO activity in diabetes by reducing Nox2-dependent superoxide production and preventing eNOS uncoupling to improve endothelial function.
