11409965-2	2001	From seven structurally divergent groups of flavonoids, only flavonols with a free hydroxyl group at the C-3 position of the flavonoid skeleton showed high inhibitory activity to beta-carotene oxidation.	Flavonols	61-70	complement C3	Homo sapiens	105-108	
31013947-6	2019	The flavonols were more active than the flavones against LDL oxidation, suggesting that hydroxyl group at C-3 and the catechol moiety at B-ring may play important roles in protecting LDL from oxidation.	Flavonols	4-13	complement C3	Homo sapiens	106-109	
7673925-3	1995	Flavones and flavonols exhibited a strong inhibitory effect on trypsin; the presence of hydroxyl groups at positions C-5 and C-7 in ring A is necessary for inhibition of the enzyme, while the simultaneous presence of free hydroxyl groups at positions C-3" and C-4" enhances the inhibitory activity.	Flavonols	13-22	complement C3	Homo sapiens	251-254
