Popis: Two new flavonoids, acanthophorin A (1) and acanthophorin B (2), along with three known compounds tiliroside (3), (-)-catechin (4) and quercetin (5) were isolated from the red alga Acanthophora spicifera. The structures of 1 and 2 were determined to be kaempferol 3-O-α-L-fucopyranoside (1) and quercetin 3-O-α-L-fucopyranoside (2) by spectroscopic methods. Both 1 and 2 showed significant antioxidant activity.
