Heterocyclic neoflavonoids of the formula (I) are proposed in the e OH or both E together represent oxygen, R 1 represents a 5 or 6-membered heteroaromatic radical which may optionally be substituted and contains at least one or more heteroatoms selected from the group consisting of N, O and S, R 2 in each case hydrogen or OR b , where R b is hydrogen, C 1 -C 5 -alkyl or C 2 -C 5 -alkenyl and, if appropriate, two immediately adjacent radicals R 2 together may form a group OCH 2 O, or their physiologically acceptable salts. |
