Cyclooxygenase inhibitory and antioxidant bioassay-directed extraction and purification of celery seeds yielded sedanolide (1), senkyunolide-N (2), senkyunolide-J (3), 3-hydroxymethyl-6-methoxy-2,3-dihydro-1H-indol-2-ol (4), L-tryptophan (6), and 7-[3-(3,4-dihydroxy-4-hydroxymethyl-tetrahydro-furan-2-yloxy)-4,5-dihydroxy-6-hydroxymethyl-tetrahydro-pyran-2-yloxy]-5-hydroxy-2-(4-hydroxy-3-methoxy-phenyl)-chromen-4-one (7). The structures of compounds 1-7 were determined using spectroscopic methods. Compound 4 is reported here for the first time. At 250 mug ml(-1), compounds 1-4, 6 and 7 displayed prostaglandin H endoperoxide synthase-I (COX-I) and prostaglandin H endoperoxide synthase-II (COX-II) inhibitory activities at pH 7. The acetylated product (5) of compound 4 also inhibited COX-I and COX-II enzymes when tested at 250 mug ml(-1). Compounds 6 and 7 exhibited good antioxidant activity at concentrations of 125 and 250 mug ml(-1). Only compounds 1-3 exhibited topoisomerase-I and -II enzyme inhibitory activity at concentrations of 100, 200 and 200 mug ml(-1), respectively.
