Several secondary metabolites, artemetin (1), casticin (2), 3,3′‐dihydroxy‐5,6,7,4′‐tetramethoxy flavon (3), penduletin (4), methyl 4‐hydroxybenzoate (5), p ‐hydroxybenzoic acid (6), methyl 3,4‐dihydroxybenzoate (7), 5‐hydroxy‐2‐methoxybenzoic acid (8), vanillic acid (9) and 3,4‐dihydroxybenzoic acid (10) were isolated from a folkloric medicinal plant, Vitex agnus‐castus . The structures of compounds 1–10 were identified with the help of spectroscopic techniques. Compounds 3–10 were isolated for the first time from this plant. These compounds were screened for their antiinflammatory and lipoxygenase inhibitory activities. Compounds 6, 7 and 10 were found to have significant antiinflammatory activity in a cell‐based contemporary assay, whereas compounds 1 and 2 exhibited a potent lipoxygenase inhibition.
