Purification of extracts from Prangos haussknechtii Bioss afforded prenylated coumarins 1 and 2, monoterpenoid 3, amino acid derivative 4, and seven known compounds. Spectroscopic methods permitted establishment of the structures and relative configuration of these compounds. The pure isolates were tested for antioxidant and anti-inflammatory activities using lipid peroxidation (LPO), 3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyltetrazolium bromide (MTT), and cyclooxygenase (COX-1 and -2) enzyme inhibitory assays. Compounds 1-4 inhibited LPO with IC50 values between 43 and 114 mu M and reduced MTT to formazan blue between 48 and 128 mu M. In anti-inflammatory assays using cyclooxygenase enzymes, COX-1 and -2, these compounds showed inhibition, with IC50 values ranging from 34 to 56 mu M.
