Abstract : Roots of Lomatium macrocarpum (Hook. and Arn.)C. and R. yielded osthol(7-methoxy-8-(3-methyl-2-butenyl)-coumarin) and a chromone, 2-methyl-5-hydroxy-6(3-methyl-2-butenyl)-7-methoxychromone, identified spectroscopically and by synthesis. The serial parts of the plant also contained this chromone along with sibiricin (5,7-dimethoxy-8-(3-methyl-2,3-epoxybutyl)-coumarin) and a new coumarin named macrocarpin. By spectroscopy and chemical degradation macrocarpin was shown to be 7-methoxy-8-(3-methyl-4-(2-methyl-cis-2-butenoyloxy)-cis-2-butenyl)coumarin. These products were not found in four other Lomatium species examined. (Author)
