抄録

From the underground parts of Glehnia littoralis Fr. Schmidt ex Miquel (Umbelliferae), 26 compounds, including two new lignan glycosides [glehlinosides A (1) and B (2)], a new neolignan glycoside [glehlinoside C (3)], and a new phenylpropanoid glycoside [4-[β-d-apiofuranosyl-(1→6)-β-d-glucopyranosyloxy]-3-methoxypropiophenone (4)], were obtained and their structures were determined by analysis of their spectral data. The 1, 1-diphenyl-2-picrylhydrazyl radical-scavenging assay disclosed quercetin (8), isoquercetin (9), rutin (10), chlorogenic acid (11), and caffeic acid (24) as the major antioxidative constituents in this crude drug.
