• Three new chromones (8,9,and 12), named 3'-O-angeloylhamaudol, ledebouriellol, and 4'-O-β-D-glucosyl-5-O-methylvisamminol, respectively, were isolated from the root and rhizoma of Ledebouriella seseloides WOLFF (Umbelliferae), together with five known coumarins (1-5) and six known chromones (6,7,10,11,13 and 14). The structures of 8,9,and 12 were elucidated as (3S)-3,4-dihydro-5-hydroxy-3-(2-methyl-2-butenyl) oxy-2,2,8-trimethyl-2H, 6H-benzo [1,2-b : 5,4-b'] dipyran-6-one, (3S)-3,4-dihydro-2,2-dimethyl-5-hydroxy-8-hydroxymethyl-3-(2-methyl-2-butenyl) oxy-2H, 6H-benzo [1,2-b : 5,4-b'] dipyran-6-one, and (2S)-2,3-dihydro-2-(1-β-D-glucopyranosyloxy-1-methylethyl)-4-methoxy-7-methyl-5H-furo [3,2-g] [1] benzopyran-5-one, respectively, by chemical and spectral studies.
