Abstract: | Two new isoprenyl chalcones, 1-2,4-dihydroxy-3-(2-hydroxy-3-methyl-3-butenyl)phenyl]-3-(2,2-dimethyl-2H-benzopyran-6-yl)-2-propen-1-one (1) and 1-4-hydroxy-2-(1-hydroxy-1-methyl-ethyl)-2,3-dihydro-benzofuran-5-yl]-3-3-(3-methyl-2-butenyl)-4-hydroxy-phenyl]-2-propen-1-one (2), named hedysarumine A and hedysarumine B, along with a known isoprenyl chalcone paratocarpin E (3) were isolated from the roots of Hedysarum gmelinii for the first time. Their structures were elucidated based on NMR and MS spectral analyses. |
