    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 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, named hedysarumine A and hedysarumine B, along with a known isoprenyl chalcone paratocarpin E were isolated from the roots of Hedysarum gmelinii for the first time. Their structures were elucidated based on NMR and MS spectral analyses.
