摘要：

(-)-6aR,11aR-Dihydro-3-hydroxy-9,10-dimethoxy-6H-benzofuro[3,2c] [1]-benzopyran (10-methoxymedicarpin), (+)-(2,3,4,-trimethoxyphenyl)-2,3-dihydro-7-hydroxy-4H-1-benzopyran (7-hydroxy-2',3',4'-trimethoxyisoflavan) and (+)-(2,3,4-trimethoxy-5-hydroxyphenyl)-2,3-dihydro-7-hydroxy-4H-1-Benzopyran (7,5'-dihydroxy-2',3',4'-trimethoxyisoflavan) were isolated for the first time from dried Medicago sativa hay. Structural assignments were based on H-1 NMR and mass spectra, X-ray crystallography, and optical rotations.
