摘要: Two new isoflavonoids were isolated from red clover as germination inhibitors for the same plant and their structures determined a glucoside of biochanin A (7-d-β-glucosyl-5,7-dihydroxy-4′-methoxyisoflavone) (II) its 5-malonate (I), respectively. Besides these compounds following substances also inhibitors: trifolirhizin (III), ononin (IV), daidzein (V) 7-glucoside (VI), formononetin (VII), genistein (VIII) (IX).
