摘要：

Bioassay-directed fractionation of Desmodium canum resulted in the isolation and characterization of three antimicrobial isoflavanones. These compounds, namely, desmodianones A, B and C, were assigned the structures 5,7,2'-trihydroxy-6,6''-dimethyl-6''-(4-methylpent-3-enyl)pyrano(2'',3'':4',5')isoflavanone, 5,2'4'-trihydroxy-7-methoxy-6-methyl-8-(3-methylbut-2-enyl)-isoflavanone, and 5,7,2',4'-tetrahydroxy-6-methyl-5'-(3,7-dimethylocta-2,6-dienyl)-isoflavanone, respectively.
