Three further minor isoflavonoid components (1-3) of the dichloromethane extract of Desmodium canum root have been isolated: two of them are complex isoflavanones with structures 1 and 2 biogenetically related to the previously isolated compounds 1a and 2a. The third is a complex isoflavan where the isoprenyl substituent and the aromatic A-ring yielded a p-quinol nucleus.
