Three new homoisoflavanones from the bulbs of Ledebouria floribunda.

María Isabel Calvo1.   

Abstract

Three new homoisoflavanones, namely ledebourin A (1), ledebourin B (2) and ledebourin C (3) were isolated from the bulbs of Ledebouria floribunda. Their structures were elucidated on the basis of detail spectroscopic analyses. This is the first report of this type of homoisoflavanones. Ledebourin B (2) and ledebourin C (3) exhibited potent antioxidant activity in the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging compared to the positive controls, the well-known antioxidant BHT and BHA.
