Article abstract of DOI:10.1016/0031-9422(81)85177-1

Isoformononetin, glyceollins I, II and III, and 2-isopentenyl-3,6α,9-trihydroxypterocarpan (glyceocarpin) accumulated in soybean (Glycine max) leaves after treatment with aqueous sodium iodoacetate or a cell suspension of the bacterium, Pseudomonas pisi.These compounds were also accompanied by two previously unreported pterocarpans, glycerofuran and its 9-O-methyl derivative.Glyceocarpin is described for the first time as a plant product.Key Word Index- Glycine max; Leguminosae; soybean; Pseudomonas pisi; isoflavonoids; pterocarpans; isoflavone; phytoalexins; antibacterial activity.
