| Tectorigenin, a Phytoalexin of Centrosema haitiense and Other Centrosema Species  | | | | Abstract
| A phytoalexin isolated from the fungus-inoculated leaflets of Centrosema haitiense, C. pubescens (3 accessions) and C. virginianum has been identified as 5,7,4'-trihydroxy-6-methoxy-isoflavone (tectorigenin). This compound is variously accompanied by other isoflavones includ ing the previously described phytoalexin, cajanin (5,2',4'-trihydroxy-7-methoxyisoflavone). Sub stantial quantities of aesculetin were obtained when C. haitiense leaves were submerged for 48 h in water or fungal spore suspensions. The taxonomic position of Centrosema within the legume tribe Phaseoleae is discussed. | | | |
