Antimicrobial Study of Tephosia Nubica Flavones

Tephrosia press. species (Leguminosae) used medicinally and as fish poison, are known to be a source of flavonoids. The antimicrobial activity of the prenylated flavones, semiglabrin, pseudosemiglabrin, appollinine and lanceolatin A, which we have isolated from Tephrosia nubica herb, widly grown in Egypt, was studied. The results revealed that the four flavanoids exhibit an antifungal activity against Aspergillus niger, Penicillium funiculosum, Fusarium moniliforum and Phoma spp.
