Foliage
Sesbania bispinosa foliage contains canavanine, a non-protein amino-acid that is an antinutritional factor for livestock (Bell et al., 1978). The content of condensed tannins in the leaves was reported to be low (less than 4 g/kg DM) up to 90 days (bloom stage). It markedly increased to almost 40 g/kg DM. The condensed tannins content in the stems were less than 6 g/kg DM (Al-Masri et al., 2008).
Seeds
Like other legume seeds, Sesbania bispinosa seeds contain phenols, tannins, phytic acid, saponins and trypsin inhibitors as well as high proportions of non-starch polysaccharides such as b-glucans, arabinoxylans, and galactomannan (Hossain et al., 2002a). However, these antinutritional factors are present in low levels n Sesbania bispinosa seeds (Pugalenthi et al., 2004).
