Moringa leaves
Moringa leaves have been found free of trypsin inhibitors. Saponin content was relatively high (up to 8%). Moringa leaves and twigs contained limited amounts of cyanogenic glucosides (Makkar et al., 1997). The latter study did not detect glucosinolates in the leaves and only trace amounts in leaves and stems, but later trials using a different method of analysis reported significant amounts of glucosinolates (Bennett et al., 2003; Amaglo et al., 2007; Bellostas et al., 2010). Condensed tannins are either absent (Makkar et al., 1997) or present in small amounts (Bakhashwain et al., 2010; Moyo et al., 2011). Ethanol-extracted leaf meals were not reported to contain antinutritional factors (Afuang et al., 2003).
Moringa seed cake
Moringa seeds contain important amounts of glucosinolates (Bennett et al., 2003). Moringa seed cake was also found to contain significant amounts of glucosinolates and phytate (65.5 µmol/g and 4.1% respectively) as well as saponins, but in a lesser concentration (1.4%) than in the vegetative fractions. Some haemagglutination activity was detected in the meal (Makkar et al., 1997).
