Nacedero foliage is free from alkaloids and condensed tannins, with low contents in saponins and steroids. Phenol content was extremely variable, from 0.045 to 5% of DM, which has been suggested to be the cause of the large variations of nutritional value observed in feeding trials with Trichanthera gigantea. The tannins from nacedero may be of the hydrolysable type (Rosales, 1997). In Venezuela, in a comparison of 11 other forage tree species, nacedero had no detectable concentrations of coumarins, saponins, or bitter compounds, low concentrations of alkaloids and moderate contentrations of terpenes (Garcia et al., 2008).
