Plants contain several compounds among which are phytochemicals with both beneficial (medicinal, nutritional, antibiotic and environmental) and deleterious (bitter taste, poisonous, chelate) effects on organisms consuming them. Eighteen (18) tropical plants comprising 8 herbaceous plants, 4 trees and 5 shrubs and ornamentals were assayed for their antinutritional factors using qualitative and quantitative techniques. Saponin, tannin, steroid, triterpeniod, cardiac glycoside and phlobatanins were present in all tropical plants examined. Alkaloids used in preparing poison was absent in all samples that were assayed, there were varying quantities of antinutritional factors in all. Saponin content in the plants ranged from (6.22-19.53 g/100 gDM) Adanzonia digitata and Vernonia amygdalina respectively this can be exploited for its nutritional and medicinal benefits for human, animal and environment. Enhancement of protein in form of by-pass protein can be achieved by exploiting tannin which ranged from Morinda lucida (0.53 g/100 gDM) to Talinum triangulae (2.80 g/100 gDM), flavonoids ranged from Newbouldia laevis (0.89 g/100 gDM) to Physalis angulata (10.52 g/100 gDM). Moreover, Phenol is important for its antiseptic action ranged from (0.60 g/100 gDM) in Corchorus olitorium and Morinda lucida to in Talinum triangulae (3.18 g/100 gDM) (p |
