Xanthosoma plants are widely cultivated in tropics and mostly used as staple food. It can be found in vacant lots, dirt roads and pathways, plantations, and near highways. This research paper was undertaken to study the morphological characteristics and the present secondary metabolites in three distinct parts (stalk, corm and leaves) of five selected Xanthosoma species namely X. sagittifolium Schott, X. violacuem Schott, X. aureum Schott, X. cf robustum, and X. cf monstrousum. Samples were collected within CFCST Campus, Doroluman Arakan, Cotabato. Plant samples were soaked in 80 % ethanol solution and subjected to phytochemical tests of alkaloids, saponins, tannins and flavonoids.


Results revealed that the leaves, stalk and corm of all plant samples except X. sagittifolium corm contain saponins. All plant samples except the leaves of X. cf robustum were positive of flavonoid. Only the stalk of X. cf robustum and leaves of X. aureum is positive of alkaloid and all other plant samples are negative. In addition, all other plant samples are positive of tannin except the leaves and corm of X. cf robustum. Hence, the present study confirms the potential of plant samples to be used as medicinal plant.
