The present work was intended to establish an efficient and reproducible direct regeneration protocol in Colocasia esculenta and to compare the levels of total phenolics and free radical scavenging activity in in vitro regenerated and wild type plants. In vitro micropropogation protocol of the C. esculenta plant was optimized using meristem as explant. The surface sterilized explants were inoculated on MS supplemented with varied concentration and combination of auxin and cytokinins. The cultures were maintained at 26
