Objective: This research is to investigate the phytochemical screening, antimicrobial and antioxidant activity of ethanolic leaf, stem and root tubers extracts of Alocasia sanderiana W.Bull. Methods: Antimicrobial activity of ethanolic extracts of leaf, stem and root tubers of Alocasia sanderiana W.Bull was evaluated using agar well diffusion method against bacterial and fungal strains. Gentamicin 10μg/mL and Ketoconazole 10μg/mL were used as standards for antibacterial and antifungal assay respectively. Phytochemical screenings were done using standard methods. Antioxidant activity of ethanolic extracts of leaf, stem and root tubers of Alocasia sanderiana was evaluated by free radical scavenging activity on DPPH●, ABTS●+. The reducing power assay was evaluated against standard ascorbic acid. Results: In the phytochemical study leaf, stem and roots tubers of plant parts were compared. The values show that leaf is more potential other then the stem and root. Leaf, stem and root extract showed significant in vitro antibacterial and antifungal activities. Antioxidant activity on comparing the phytochemical properties shows more potential other then the stem and root. Ethanolic extracts of leaf, stem and root tubers of Alocasia sanderiana showed significant in vitro antioxidant activity. Conclusion: In phytochemical study, leaf shows more potential values compared to stem and root tubers. In antibacterial study, stem shows more inhibition than leaf and root. In antifungal study, stem and root show more inhibition than leaf. Antioxidant activity studies of leaf shows more potential compared to stem and root tubers of A.Sanderiana due to presence of various phytoconstituents and it could be a source of new compounds. Keywords: Phytochemical study, antimicrobial activity, Araceae, Antioxidant activity.
