Alocasia macrorrhiza also known as giant taro is a large herbaceous plant belonging to the family Araceae. In this study, the leaves were evaluated for pharmacognostic study and physicochemical parameters. The phytochemical screening was determined to know the phytoconstituents present in the plant. The methanolic extract of the leaves was investigated for quantification of total phenolic and total flavonoid content. The total phenol and flavonoid content was found to be 360mg GAE/g and 80mg QE/g. An in-vitro antioxidant activity has been determined by using DPPH radical scavenging activity, reducing power and nitric oxide assay. The plant extract showed a potential result in inhibiting the free radical scavenging activity. This may be due to the significant amount of phenol and flavonoid content in the plant which may act as a vital source for the treatment of various human ailments.
