Abstract: The present work has been conducted to evaluate the phytochemical screening and antioxidant activity of the methanolic leaf extract of Leucas aspera. The phytochemical screening result showed that the carbohydrate, protein, flavonoids, phenolic flavonoids, saponins and tannins were present in the plant sample. The antioxidant activity of leaf extract was tested by Phosphomolybdenum assay, reducing power activity, nitric oxide scavenging activity and hydrogen peroxide assay. The result suggested that the methanolic leaf extract of Leucas aspera could be a potential source for antioxidant activity and it increased with the increasing concentration. Hydrogen peroxide activity of methanolic leaf extract of Leucas aspera was 98.3%. The present observation suggested that the methanolic leaf extract of Leucas aspera has potent antioxidant activity in a dose dependent manner.
