Abstract

Oenanthe javanica Blume (DC) is an aromatic medicinal herb having pharmacological properties such as antioxidant, anti-quorum sensing, anti-coagulant, antitoxic, hepatoprotective, anti-hepatitis B virus and memory improvement. It is one of the most consumed vegetable throughout the year in Manipur. The present study was carried out to analyze the phytochemical constituents, antioxidant activity and total phenolic and total flavonoid content of Oenanthe javanica. Preliminary phytochemical analysis was done using standard procedure. Total phenolic, total flavonoid content and antioxidant activities were determined spectrophotometrically in crude aqueous and methanolic extracts. Preliminary phytochemical analysis indicates the presence of amino acids, carbohydrates, proteins, flavonoids, phenolic compounds, steroids and terpenoids, saponins, tannins, cardiac glycosides except alkaloids and phlobatannins. The present study demonstrates the antioxidant activity of Oenanthe javanica Blume (DC) due to the various phytochemicals present in the extract which confer their traditional uses as food and medicine.
