Antioxidant Activity, Total Phenolic and Total Flavonoid Content of Oenanthe Javanica Blume (Dc) Collected From Imphal West District

Abstract

Oenanthe javanica Blume (DC) is an aromatic medicinal herb having pharmacological properties such as antioxidant, anti-quorum sensing, anticoagulant, 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.

Phytochemical Profile and Biological Activities of the Extracts from Two Oenanthe Species (O. aquatica and O. silaifolia)

“…As far as we know, no previous research has been done on the tested Oenanthe species. In agreement with our results, Bhaigyabati et al [24] reported that the methanolic extract from O. javanica contained a higher content of phenolics and flavonoids than the aqueous extract. When comparing our results with previous studies on several Oenanthe species, we have also found different results.…”

Phenotypic, Nutritional, and Antioxidant Characterization of Blanched Oenanthe javanica for Preferable Cultivar

“…In China, the steamed stems of water dropwort are used with boiled rice. Frying blanched water dropwort is also common in China (Ma et al, 2010;Chan et al, 2014Chan et al, , 2017Bhaigyabati et al, 2017).…”

Antioxidant Activity of Two Edible Korean Seaweed Oil Obtained from SC-CO2 and Solvent Extraction

“…The ABTS scavenging activity was determined by differential extraction methods. The percentage efficiency of ABTS scavenged by seaweed extract was found to increase with increasing concentration [39]. As shown in Fig.…”

“…DPPH has been used extensively as a stable free radical to evaluate reducing substances and is a useful reagent for investigating free radical scavenging activity of the components [39]. The results are shown in Fig.…”
