Phytochemical screening and Anti-oxidant activity of Ammannia octandra L.f
The investigation includes phytochemical screening of different extracts of Ammannia octandra L.f. Petroleum ether, Chloroform, Ethyl acetate, Ethanol as well as the aqueous extracts of Ammannia octandra L.f showed many phytoconstituents. The phytoconstituents of Ammannia octandra L.f were found to be glycosides, alkaloids, flavanoids, tannins and phenolic compounds. Antioxidant activity was determined for three extracts (Petroleum ether, ethyl acetate and ethanolic). DPPH assay, Superoxide free radical scavenging activity, Nitric oxide radical scavenging activity, Hydroxyl radical scavenging activity as well as Total antioxidant activity methods were followed for antioxidant assays. The ethanolic extract showed better antioxidant activity. Pharmacological screening of different therapeutic activities of Ammannia octandra L.f has to be carried out so that it may be used in future as a good natural antioxidant source.
