ISOLATION, CHARACTERIZATION AND EVALUATION OF ANTI-ULCER ACTIVITY OF PHYTOCONSTITUENTS PRESENT IN MORINGA OLEIFERA LEAF

Moringa oleifera leaf is widely used in the traditional medicine system and also used as a food by different communities and local tribes of Assam in India. Moringa oleifera leaf contains various bioactive compounds such as alkaloids, flavonoids, rutin, steroids, etc. The flavonoids quercetin act as an anti-ulcer agent, and rutin have a gastro cytoprotective effect i.e., present in M. oleifera leaf. The main aims of the current study were to isolate and characterize the active compounds using column chromatography and spectroscopy, respectively, and evaluate the anti-ulcer activity of Moringa oleifera leaf extract. The FTIR analysis of isolated compounds indicated the presence of functional groups OH, C=C, C-Cl, C-Br. Besides these, the FTIR spectroscopy for ethanolic leaf extract confirmed the presence of COOH, O-H, N-H. The results of the IR analysis also reveal that the components of Moringa oleifera leaf could be aromatic or aliphatic alcohols or phenols, amine, ketones, esters, and some nitrogen-containing compounds. In in-vitro anti-ulcer screening, the ethanolic extract of Moringa oleifera possessed an antacid, antisecretory, anti-ulcer property which might be due to the presence of saponin. The current study results suggest that consumption of the leaves of Moringa oleifera may be beneficial in the healing of ulcers in patients suffering from peptic ulcer disease.
