| Popis: | Compared to its leaf, few studies have been reported on the seeds of Moringa oleifera Lam. Metabolites profiling analysis of M. oleifera seed methanolic extract (ME) and its fixed oil (MO) was attempted via LC/MS and GC/MS. LC/MS analysis of M. oleifera seeds annotated 84 peaks of which glucosinolates and their corresponding acetyl isomers were abundant. GC/MS of seed oil revealed the abundance of fatty acids with oleic acid at 34.3%. ME exhibited significant anti-Helicobacter pylori activity with MIC50 0.92 µg/mL, nearly one-half that of Clarithromycin. Fixed oil (MO) showed a nonselective anti-inflammatory effect with IC50= 24.4 ± 0.8 µg/mL correlated to Ibuprofen. To unravel the mechanism of the anti-H. pylori activity a molecular docking study of the principal components of the ME has been performed, using H. pylori urease enzyme. Interactions with Ni2+ ions and amino acid residue in the active site, which are crucial for the enzyme's biochemical role, are evidenced. |
