The drumstick tree Moringa oleifera Lam. (Moringaceae), distributed in many parts of the world, is an important food plant with high nutritional value and used in medical applications and pharmaceutical industries. The aim of this study was to highlight the gastroprotective effect of Moringa oleifera in hydrochloric acid/Ethanol (HCl/EtOH) in a rat model.
Moringa phytocompounds were characterized by infrared spectra (FTIR). Rats were induced for gastric ulcer with 150 mmol/L HCl/60% EtOH solution and pretreated orally with the edible infusion extract of the leaves of Moringa oleifera at a single dose of 100 mg/kg body weight (bw). Antioxidant parameters and lipid peroxide levels were measured and the pathological damage was histologically analysed.
The FTIR analysis showed the presence of several chemical biocompounds. The methanolic extract is the potent radical-scavengers with an estimated value of 87.54% at the higher concentration used (500 µg/ml) and antibacterial agent. Further, the DPPH inhibition value of the M. oleifera infusion was 80.58%. For in vivo analysis, mucus was highly produced in gastric mucosa of plant-treated rats, thereby pH were elevated in rats pretreated with M. oleifera compared to ulcerated animals. Whereas, lesion index was markedly reduced (79%) in stomach protected with plant. Interestingly, oral administration of M. oleifera protected gastric mucosa through decreasing MDA levels as well as increasing antioxidant enzyme activities (CAT, SOD, GPx).
Overall, the therapeutic value against acidified ethanol induced gastric and ulcer ability of M. oleifera might be due to its biocompounds.
