Fruits of Momordica charantia L.-cucurbitaceae have been frequently used in folk medicine for rapid healing of cutaneous lesions and peptic ulcer, especially in Western Anatolia in Turkey.


The anti-ulcerogenic effect of the oily extract of Momordica charantia fruits was investigated in male Sprague-Dawley rats. Animals were separated into six groups. Distilled water (control group), famotidine (40 mg/kg), oily extracts (5 and 10 ml/kg), and vehicles (olive oil -5 and 10 ml/kg) were given orally (gavage). Thirty minutes later indomethacin (25 mg/kg) was administrated to all the groups. Six hours later, animals were killed with decapitation. For each stomach, ulcerated and total areas were measured (mm2). The ulcer indexes for each stomach and the ulcer inhibition rates for each group were calculated, after which the stomachs were evaluated pathologically (polymorphonuclear leukocytes infiltration).


Ulcer inhibition rates were as follows: famotidine -91.54%, oily extract (5 ml/kg) -53.80%, oily extract (10 ml/kg) -98.04%, vehicle (olive oil -5 ml/kg) -18.40%, and vehicle (olive oil -10 ml/kg) -88.02%. According to polymorphonuclear leukocytes infiltration, oily extract (10 ml/kg) and vehicle (10 ml/kg) had similar effects to famotidine.


The olive oil extract of M. charantia fruit did show a protective effect macroscopically.
