Following, the stomach sample were subjected for the determination of gastric ulcer area (mm2) using the image J software. The length and width of the ulcer was measured using a ruler to assess the total ulcer area. The following formula was used to obtain the percentage of ulcer inhibition (%) by the treatment and the obtained ulcer index was expressed as mean score value for each rat:

Percentage inhibition (%) = [Ulcerated area (model) – Ulcerated area (treated)] / Ulcerated area (model) × 100%
