The ethanol leaf extract (ELE) of Cassia fistula Linn. (Caesalpinaceae) was evaluated for antiulcer activity against pylorus ligation-induced gastric ulcer. Ranitidine (30 mg/kg b.w.) and ELE at doses of 250, 500, and 750 mg/kg b.w. were administered orally in different groups of rats (n = 6), 1 h prior to pyloric ligation. Four hours after pyloric ligation, the gastric juice was collected for evaluation of various parameters. The antiulcer activity of ELE was evidenced by the significant attenuation of gastric volume, pH, free acidity, and total acidity in the gastric juice of pyloric-ligated rats in a dose-dependent manner, and this protective effect could be due to strengthening of the mucosal defense mechanism. ELE pre-treatment significantly attenuated the fall in status of sialic acid and fucose accompanied by an increase in hexose, hexosamine, total non-amino polysaccharide, total carbohydrate, and C:P ratio in the gastric juice of pylorus-ligated rats, and this effect could be due to protection of the mucosal barrier system. ELE pre-treatment significantly prevented the increase in LPO and SOD accompanied by a fall in CAT, in the gastric juice of pyloric-ligated rats. This protective ability of ELE against pylorus ligation-induced gastric ulcer could be attributed to its free radical scavenging and antioxidant properties. Higher doses of ELE (750 mg/kg b.w.) produced maximum antiulcer activity comparable to ranitidine treatment. In essence, the antiulcer activity of ELE could be attributed to (i) a decrease in gastric acid secretion, (ii) protection of the mucosal barrier and restoration of mucosal secretions, (iii) inhibition of free radical generation or prevention of lipid peroxidation, and (iv) free radical scavenging or antioxidant properties.

Aegle marmelos Linn is a common plant used to treat many disease Conditions in Indian traditional systems of medicine. The present study was undertaken to findout a scientific validation for the efficacy of Aegle marmelos against gastric ulcer. Aqueous extract of Aegle marmelos leaves was prepared and used for investigation. A daily does of 1 gm/kg body weight of the extract administered orally for 21 days. The volume of the gastricse cretion, ulcer lesion count, pepsin content, PH, total acidity, hexose and hexosamine content were estimated. The result indicated a significant reduction in the ulcer lesion count, volume of gastric juice and acidity and increase in pH and hexosamine after treatment with extract. However the pepsin and hexose content not significantly altered. Histopathological studies were conducted to support the antiulcer study.
