Background: To evaluate the antiulcer activity of ethanolic leaves extract of Saraca indica against ethanol, pylorus ligature and indomethacin in albino rats. Materials and Methods: Ulcer was produced by ethanol, pylorus ligature and indomethacin in albino rats. Five groups (n=6) of rats were orally pre-treated with carboxymethyl cellulose solution, and ranitidine (80 mg/kg) respectively. In ethanol induced ulcer, the animals were treated with 200 and 400 mg/kg b.w. ethanolic leave extracts of Saraca indica in 0.3% CMC solution, 60 minutes before oral administration of absolute ethanol to produce gastric mucosal injury. In indomethacin induced ulcer, the drug was administered orally at the dose of 30 mg/kg b.w. After 7-9 hours of administration of indomethacin (30 mg/kg); the animals were sacrificed with high doses of anesthesia. In the pylorus ligature method, volume of free acidity, gastric secretion, pH and total acidity were estimated. In all three models, the ulcer index and % protection were estimated. Results: The anti ulcer activity of ethanolic leave extracts of Saraca indica in ethanol, indomethacin and pylorus ligature models is evident from the significant (P<0.001) reduction in ulcer index. In pylorus ligature model, significant (P<0.001) reduction in total acidity gastric volume and increase in pH were observed when compared with the standard drug. Conclusion: Ethanolic leave extracts of Saraca indica were found to be significantly protective against ethanol, indomethacin and pylorus ligature induced gastric ulcers in the experimental albino rats. The result obtained suggest that ethanolic leave extracts of Saraca indica possesses significant anti-ulcer activity.

Background: Gastric ulcer is one of the most prevalent gastrointestinal disorders, which affects approximately 5-10% of people during their life. In recent years, abundant work has been carried out on herbal medicine to clarify their potential efficacy in gastric ulcer prevention or management. The present study was carried out to evaluate the antiulcer activity of the methanolic root extract of Berberis lycium in albino rats. Method: The methanolic root extract of Berberis lycium was prepared by hot extraction method. Anti-ulcer activity was evaluated and method employed was pylorus ligation and ethanol induced in albino rats. Preliminary methanolic extract of Berberis lycium was subjected to the acute oral toxicity study according to the OECD guideline no. 425. Animals were divided into four groups of six animals each. The animals of Group I served as normal control (vehicle) which received distilled water. Group II and III received 250 mg/kg and 500 mg/kg of methanolic root extract, respectively. In pylorus ligation induced ulcer model, various parameters were studied viz. gastric volume, pH, total acidity, free acidity, and ulcer index. Ulcer index and percentage inhibition of ulceration was determined for ethanol induced ulcer model. Group IV received Ranitidine at 50 mg/kg was used as the standard drug. Pretreatment of methanol root extract of Berberis lycium showed significant (P˂0.05) decrease in the gastric volume, total acidity and free acidity. However, pH of the gastric juice was significantly increased only at higher dose 500 mg/kg. It showed also significant (P˂0.05) decrease in number of ulcers and ulcer score index in pylorus ligation and ethanol induced ulceration models. Results: The methanol root extract of Berberis lycium showed a significant reduction in the total acidity, free acidity and acid volume. The efficacy of plant extract at high dose was comparable with the standard drug Ranitidine. Conclusion: Our study results support the ethnomedical use of root of Berberis lycium. Keywords: Antiulcer activity, Berberis lycium, Pylorus ligation, Ranitidine, Ulcer Index.

Channa striata (Bloch.) is a fresh water fish belonging to the family Channidae. The stripped snakehead fish possesses wide range of medicinal properties. In view of traditional use of C. striata for wound healing, the present study was undertaken to investigate the beneficial effects of orally administered freeze dried aqueous extract of Channa striata (AECS) in experimentally induced gastric ulcers in Wistar rats. Aspirin induced ulcerogenesis in pyloric ligation model was used for the assessment of antiulcer activity and Ranitidine (50 mg/kg) was employed as the standard drug. The various gastric parameters like volume of gastric juice, pH, free and total acidities, ulcer index, and levels of antioxidant enzymes like catalase, superoxide dismutase, and lipid peroxidation marker malondialdehyde were determined. AECS at concentrations of 40% and 50% w/v significantly decreased the volume of gastric juice and increased the levels of catalase while considerable decrease in free and total acidities and increase in superoxide dismutase were observed with the treatment of standard drug and AECS (50% w/v). All the test doses of AECS markedly decreased ulcer index and malondialdehyde compared to the standard drug whereas AECS 30% w/v did not alter volume of gastric juice, pH, free and total acidities, catalase, and superoxide dismutase. From these findings, it can be concluded that AECS is devoid of acid neutralizing effects at lower doses and possesses antisecretory and antiulcer activities and this could be related to its antioxidant mechanism.

Adansonia digitata (AD) Linn has been used to cure PU in Ayurveda but its efficacy has not been validated. The current study was so carried out to evaluate the antiulcer activity of ethanolic extract of Adansonia digitata fruit pulp (ADFP), n hexane extract of Adansonia digitata seed oil (ADSO) and their combination (ADFP+ADSO) in rats. The effect of AD on gastric ulcer in pylorus ligation induced and ethanol induced models was studied using doses [ADFO (500 mg/kg), ADSO (300 mg/kg) and combination of ADFP and ADSO] for 10 days. Omeprazole (10 mg/kg) were used as the standard drug. Depending on the model, outcomes measures were gastric volume, pH, free acidity, total acidity, ulcer index, percentage inhibition of ulcer index, protein, pepsin, mucus, antioxidant marker enzyme level (Superoxide dismutase, Catalase, Lipid peroxidation), morphological and Histopathological study. The result obtained with combination was set up near to the standard drug and consequence showed that the combination of ADFP and ADSO was found to be more effective than the individual extract of AD. The outcomes were statistically evaluated with the one-way ANOVA followed by the test of Dennett’s‘t’. The secondary-metabolites such as flavonoids, proteins, saponins, tannins, phenols, terpenoids, alkaloids and Fatty acids (palmitic acid, oleic acid, linoleic acid) are potent as antioxidant, antiulcer and anti-inflammatory. The finding of this reading confirmed that AD has antiulcer activity due to 1 or more of the secondary-metabolites present in it. Therefore, this study validates its antiulcer use in Ayurveda. Future investigation on separation of specific phytochemicals and elucidate MOA are needed.

Peptic ulcer is a condition which results from an imbalance between offensive and defensive factors of gastrointestinal system. The investigation was designed to evaluate the antiulcer activity of Symplocos racemosa whole plant methanol extract (MESR) in rat model of indomethacininduced gastric ulceration. The total acidity, gastric volume, pH and free acidity were measured to determine the anti-ulcer activity of MESR. Pretreatment with MESR (125-500 mg/kg) markedly reduced the indomethacin-induced increase in gastric ulcer index and score. These results revealed that antisecretory effects MESR were responsible for antiulcer activity of MESR.
