Antiulcer potential of the ethanolic extract of Aerva persica Merrill root in rats.
ABSTRACT The ethanol extract of the roots of Aerva persica (Burm f) Merrill (Amaranthaceae) was investigated to determine its antiulcer and in vivo antioxidant activities in albino Wistar rats. Ulcers were induced by ethanol and pylorus ligation. The extract was administered at the dose of 200mg/kg orally, p.o. for 15 consecutive days. The ulcer index of the ethanol extract was found to be significantly reduced compared with control animals. The effect was also assessed by determining the free acidity, pepsin activity, total carbohydrate (TC), and protein content (PK) in control, standard, and test group animals. The in vivo antioxidant activity was evaluated by determining the reduced glutathione level (GSH) and malondialdehyde (MDA) level in the tissue homogenates. The results reveal the significant reduction in the level of malondialdehyde and the increase in the level of reduced glutathione in the rats that received the ethanolic extract. Furthermore, histopathological studies have shown that pretreatment with the ethanolic extract of the roots of A persica reduces (100%) ethanol- and pylorus ligation-induced hemorrhagic necrosis in rats.

ABSTRACT: In the Indian traditional system of medicine is commonly used to treat various ailments including peptic ulcer, inflammation, and pain. Ulcer preventive and ulcer protective activities of HAOP and MOP stem bark extracts of (100 mg/kg, b.w., orally) were evaluated employing aspirin + pylorus ligation (APL) model in experimental rats. The results suggested that both extracts (HAOP and MOP) possess enhanced ulcer preventive and protective activities when compared with the standard drug ranitidine. HAOP showed more pronounced effect when compared to MOP. Further the result of the histopathological and biochemical studies also confirms potent ulcer preventive and protective nature of a extracts in a similar manner.Evidence-based Complementary and Alternative Medicine 01/2013; 2013:272134. · 1.72 Impact Factor

ABSTRACT: In the present study, an ethanolic root-bark extract of Moringa oleifera (MO) was examined for its antiulcer potential in albino Wistar rats using two experimental models: ethanol-induced and pylorus ligation-induced gastric ulceration. The extract was orally administered at three different doses (150, 350, and 500 mg/kg) for 15 consecutive days. The antiulcer effects in rats treated with different doses of the extract and omeprazole (30 mg/kg, p.o.) were determined and compared statistically with the antiulcer effects in the control rats treated with saline (NaCl, 0.9%). The MO at doses of 350 and 500 mg/kg decreased the ulcer index significantly as compared to the control group (p < 0.01). The percentage protections against gastric ulcers were 82.58%, 85.13%, and 86.15% for MO doses of 150, 350, and 500 mg/kg, respectively, in the pylorus-ligated ulcer model and 55.75%, 59.33%, and 78.51%, respectively, in the ethanol-induced ulcer model. The MO significantly reduced the free acidity, total acidity, and ulcer index (p < 0.01) and increased the pH of gastric content compared with the control group. This study suggests that MO possesses valuable antiulcer, antisecretory, and cytoprotective activity. Thus, an ethanolic root-bark extract of Moringa oleifera can be used as source for an antiulcer drug.Journal of acupuncture and meridian studies. 08/2013; 6(4):214-20.
