Gastroduodenal ulcer protective activity of Asparagus racemosus: an experimental, biochemical and histological study.
Asparagus racemosus is an Ayurvedic rasayana, which finds mention in ancient Indian texts for treatment of gastric ulcers. The ulcer protective effect of methanolic extract of fresh roots of A. racemosus (ARM), 25-100 mg/kg given orally, twice daily for 5 days, was studied on different gastroduodenal ulcer models. ARM 50 mg/kg, twice daily, orally (total saponins 0.9%) showed significant protection against acute gastric ulcers induced by cold restraint stress (CRS), pyloric ligation, aspirin plus pyloric ligation, and duodenal ulcers induced by cysteamine. ARM in the above dose also significantly healed chronic gastric ulcers induced by acetic acid after 10 days treatment. However, ARM was ineffective against aspirin- and ethanol-induced gastric ulcers. Further, gastric juice and mucosal studies showed that ARM significantly increased the mucosal defensive factors like mucus secretion, cellular mucus, life span of cells and also possessed significant anti-oxidant effect, but had little or no effect on offensive factors like acid and pepsin.
