title: Gastric cytoprotection of bolivian medicinal plants.
abstract: Several extracts obtained from Bolivian medicinal plants have been evaluated for cytoprotective activity on ethanol-induced ulcer formation in rats. Preliminary results suggest, that the majority of the plants tested showed a significant activity, the aqueous extracts of Phoradendron crassifolium and Franseria artemisioides being the most active, exerting a cytoprotective activity comparable to atropine. The analysis of the chemical constituents of the extracts studied showed the presence of tanins, saponins, flavonoids and coumarins.
