%X <i>Rhizophora mangle </i>L. is a vegetal
species with high disponibility in Cuba for guarantying
economical factibility by drug development.
Preview studies showed promissory pharmacological results by the use of this
plant in the treatment of gastroduodenal ulcers. The present work involved another
evaluation of the active extract important by the development of a new drug. It
was evaluated by intestinal absorption <i>in vitro </i>and <i>in situ </i>models
and anti-diarrheic activity in rats. The polyphenolic fractions were separated
from the aqueous extract and its cytoprotective activity was studied on gastric
ulceration induced by ethanol plus hydrochloric acid in rats. Some toxicological
studies were carried out. We made a validation of HPLC method by the analysis
of one mark in the tablet development. The aqueous extract showed high
absorption, and high anti-diarrheic effect. The low-molecular weight
polyphenolic fraction showed the highest level of gastric protection. No
toxicological signs were obtained by it. HPLC method evidenced linearity, precision, sensitivity and accuracy.
