dc.description.abstractPharmacognostic and phytochemical study of the stem and root,,of Microgramma squamulosa (Kaulf.) Sota. Erva silvina, or Microgramma squamulosa (Kaulf.), Sota belongs to the family Polylodiaceae and is traditionally used as an antiulcer agent. Previous assays showed results that confirm the antiulcer action of the ethanolic extract and some fractions of the stem of M squamulosa and results showing no significant toxicity in the acute model, both made in rats Due to the significant results obtained in this previous work, it becomes important to furnish tools to identify the vegetal drug. The species is' an epiphyte that bears lanceolate scales totally covering the long-creeping brown-colored stem. Adventicious roots can be seen in the abaxial portion of, the-stem, while the leaves appear in the adaxial portion. Elements which contribute to the histological identification are: peltate lanceolate -haired scales, sclereids, meristeles (amphicribal bundles) and scalariform the roots. Phytochemical screening, and TLC tracheids in the stem; strip hairs and sclereids in analysis showed the presence of flavonoids and tannins which may be related to the anti,ulcer the plant as well as the characterization of activity. Results shown may help the identification of the fragmented vegetal drug and if it is presented as powder or as extract.en
