【 摘 要 】

The characters pharmacognostics of leaves of Davilla elliptica St. Hil. and Davilla rugosa Poir. of Dilleniaceae family were determinated for aiming in taxonomic and quality control of vegetable drugs and phytotherapic produtcs. The specie of D. elliptica is an erect shrub, that occurs naturally in cerrado and D. rugosa is a scandent shrub of forest edge. Both are populary known as "lixeirinha", "sambaibinha" and "cipó-caboclo" and used in popular medicine as anti-inflammatory and antiulcer. The microscopic characteristics observed like strellate trichomes and sclereids in the mesophyll in D. rugosa and the idioblasts with mucilage and endodermis in D. elliptica are parameter that will be used to differentiate the species. The content obtained in tests of purity and the tannins (9.4% and 7.2%), flavonoids (0.46% and 0.9%) and mucilage (2.2% and 4.1%) of both species help in quality control of vegetable drugs since they are indistinctly used in production of phytotherapics.
