RODRIGUEZ-AMADO, Jesús Rafael et al. PHYSICOMECHANICAL AND COMPACTION CHARACTERIZATION OF TABLETS OBTAINED FROM A NATURAL DRY EXTRACTS. RTQ [online]. 2011, vol.31, n.2, pp. 233-241. ISSN 2224-6185.
The aim of this work was to evaluate the compaction behavior and the physical mechanical characterization of tablets, obtained from a natural dry extracts of the leaves of Tamarindus indica L. The Heckel analysis was used to characterize the dry extract compaction behavior. The dry extract has a mixed mechanism of consolidation: plastic and brittle fracture, showing a mean yield pressure of 179,85 MPa. The compact’s tensile strength increase with the augment of compaction pressure. Compacts must be obtained at compaction pressure below 90MPa because of; at superior compaction pressure disintegration time increases over 30 min. The friability of the tablets in any case is superior to 1 percent.
