Resumo

The aim of this study was to investigate the physical properties of the seed coat of Tingui (Magoniapubescens) in order to evaluate the performance of this polysaccharide as an excipient for seedpelleting. The analysis was emphasized to the flow properties including particle size, particle sizedistribution, density and moisture content of the substance. The results were compared tocommercial excipients including Microcrystalline cellulose (MCC PH 101 and SMCC), Hydroxypropyl methylcellulose (HPMC E50), Polyvinil pirrolidone (PVP K29/32), lactose andcorn starch. The data showed that Tingui was found to have bulk and tap density close to HPMCand corn starch. Particle size and its distribution were fit to HPMC and PVP; however, Tingui hadmoisture content quite close to SMCC and HPMC. In general, Tingui exhibited the free-flowproperties comparable to HPMC and PVP. Energy dispersive X-ray fluorescence analysis confirmedthat the seed coat of Tingui contains elements (K, Ca, Si and Fe) composition.
