Objective : This study aimed to obtain standardised dry extracts of Miracrodruon urundeuva Allemão using spray-dryer and evaluate the stability of the extracts. Methods : It evaluated the drying parameters: Proportion of colloidal silicon dioxide (CSD) (10, 15 and 20%), inlet temperature (160, 170 and 180 °C) and feed rate (4, 6 and 8 ml/min). The study of the accelerated stability of dry extract occurred in temperature of 40 °C (±2 °C) and relative humidity of 75% (±5%) for 6 mo. The anti-inflammatory activity of the dry extract was evaluated in Swiss mice by the paw edema method. Results : Variations in drying conditions did not represent significant variations in yields of the process. The drying temperature and feed rate significantly influenced the concentration of quercetin (p≤0.05). The increase in inlet temperature and feed flow promoted the increase of quercetin concentration in the extracts. The stability study showed that the concentration of quercetin in dry extract was stable over a period of 6 mo. The dry extract showed anti-inflammatory activity in mice orally. Conclusion : A condition of 10% of colloidal silicon dioxide with an 180 °C inlet temperature and a feed rate of 8 ml/min was considered the most adequate for obtaining the extracts and the drying process resulted in stable dry extracts and the quercetin was a suitable biomarker for monitoring the process.
