Abstract
Granules and microparticles containing essential oils from Varronia verbenacea and Achyrocline satureioides were prepared, dried and evaluated in vitro by measuring releasing profiles, particle size, oil load, density, humidity and water activity at time zero and 60 days after production. Comparisons were also made using hard gelatin capsules. Measurements showed a significant decrease in oil load for the spray-dried particles compared to granules, and the desiccator-dried granules proved to maintain the highest oil content over the 60-day period. Moreover, gelatin capsules reduced oil losses, which is expected to increase the shelf-life and maintain the biological activity of such preparations for pharmaceutical applications.
