摘要: A novel chitosan-based nnicrocapsule containing patchouli oil was developed by a non-toxic procedure for the purpose of improving the stability of patchouli oil and achieving a durable controlled release effect. The microcapsules were characterized in case of morphology, particle size and size distribution, infrared spectrum, and the drug controlled-release properties of nnicrocapsules were investigated under constant temperature of 25 degrees C. The results indicated that the microcapsules were spherical in shape with good dispersibility and smooth surface, and the particle size of microcapsules ranged from 1 to 10 mu m. The controlled-release of patchouli oil could still be remained about 60% in the microcapsules after 10 days, which demonstrated that the stability of patchouli oil were effectively improved after being encapsulated in microcapsules. It is believed that this study will not only provide a novel chitosan-based microcapsule production containing patchouli oil, but also promote the applications of microcapsule technology for improving the bioavailability of active volatile oils.
