【Abstract】 In recent years, the supercritical fluid extractions have a great development and more widespread application in our country. This paper made a summary of the basic principles of the supercritical carbon dioxide extraction, the extraction technology of natural ethereal oil of perfume material by supercritical carbon dioxide and its influence factors, such as graininess of material, extraction pression, temperature, time, and efflux of carbon dioxide. The usage of entrainment reagent and analysis methods of component of ethereal oil was also summarized. A vast range of prospect of the extraction of natural ethereal oil of perfume material by supercritical carbon dioxide was predicted in this paper.更多还原
