Abstract: Focusing on the comprehensive utilization of grape skin, the studies on the optimum conditions of the extraction of grape skin essential oil by supercritical fluid were carried out. The primary and secondary effect factors on the extraction of grape skin essential oil by supercritical fluid were as followed: time > temperature > pressure. The optimum conditions were: extraction time 35min, extraction temperature 35℃ and extraction pressure 30MPa.

Key words: supercritical fluid extraction, grape skin, essential oil, optimum condition
