Abstract: The article introduced two kinds of pilotscale experiment technology of volatile oil extracted from dry leavesof Ocimum basiliam Linn var. pilosum (wild.) Benh, by putting emphasis in comparison with the extraction rate andcomponents of volatile oil between steam distillation and superciticol CO2 (SC-CO2) extraction. The results showed thatthe extraction rate of volatile oil was about 0.89% by steam distillation and there were 13 main components in thevolatile; while the extraction ratio of volatile oil was about 2.8‰ by SC-CO2 extraction and there were 18 maincomponents. Moreover, the color and the flavor of volatile oil by SC-CO2 extraction were better than those by steamdistillation.

Key words: Ocimum Basilicum L., volatile oil, steam distillation, supercritical CO2 extraction
