Extraction Technology on the Volatile Oil from Ocimum Basilicum L. by Supercritical CO2

Abstract

Abstract: The article introduced technology of supercritical CO2 on extracting volatile oil from dry leaves of Ocimum basiliamLinn var. pilosum (wild. )Benth, putting emphasis on effects of marinating time, SC-CO2 extracting pressure, temperature and timeon the extraction efficiencies.The optimum technology parameters were investigated by the orthogonal design. The factorsinfluencing this extraction efficiency were as follows: C>A>B (A: extraction pressure,B: extraction temperature, C: extrac-tion time), the optimum extraction conditions were: marinating time 150min,extraction pressure 18MPa,extraction temperature55℃, extraction time 120min and flux 25L/min. The maximum of extraction efficiencies was up to 2.8‰.

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