Abstract
Experimental results concerning the processing feasibility of using supercritical CO2 were reported for the extraction of epicuticular wax fromEphedra herb. Subsequently the isolability of nonacosan-10-ol from the total extract of epicuticular wax was evaluated by TLC and gas chromatography. Also, Soxhlet extractions ofEphedra herb by n-hexane and chloroform were performed and these results were compared with those obtained by supercritical CO2 extraction. As a result, we could demonstrate that supercritical CO2 can be an economical alternative to the organic solvents in processing the medicinal plant.
