Eucalyptus volatile oil was isolated by supercritical CO 2 extraction with a fractional separation technique. GCยฑMS analysis of the various fractions obtained at dierent extraction and fractionation conditions allowed the identiยฎcation of the best operating conditions to isolate the volatile oil. A
Supercritical fluid extraction (SFE) of plant materials began with industry and moved to the laboratory, along with supercritical-fluid chromatography, as high pressure systems became available. SFE has been applied to several groups of non-polar compounds, including essential oils, other flavour an
## Abstract A cellโfree extract, which was isolated from the leaves of mature __Catharanthus roseus__ plants by a previously published procedure, __does not__ convert a mixture of secologanin and radiolabelled tryptamine to vindoline, as was recently claimed. The radioactivity in the purified alkal
