Rose concrete obtained from Rosa damascena Mill. was fractionated by supercritical CO2 extraction at 80 bar pressure and 40°C temperature by using a
The system poly(lactic-co-glycolic) acid/ piroxicam (PLGA/PX) was selected, as a model system, to evaluate the effectiveness of supercritical carbon dioxide (SC-CO(2)) extraction of the oily phase (ethyl acetate) from oil-in-water emulsions used in the production of polymer/drug microspheres for sustained drug release.

Rose concrete obtained from Rosa damascena Mill. was fractionated by supercritical CO2 extraction at 80 bar pressure and 408C temperature by using a
An 'absolute' is a liquid product obtained by post- processing a concrete with ethanol and subse- quently removing the solvent. A 'volatile oil' is a liquid product obtained by post-processing a con- crete by steam distillation. An 'essential oil' can be defined as the volatile material present in plants [l].
Supercritical CO2 extraction was used to post-process a solid rose extract produced by. at 15 bar and 0 OC, were the optimum process conditions to produce a volatile rose oil. supercritical extraction, fractionation, rose concrete, rose oil.

In the present study rose oil was extracted from the petals of four Rosa species i.e. R. damascena, R. centifolia, R. borboniana. sure CO2 techniques (
