Component Analysis of Volatile Oil from Chrysanthemum morifolium by Supercritical Carbon Dioxide Extraction

Vetiver Oil Extraction Optimization Using Supercritical Carbon Dioxide Fluid

Extraction of volatile oil from aromatic plants with supercritical carbon dioxide: experiments and modeling.

An overview of the studies carried out in our laboratories on supercritical fluid extraction (SFE) of volatile oils from seven aromatic plants: pennyroyal (Mentha pulegium L.), fennel seeds (Foeniculum vulgare Mill.), coriander (Coriandrum sativum L.), savory (Satureja fruticosa Béguinot), winter savory (Satureja montana L.), cotton lavender (Santolina chamaecyparisus) and thyme (Thymus vulgari...

Isolation of Crithmum Maritimum Volatile Oil By Supercritical Carbon Dioxide Extraction

Dried and ground leaves of Crithmum maritimum were used as a matrix for supercritical extraction of volatile oil with CO2. Operative conditions were: extractor, 90 bar and 50 °C for 240 min; first separator, 90 bar and –10°C; second separator, 15 bar and 15 °C. GC/MS analysis of the leaves volatile oil revealed that it mainly consisted of: para-cymene, βphellandrene, γ-terpinene, thymol methyl ...

Supercritical Carbon Dioxide Extraction of Borage Seed Oil

The oil from the seeds of Borago officinalis L. (borage) is a major commercial source of ?-linolenic acid. The fatty acid has a great potential therapeutic value in the treatment of several diseases. In the present work the efficiency of high pressure extraction of borage seed oil containing ?linolenic acid in high concentrations was investigated. Extraction was performed by semicontinuous flow...

Supercritical Carbon Dioxide Extraction of Volatile Flavor Compounds from Artemisia annua

The aromatic compounds of Artemisia annua were extracted by supercritical carbon dioxide. Supercritical carbon dioxide extraction of volatile flavor compounds from Artemisia annua was performed at pressure 150bar and temperature 40oC. The flow rate of CO2 was 20 g/min and the flow rate of ethanol as an entrainer was 5% of CO2 used. The extraction time was 1 h. The trapped sample by cold trap 1 ...
