Comparison of extraction of patchouli (Pogostemon cablin) essential oil with supercritical CO2 and by steam distillation

A. Donelian, +3 more
- 01 Feb 2009 - 
TL;DR: In this paper, patchouli essential oil was extracted with supercritical carbon dioxide (scCO 2 ) under different conditions of pressure (8.5 and 14 MPa) and temperature (40 and 50 °C).
Journal ArticleDOI

Antimicrobial activity of microencapsulated lemongrass essential oil and the effect of experimental parameters on microcapsules size and morphology

Fernanda Vitória Leimann, +3 more
- 01 Mar 2009 - 
TL;DR: In this article, Lemongrass essential oil was microencapped by simple coacervation and the influence of stirring rate and oil volume fraction on the microcapsule size distribution was evaluated.
Journal ArticleDOI

Extraction of lemongrass essential oil with dense carbon dioxide

Luiz Henrique Castelan Carlson, +4 more
- 01 Sep 2001 - 
TL;DR: In this article, lemongrass essential oil was extracted with dense carbon dioxide at 23-50°C and 85-120 bar, and the composition of samples collected during the first and the last hours of the extraction experiments was analyzed by gas chromatography-mass spectrometry, and coextraction of cuticular waxes was observed.
Journal ArticleDOI

Guilherme Davi Mumbach, +6 more
- 15 Nov 2019 - 
TL;DR: In this paper, the applicability of pyrolysis of plastic solid waste (PSW) to recovery energy from PSW was performed in a thermogravimetric analyzer under an inert condition.
Journal ArticleDOI

Separation of nutmeg essential oil and dense CO2 with a cellulose acetate reverse osmosis membrane

Cinthia Bittencourt Spricigo, +4 more
- 15 Jul 2001 -
