The isolation of cananga oil by a new process, Instantaneous Controlled Pressure Drop (DIC), was investigated. This process consists in heating the dry cananga (Cananga odorata Hook. fil. et Thomson, forma macrophylla) flowers for a short time period by steam, followed by an abrupt pressure drop into a vacuum (about 5 kPa). This pressure drop provokes auto-vaporization of the volatile compounds...

chemical composition of the essential oil of the fruit of ferula assafoetida l. obtained by steam distillation solvent extraction methodhas been studied by gc/ms for the first time. fifty-four components, comprising 96.9% of the total oil, were identified.epi-α-cadinol (23.15 %), germacrene b (10.98 %), α-gurjunene (6.18 %), (z)-1-propenyl secbutyl disulfide (5.89 %), 5-epi-7-epi-α-eudesmol (4....

Star anise (Illicium verum) is widely used as a medicinal herb and spice. The extracts, essential oil oleoresin, can be produced by hydro-distillation steam distillation, while solvent supercritical fluid extraction to extract oleoresin. In this work, the star distilled obtain oil, subsequently, its residue extracted get Whole grounded fruit for 8, 12, 16, 20, 24 hours, thus highest yield obtai...

BACKGROUND Plectranthus amboinicus Lour is a species which is widespread throughout tropical countries where it is widely used against respiratory tract disorders such as bronchodilator, antitussive, and expectorant conditions. OBJECTIVE This study aims to characterize the essential oil of P. amboinicus (PaEO) and produce and evaluate emulsions containing PaEO. MATERIALS AND METHODS The ess...
