“…Nowadays, several studies concerning the evaluation of experimental solubility data for different solutes in SC-CO 2 have been correlated through empirical equations. These results, related to the use of density-based models such as the ones proposed by Chrastil (1982) and del Valle and Aguilera (1988), have been extensively presented in the literature (Chen, Zhao, & Yu, 2003;Danielski, 2002;Daood et al, 2002;Gaspar et al, 2003;Jouyban, Chan, & Foster, 2002;Kim & Hong, 1999;Murga, Sanz, Beltrán, & Cabezas, 2002;Tolic, Zekovic, & Pekic, 1996).…”

“…Because of a lack of experimental data on α-bisabolol solubility in CO 2 , a direct assessment of our results is not possible. In view of this, we compared the α-bisabolol solubility values we obtained with those of volatile oils rich in α-bisabolol, measured previously and available from the literature. ,, …”

Measurement and Correlation of α-Bisabolol Solubility in Near-Critical Carbon Dioxide

The solubility of (−)-α-bisabolol, ((−)-6-methyl-2-(4-methyl-3-cyclohexen-1-yl)-5-hepten-2-ol), a monocyclic sesquiterpene alcohol, in sub-and supercritical CO 2 was measured at the temperatures (313.2, 323.2, and 333.2) K and pressures ranging from (7 to 12.5) MPa by a dynamic method. To the best of our knowledge, there are no previous measurements of α-bisabolol solubility in near critical CO 2 reported in the literature. The solubility isotherms were in the crossover region; the maximum mole fraction of α-bisabolol in CO 2 , 9•10 −3 , was therefore at 313.2 K and 11.5 MPa, the maximum pressure applied at this temperature. The Soave−Redlich−Kwong equation of state (SRK-EoS) was employed to correlate the experimental data and an acceptable agreement was obtained. Furthermore, the thermophysical properties of the solute required by the modeling were estimated and reported.

“…solvent density of 0.568 g mL -1 ). On the basis of our previous SFE investigations of different aromatic plants (and other raw materials) carried out during last 20 years (12,(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28), the best combination of pressure and temperature for EO separation (isolation) is 100 bar and 40 o C -the resulting extracts are most similar to "classical" EOs. The other extracted compounds -OEC ( Table 3, the last row) from the extracts (mass percent from 40.44 to 58.21%) are not (and could not be, without some kind of derivation, such is esterification) detected by the GC-FID (or GC-MS) method.…”

Basil (Ocimum basilicum L.) essential oil and extracts obtained by supercritical fluid extraction

et al. 2015

View full text Add to dashboard Cite

The extracts obtained from sweet basil (Ocimum basilicum L.) by hydrodistillation and supercritical fluid extraction (SFE) were qualitative and quantitative analyzed by GC-MS and GC-FID. Essential oil (EO) content of basil sample, determined by an official method, was 0.565% (V/w). The yields of basil obtained by SFE were from 0.719 to 1.483% (w/w), depending on the supercritical fluid (carbon dioxide) density (from 0.378 to 0.929 g mL-1). The dominant compounds detected in all investigated samples (EO obtained by hydrodistillation and different SFE extracts) were: linalool, as the major compound of basil EO (content from 10.14 to 49.79%, w/w), eugenol (from 3.74 to 9.78%) and δ-cardinene (from 3.94 to 8.07%). The quantitative results of GC-MS from peak areas and by GC-FID using external standard method involving main standards, were compared and discussed.
