“…Fractions from coriander seeds (Coriandrum sativum) were obtained using supercritical carbon dioxide using a semi-continuous lab-scale process, and tested for antioxidant activity [11]. The extraction of carotenoids from crude palm oil was carried out in a dynamic supercritical fluid extraction [12]; effects of operating pressure and temperature, flow rate of the supercritical CO 2 , and sample size of feed used on the solubility of palm carotenoids were investigated. Sage (Salvia officinalis) is a popular kitchen herb and is a member of the mint (Labiatae) family.…”

A qualitative analysis of supercritical fluid extraction (SFE) of the medically useful compound, sage <i>(Salvia officinalis)</i> is presented in this study. Carbon dioxide was used as a supercritical solvent. Effects of operating conditions such as temperature, pressure, and extraction time were investigated. The effect of addition of cosolvents was also studied. The extracted useful compounds were identified and analyzed using GC-MS chromatography. The analysis of the extract obtained by SFE showed certain significant major compounds that are considered medically important. These major compounds are 1R-.alpha.-Pinene, D-Limonene, l-Camphene, and b-Pinene, and Eucalyptol. Although, there was no consistent trend with respect to the effect of the studied parameters on the composition of the extract, the selectivity of these major compounds are dependant on the operating conditions, manily the operating pressure. An increase in the pressure resulted in an increase in herb extraction yield; this is true for certain group of extracts, while the inverse is also true for other group of compounds. The effect of certain cosolvents on the extractability of sage showed a significant improvement of the yield of some particular constituents of sage

“…In addition to being a raw material for MAG production, CPO is also a potential source of natural carotenoids as they are present at up to 500-700 ppm (Wei et al, 2005). To extract and recover carotenoids from CPO, several methods have been developed.…”

Summary Monoacylglycerol (MAG) was produced from crude palm oil (CPO) by the enzymatic glycerolysis reaction in organic solvents. The optimal conditions for MAG production from CPO were: the use of a mixture of tert‐butanol and hexane (1:1) as the organic solvents; an immobilised lipase of 40%; a molar ratio of glycerol to CPO of 8:1 with 4% of water content in the glycerol; and an initial CPO concentration of 10%. A maximum yield of 74.3% MAG was obtained with an initial production rate of 42.3 mg MAG mL−1 h−1. By converting CPO to the more polar MAG, the efficiency of recovery of carotenoids by adsorption column chromatography was improved up to 75.7% from 55.1% when using unconverted CPO. This study provides information that will be useful for developing an efficient and cheaper industrialised process for the production of MAG from CPO and recovery of carotenoids from the reaction product.

“…The highest overall oil yield was obtained at pressure 25 Mpa (10.22 %), while the lowest pressure of 10 Mpa generated only 1.92%. This phenomenon can be easily explained by the basic principle of sub-critical fluid extraction which states that as the pressure increases the density of sub-critical CO2 approaches of a liquid, it will result in an increase in the solvating power [11]. Futhermore, as the density of solvent increased, the intermolecular interaction of solutes also rose [12].…”

Abstract-This study talks about the experiments involving sub-critical carbon dioxide extraction of palm oil from treated palm mesocarp to determine palm oil yield and concentration of beta-carotene. For comparison, the conventional method of Soxhlet Extraction with six different solvents was used. The overall oil yield was measured as weight of oil per weight of sample, while anti-oxidant activity was determined using 2,2-diphenyl-1-picryihydrazyl radical scavenging method. The sub-critical extraction was conducted at a constant temperature of 30˚C and four different pressures of 10 MPa, 15 MPa, 20 MPa and 25 MPa. The sub-critical extraction produced high concentration of beta-carotene than Soxhlet extraction, even though the oil yield was lower. Furthermore, the anti-oxidant analysis showed a similar trend as the concentration of beta carotene. The best condition of sub-critical extraction was obtained at 25 MPa and 30˚C.
