Ultrasonic Assisted Extraction

Ultrasonic-Assisted extraction (UAE) was applied for saponins extraction from Ophiopholis mirabilis and response surface methodology (RSM) was used to optimize the extraction technology. A first set of experiments were designed to optimize water bath temperature, ethanol concentration, the ratio of liquid to solid, ultrasonic time (min) and ultrasonic power (W) as the main variables affecting the extraction effect. A Box-Behnken design consisting of 15 experimental runs was then applied and a second-order polynomial model was used to explain the interactions between the main factors and the yield of saponins. The developed mathematical model was found to fit well with the experimental data and the optimized conditions were ultrasonic pretreatment time 30.9 min, ethanol concentration 64%, liquid /solid ratio 35:1, ultrasonic power 300W and water bath 70°C. Corresponding saponins content was 0.574%.

The viability of using the waste obtained in the manufacture of sugar from sugarcane for the production of biodiesel has been analyzed. Two fundamental stages are necessary to obtain biodiesel; the first stage is the extraction process from the waste oil materials and the second is the transesterification reaction. Four techniques, Soxhlet, orbital shaker extraction, ultrasonic-assisted extraction, and supercritical fluid extraction, have been analyzed. For Soxhlet, orbital shaker extraction, and ultrasonic-assisted extraction, the organic solvent (hexane) was maintained for all experiment. In supercritical fluid extraction two solvents were evaluated: pure CO2and mixtures of CO2and 5% (v : v) methanol. The reaction kinetics of the transesterification reaction with an acidic catalyst and a basic catalyst were analysed. The results show that the supercritical extraction process produces a better product for the subsequent transesterification reaction. This finding is attributed to the high selectivity of carbon dioxide in the recovery of fatty acids and triglycerides in comparison with other solvents.
