“…The solubility of melatonin in different SC-CO 2 extraction conditions was calculated 16 by the ratio of the total mass of extracted melatonin (g) to the mass of CO 2 consumed in the extraction process as shown below: y= mass of melatonin/ mass of CO 2 = Mο/ρV ... 3where, Y is the solubility (mass fraction) of melatonin in SC-CO 2 extracts, Mo is the total mass of melatonin extracted (g), V is the volume of CO 2 (mL) used for extraction and ρ is the density of SC-CO 2 (kg/m 3 ) under different extraction conditions. The densities of SC-CO 2 under different extraction conditions (temperature, pressure) were calculated using empirical Peng-Robinson cubic equation of state as has been reported by Ghosh et al, in 2016 17 .…”

“…Optimal processing condition: To determine the optimal processing conditions of extraction of melatonin from YM seeds, the first partial derivatives of the regression equation was conducted with respect to X 1 and X 2 and set to zero. This was done by putting the second order regression equation in matrix form 17 . The point thus obtained is known as the stationary point, X S (X 1S =337.67 bar, X 2S =49.93 °C).…”

Brassica campestris Linn. (yellow mustard), a common Indian condiment, possesses melatonin as an important antioxidant. Optimization of supercritical carbon dioxide extraction (SC-CO 2) process parameters was conducted to obtain an extract having the best combination of yield of melatonin and maximum in vitro hypoglycaemic and hypocholesterolemic activities, along with a desirable balance of ω6 to ω3 fatty acids. A full factorial design and response surface methodology were employed for process optimization. Melatonin content of the extracts was obtained by high performance liquid chromatography and by liquid chromatography-mass spectrometry. The optimized extraction conditions were obtained at 300 bar, 50 °C for 120 min. This extract exhibited highest content of melatonin (660.72±41.05 ng/g of dry mustard powder), maximum in vitro hypocholesterolemic (60.11±3.89%) and hypoglycaemic (59.70±2.67µg/ml) activities and possessed minimum ω6 to ω3 (1.29) ratio with minimum erucic acid content (2.00±0.20 g/100g of fatty acid). The electron paramagnetic resonance spectroscopy of the extract (0.10±0.001 g/ml) showed 72.10±4.01% scavenging activity of DPPH radicals, establishing its strong antioxidant potency. A new Chrastil equation was developed to compute solubility of melatonin in SC-CO 2 under different extraction conditions. The SC-CO 2 extract of yellow mustard seeds could have promising use as a natural source of melatonin as well as of balanced ω6 to ω3 fatty acids.

Yellow maize kernels were subjected to supercritical carbon dioxide (SC-CO) extraction to obtain a lutein-rich extract with potential nutraceutical properties. SC-CO extraction parameters (pressure and temperature) were optimized by employing a full-factorial (3) design of experiments and response surface methodology, based on yield of lutein, antioxidant activity, and ω-6/ω-3 fatty acid ratio of the extracts. A Chrastil equation was also developed for predicting the solubility of lutein in SC-CO under different extraction conditions. The optimized extraction condition was obtained at 500 bar, 70 °C for 90 min, at which the extract was found to possess a unique combination of the highest lutein yield (275.00 ± 3.50 μg/g of dry weight), along with a well-balanced ω-6/ω-3 fatty acid ratio (3:1). Moreover, the total phenol content and antioxidant activity were also found to be the highest at this condition. This lutein-rich extract is a promising nutraceutical or dietary supplement in the food industry.
