Ultrasound is one of emerging technique's which is being investigated extremely on food applications and extraction process. In this study, ultrasound-assisted solvent extraction was employed to extract vegetable oil from coriander ( L.) seeds. A response surface model was applied to determine the best condition of extraction concerning the independent factors (COY % and DPPH %). In addition, ultrasound variables were the sample solvent ratio, amplitude level, temperature and time. The best condition of extraction was obtained for sample solvent ratio of 1:13 (g/mL), amplitude level of 82 (%), temperature of 45 (°C) and extraction time of 9 (min), being the maximum point of oil yield and antioxidant activity (30.74-72.05%), respectively. Fatty acid profile of oil has been shown as a rich source of petroselinic acid (C18:1)-12, making up 76% of all fatty acids. TGA analyses revealed that 82% (by weight) of oil is thermally stable up to 224 °C.

Triterpenoids are known for their promising biological activities, and there is a growing focus on green extraction methods for these compounds. In this study, ultrasound-assisted deep eutectic solvents were employed to extract triterpenoids from persimmon leaves, with choline chloride-lactic acid identified as an effective green solvent. The extraction conditions were carefully optimized using response surface methodology, resulting in an extraction efficiency of 12.

In this study, the effectiveness of three choline chloride (ChCl)-based deep eutectic solvents (DESs) formed using malonic acid (MalA), glycerol (Gly), and glucose (Glu) as hydrogen bond donors and two conventional solvents (50% methanol and 50% ethanol) for ultrasonic-assisted extraction (UAE) of antioxidant compounds from four herbs (chamomile, lemon balm, nettle, and spearmint) were estimated. The antioxidant capacity (AC) of the obtained herb extracts was determined by the modified 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH), and cupric reducing antioxidant capacity (CUPRAC) methods. Profiles of phenolic acids, flavonoid aglycones, and flavonoid glycosides in the green and conventional herb extracts were quantitatively analyzed using ultra-performance liquid chromatography (UPLC).

Purple corn pericarp, a processing waste stream, is an extremely rich source of phytochemicals. Optimal polyphenol extraction parameters were identified using response surface methodology (RSM) by combining a deep eutectic solvent (DES) and ultrasound-assisted extraction (UAE) method. After DES characterization, Plackett-Burman design was used to screen five explanatory variables, namely, time, Temp (temperature), water, Amp (amplitude), and S/L (solid-to-liquid ratio).
