“…These findings are in agreements with the results of Hashemi et al 11 who found application of ultrasound in extraction of oil enhanced tocopherol and tocotrienol compounds of extracted oil. This could be due to the fact that during UASE, the collapse of cavitation bubbles generates short-lived localized hot-spots with extremely high local temperature and pressure 24 that can influence the stability of the tocol compounds, which also depends on their chemical structure 25 . P. khinjuk hull oil is considered a valuable source of tocopherols because the tocopherols content reported for this oil is much higher than that of common oils such as sunflower, cottonseed, soybean, canola, and palm oil.…”

“…In the last years, novel sustainable extraction techniques such as Ultrasound-Assisted Extraction (UAE), Microwave-Assisted Extraction (MAE), Supercritical CO2 Extraction, Supercritical Fluid Extraction (SFE), Accelerated Solvent Extraction (ASE) and Pressurized Hot Water Extraction (PHWE) or Subcritical Water Extraction (SWE) which allow to reduce extraction time and solvent consumption, increase nutraceutical yield and improve plant extract quality (1)(2)(3)(4)(5)(6)(7)(8)(9)(10). Subcritical water extraction is called green technology because it is a rapid and efficient recovery method as compared with conventional extraction methods.…”

Mandarin peel, which discarded as by-product at large amounts during fruit juice production, is a valuable source of antioxidant compounds in the food industry. The aim of this study was to investigate the effect of extraction temperature and static extraction time on antioxidant activity and phenolic compounds during subcritical water extraction. The antioxidant activity of subcritical water extracts were determined by 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay as IC 50 , ferric ion reducing antioxidant power (FRAP) and total antioxidant potential assay using Cu(II) complex as an oxidant (CUPRAC). As the IC 50 value of the subcritical water extracts obtained from mandarin peel decreased 40.8 times, FRAP and CUPRAC values increased 66.9 and 34.2 times with increasing extraction temperature from 50 to 180°C for 5 min, respectively. Besides, total phenolic content (TPC) of subcritical water extracts increased 4.9 and 5.0 times from 50 to 180°C for 5 and 15 min whereas, 9.6 and 9.9 times increase was obtained for total flavonoid content (TFC) in the subcritical water extracts, respectively.

“…This is because the increase of ethanol concentration leads to enhanced mass transfer dynamics, solvents and honeysuckle getting full access, and then the contents of chlorogenic acid dissolved increased [11]. When the ethanol concentration reached a certain level, some of chlorogenic acid was difficult to be dissolved by high concentration of ethanol, and also lead to the increase of the alcohol-soluble impurity content, resulting in a loss of chlorogenic acid content [12]. Moreover, the greater of ethanol concentration, the more difficult to refine chlorogenic acid and it will cause wasted and the cost of production increased.…”

The ultrasound-assisted extraction of chlorogenic acid from honeysuckle was modeled using response surface methodology. A three-level-three-factor Box-Behnken design was employed to optimize three extraction variables, including extraction temperature (X1), ethanol concentration (X2), and soak time (X3), for the achievement of high extraction yield of the chlorogenic acid. The optimized conditions are extract temperature of 80˚C, ethanol concentration of 70.37%, soak time of 9.35 h. Under this optimized conditions, the experimental yield of chlorogenic acid is 1.918%, which is well matched with the predicted yield of 1.929%.
