Blueberry wine residues produced during the wine-brewing process contain abundant anthocyanins and other bioactive compounds. To extract anthocyanins from blueberry wine residues more efficiently, a novel procedure of ultrasound-assisted deep eutectic solvent extraction (UADESE) was proposed in this work. The extraction process was optimized by response surface methodology coupled with genetic algorithm. The optimum extraction parameters to achieve the highest yield of anthocyanins (9.32 ± 0.08 mg/g) from blueberry wine residues by UADESE were obtained at water content of 29%, ultrasonic power of 380 W, extraction temperature of 55 °C, and extraction time of 40 min. The AB-8 macroporous resin combined with Sephadex LH-20 techniques was used to purify the crude extract (CE) obtained under optimum extraction conditions and analyze the anthocyanins composition by HPLC-ESI-MS/MS. The cyanidin-3-rutinoside with purity of 92.81% was obtained. The HepG2 antitumor activity of CE was better than that of the purified anthocyanins component. Moreover, CE could increase the intracellular reactive oxygen species levels and the apoptosis, and arrest HepG2 cells in the S phases. These findings provided an effective and feasible method for anthocyanins extraction, and reduced the environmental burden of this waste.

Ultrasonic technology was applied for phenolic compounds extraction from the Pinus koraiensis bark (PKB) and response surface methodology (RSM) was used to optimize the effects of processing parameters on phenolic compounds yields. When ultrasonic power 160W,three independent variables were ultrasonic extraction time (X1 20-40min), ratio of water to raw material (X2 1:20-1:40 g/mL)and ethanol concentration(X3 20%-60%), respectively.The optimal extraction conditions of phenolic compounds were determined as follows: Ultrasonic extraction time 30.61 min, ratio of water to raw material 30.79 mL/g and ethanol concentration 42.2%. Under these conditions, the experimental yield of phenolic compounds was 8.2409 ± 0.0648‰, well matched with the predicted models with the coefficients of determination (R2) of 0.9920, which was agreed closely with the predicted value (8.2963‰).

Moringa leaves were used as raw materials, ethanol and ammonium sulfate were used to construct a aqueous two-phase system to extract the flavonoids from Moringa leaves. The solid-liquid ratio, ethanol content, ultrasonic extraction time, and ultrasonic extraction temperature were selected as single factors, and the extraction process of flavonoids was optimized through single-factor experiments and orthogonal experiments. The optimal process was: 1:110 of solid-liquid ratio, 45 % of ethanol concentration, 15 minutes of ultrasonic extraction time, 70 °C of ultrasonic extraction temperature. Under this condition, the extraction rate of Moringa leaf flavonoids reached 8.37 %.

In this paper, the ultrasonic extraction method of Oligomeric Proantho Cyanidin with chestnut shells as raw materials is studied. Using single factor method we study the effects of different extraction time, extraction reagent, extracting agent concentration and ultrasonic power on the extraction rate of Oligomeric Proantho Cyanidin. After analyzing these various factors, we make the orthogonal experiment with the factors including extraction time, extraction agent concentration, extraction temperature, solid-liquid ration, and get the optimal conditions. The experimental results show that the optimum extraction conditions are as follow: time of 30 min, extracting agent of 40% (v %) ethanol aqueous solution, extraction temperature of 40 °C, solid-liquid ratio of 1: 25 g/mL and ultrasonic power of 100 w; under these conditions the extraction rate of Oligomeric Proantho Cyanidin is 3.418%.

The extraction processing of lycopene from watermelon was investigated in this paper. Based on single factor experiments, response surface methodology (RSM) was adopted to study the key parameters such as number of extraction, extraction temperature, extraction time in order to increase extraction rate of lycopene. A second order quadratic equation was established and the applicability of model and interaction involved factors on predicting the lycopene extracting content was verified. The results indicated that the optimum extraction conditions were hexane (containing 2% dichloromethane) as extraction solvent, ratio of solvent to raw material of 3:1 (mL/g), number of extraction of 2, extraction time of 1.9 h and extraction temperature of 29.8°C. Under these conditions the extracting content of lycopene was 14.71±0.22 mg/kg, which is well in agreement with value predicted by the model.
