Anthocyanins are naturally occurring compounds that are responsible for a wide variety of colors in many plants, fruits and vegetables. In this study, the extraction of natural anthocyanins from Vietnamese Carissa carandas L. beverage was optimized using response surface methodology (RSM). We applied a Box–Behnken design consisting of three levels and three factors. Examined factors are extraction temperature (ranging from 40 to 60°C), liquid to solid ratio (ranging from 2:1 to 4:1), extraction time (ranging from 30 to 60 min). Using 60% ethanol as solvent for the process, we determined the maximum yields of anthocyanin was 273.786 mg/L. This yield corresponds to extraction conditions of 3:1 (v/w) liquid to solid ratio, temperature of 48.10 °C with a 44.08 min extraction time. The experimental results also fit well with the proposed response model of anthocyanin yield (R2 = 0.9992). Therefore, this study suggested optimization of different extraction methods for the defatted fruit parts.

Optimization conditions for ultrasonic extraction of phenolics from litchi seed were studied using response surface methodology. A Box–Behnken design (BBD) was applied to determine the effects of extraction temperature, methanol concentration and extraction time on yield of phenolics. Then a quadratic regression model was developed and found to be statistically significant by examining its adequacy. According to the model, the maximum yield of phenolics was obtained at the theoretical extraction conditions described as follows: extraction temperature 90°C, methanol concentration 59% and extraction time 70 min. Under this condition, the experimental value was 5.48 ± 0.03% (n = 3) with gallic acid as the equivalent, which agreed with the predicted value (5.52%) closely.

Moringa oleifera is considered one of the most useful plants in the world because it's rich in bioactive substances, which employing on modern medical treatment, also can be used for many fields: pharmaceutical, food and cosmetics purposes. In this study, the response surface methodology (RSM) based on a Box–Behnken design (BBD) was employed to optimize the extraction time (X1: 20–60 min), extraction temperature (X2: 15–45 °C) and solvent-solid ratio (X3: 5–7 ml/g), to obtain a high crude of flavonoids yield from Moringa oleifera Leaves by ultrasonic-assisted extraction technique (UAE). The optimum conditions were an extraction time 23 (min), extraction temperature 44 (°C) and solvent-solid ratio 5.05 (ml/g). Under these conditions, the experimental yield was 72.65 (mg ER/g), well matched with the predicted yield 74.34 (mg ER/g) with the coefficients of determination (R2= 0.9861), thus indicating the suitability of response surface methodology in optimizing the ultrasound-assisted extraction of flavonoids from Moringa oleifera Leaves.

Phytoestrogens are phytochemicals with antioxidant activities and potential health benefits. Their contents in soy germ is the highest compared to that in parts of soy seed. Response surface methodology (RSM) using Box Behnken Design of four factors was employed to optimize the extraction conditions for phytoestrogens. The Box Behnken Design with five replicates at central point was applied. The four independent variables investigated in this experiment were extraction time (X1) 60-120 minutes, solvent/solid ratio (X2) 8-12, extraction pH (X3) 8-10, ethanol concentration (X4) 50-70%. The high coefficient values indicated that the variables were fitted to the regression for the total phytoestrogens (R2 = 0.9887). Optimum conditions for maximizing total crude phytoestrogen content were 90 minutes for the extraction time, 12/1 for the extraction ratio, 9 for the extraction pH, and 65%  for the ethanol concentration.

Homogenate Extraction

Saffron, which has many kinds of biological activities, has been widely used in medicine, cosmetics, food, and other fields of health promotion industries. Crocins are the main component of saffron (Crocus sativus L.). At present, most of the extraction methods for crocins require long time or special instruments to complete the process and some of them are not suitable for industrial production at present. In this article, homogenate extraction technology which is a convenient and efficient method was developed for crocins extraction from saffron. Firstly, the influences of extraction voltage, extraction time, ethanol concentration, and temperature on crocins yield were studied by single factor experiments; and then response surface methodology (RSM) was used to optimize levels of four variables based on the result of single factor experiments. Results showed that the optimum extraction process conditions for crocins were as follows: extraction voltage, 110 V; ethanol concentration, 70%; extraction temperature, 57°C; and extraction time, 40 s. Based on these conditions, the extraction yield of crocins can reach 22.76% which is higher than ultrasonic extraction method. Therefore, homogenate extraction is an effective way to extract crocins from saffron with higher extraction yield and shorter extraction time.

Quercus Infectoria

This current study focuses on the modelling and optimization of supercritical fluid extraction of Quercus infectoria galls oil. In this case, response surface methodology (RSM) and artificial neural network (ANN) were applied for the modelling and prediction of extraction yield of galls oil. A 17-run Box-Behnken Design (BBD) was employed to statistically optimize the process parameters of SC-CO2 extraction of Quercus infectoria galls at a condition as follows: pressure (5000, 6000, 7000 Psi), temperature (40, 50, 60°C) and extraction time (30, 45, 60 min). The maximum yield of the extracted oil is1.12 % and the optimum conditions are at an extraction pressure of 5574 Psi; extraction temperature of 75°C and extraction time of 54 min. Under the optimal conditions, the experimental results agree with the predicted values obtained through analysis of variance (ANOVA). This indicates a successful response surface methodology and highly satisfactory goodness of fit of the model used. The analysis of experimental design for process optimization results demonstrates that temperature and extraction time are the main parameters that influence the oil extraction of Quercus infectoria.
