Ion.Appl. Sci. 2021, 11,14 ofIn the UAE experiments, we didn’t obtain a fantastic trend for the response variables; so, from our final results, the standard extraction allowed us the greater recovery in the bioactives from Cornus mas fruits. Additionally, the antioxidant power of cornelian cherry fruits is dependent upon the genotype (cultivar) also the geographical region of its cultivation, the climatic condition, the maturity, and the collection or storage and preparation circumstances [41]. Dumitrascu et al. [15] reported that for the cornelian cherry from a controlled , culture, the TPC ranged from two.04 g GAE/ 100 g dw to four.42 g GAE/100 g dw for the extracts obtained by ultrasound-assisted extraction. For the methanol extracts obtained at 30 C beneath ultrasound action for 60 min, Cosmulescu and Trandafir [40] identified an average content of flavonoids of 59.37 mg QE /100 g for the cornelian cherry collected in the village of Baita, Hunedoara county. The cornelian cherry fruits possess high antioxidant Pinacidil Biological Activity activity with a massive variation amongst Cornus mas genotypes. The six wild cornelian cherry fruits from the western a part of Romania possess a variation with the total antioxidant activity involving 1.24 and two.71 mMol TE/ 100 g FW. The greater antioxidant activity was discovered for the genotype collected in the village of Hartagani, Hunedoara county [42]. three.3. Optimization and Validation of Extraction Circumstances The experimental results presented in Section three.1 for the conventional extraction of bioactive compounds in the cornelian cherry revealed that the extraction with the TPC, the TFC, and the TAA might be fitted to a second-order polynomial, according to the R2 values presented in Table two. The optimization section is obtained in the statistical plan that gives the optimal circumstances and also the predicted values for the variables. As the fitting for the UAE experiments is poor, no optimal circumstances are going to be calculated as there isn’t any statistically significant impact of any on the experimental variables around the responses studied. The final model for standard extraction of cornelian cherry fruits with regards to 3 factors, coded with X1 –temperature ( C); X2 –time (min); and X3 –ethanol concentration was as follows: TPC = 169.67 – 1.374X2 – 1.1097X3 0.04019X1 two 0.017X2 two TFC = 1.02 0.08X3 – 0.00074X3 2 TAA = 142 – 1.03X2 – 0.522X3 0.043X1 – 0.01125X1 X2 0.018X2(7) (eight) (9)Ultimately, employing the optimization tool offered by the Statgraphics 18.0 statistical application it was attainable to establish the experimental circumstances that GYY4137 medchemexpress maximized the three responses simultaneously. This process tries to find the levels in the experimental variables that maximize a combined desirability function, which is a function that expresses the desirability of a remedy involving the three responses studied (TPC, TFC and TAA). The results are presented in Table five. So as to confirm the optimal parameters proposed by the polynomial equation as well as the statistical application, the experiments have been conducted with all the following parameters: 40 C, 15 min, 60 ethanol (v/v), which are the optimal extraction conditions predicted by the statistical software. For validation, the values in the experimental answers had been compared with all the values predicted by the quadratic (polynomial) model expressed by the Equations (4)6).Table 5.
