Title: | Optimization of ultrasound-assisted extraction of polyphenolic compounds from coriander seeds using response surface methodology | Authors: | Zeković, Zoran Đurović, Saša Pavlić, Branimir |
Issue Date: | 1-Jan-2016 | Publisher: | Novi Sad: Faculty of Technology, Novi Sad | Journal: | Acta Periodica Technologica | Abstract: | Coriandrum sativum L. (coriander) seeds (CS) were used for preparation of extracts with high content of biologically active compounds. In order to optimize ultrasoundassisted extraction process, three levels and three variables of Box-Behnken experimental design (BBD) in combination with response surface methodology (RSM) were applied, yielding maximized total phenolics (TP) and flavonoids (TF) content and antioxidant activity (IC50 and EC50 values). Independent variables were temperature (40-80oC), extraction time (40-80 min) and ultrasonic power (96-216 W). Experimental results were fitted to a second-order polynomial model with multiple regression, while the analysis of variance (ANOVA) was employed to assess the model fitness and determine optimal conditions for TP (79.60oC, 49.20 min, 96.69 W), TF (79.40oC, 43.60 min, 216.00 W), IC50 (80.00oC, 60.40 min, 216.00 W) and EC50 (78.40oC, 68.60 min, 214.80 W). On the basis of the obtained mathematical models, three-dimensional surface plots were generated. The predicted values for TP, TF, IC50 and EC50 were: 382.68 mg GAE/100 g CS, 216 mg CE/100 g CS, 0.03764 mg/mL and 0.1425 mg/mL, respectively. | URI: | https://open.uns.ac.rs/handle/123456789/3951 | ISSN: | 14507188 | DOI: | 10.2298/APT1647249Z |
