Optimization of the Ocimum basilicum L. extraction process regarding the antioxidant activity

Abstract

The levels of input variables (temperature and extraction solvent) that optimize a particular response (total phenols content, total flavonoids content and antioxidant activity) of the Ocimum basilicum L. extraction process were determined by the response surface methodology (RSM). The influence of theextraction temperature on extraction process was investigated in the range from 33.8ºC to 76.2ºC, as well as of extraction solvent ethanol, in the range of concentrations from 21.7% to 78.3%. For the preparation of basil dry extract, characterized with minimal IC50 value, the calculated optimal values of temperature and ethanol concentration were: 75.33ºC and 73.66% (w/w).

Multi-response optimization of factors affecting ultrasonic assisted extraction from Iranian basil using central composite design

“…Among the many classes of RSM designs, central composite design (CCD) is among the most popular methods due to its simple structure and efficiency (Correia, Gonçalves, da Cunha Jr., & Ferraresi, 2005). Based on the best of our knowledge, there are only few reports on optimization of antioxidants extraction from basil using RSM technique and pressurized liquid extraction (PLE) and maceration extraction methods (Hossain, Brunton, Martin-Diana, & Barry-Ryan, 2010;Juntachote, Berghofer, Bauer, & Siebenhandl, 2006;Vidović et al, 2012). However, no research article regarding the RSM optimization and investigation of antioxidants extraction from basil using UAE method was found.…”

Optimization ofSatureja montanaExtraction Process Considering Phenolic Antioxidants and Antioxidant Activity

“…Due to the toxicity of synthetic antioxidants, the pharmaceutical and food industry are paying much attention to the extraction of antioxidants and the creation of antioxidant supplements from different natural sources (herbs, fruit, and vegetables) (9). Extracts from natural plants, as carriers of antioxidant activity and antioxidant compounds, can be obtained by different extraction techniques, using different extraction solvents and/at different extraction conditions (temperature, time, pressure, etc.).…”
