- Abstract
Objective To optimize the extracting conditions of fucoxanthin from Sargassum horneri by response surface methodology (RSM). Methods Fucoxanthin was extracted from Sargassum horneri with ethanol as solvent by ultrasonication. The effects of ethanol concentration, solid-liquid ratio, extraction temperature and time on the extraction of fucoxanthin from Sargassum horneri were studied. Based on the results of single factor experiments, Box-Benhnken design center combination method of 4 factors and 3 levels experimental design was applied to further optimize the extraction conditions using the extraction yield as response value. Results The response surface interaction analysis showed that the optimum extraction conditions for ultrasonic extraction were solid-liquid ratio at 1:100, initial temperature at 60 °C, extraction time at 40 min and ethanol concentration at 70%. Under the optimized conditions, the extraction yield of fucoxanthin from Sargassum horneri by ultrasonic extraction was up to 1092 μg/g, which was highly consistent with the predictive value of 1183 μg/g. Conclusion By response surface optimization, the optimum conditions for ultrasonic extraction of fucoxanthin from Sargassum horneri by ethanol solution were obtained, which increased the extraction amount of fucoxanthin.
