Title: Response surface methodology as an approach to optimization of flash-extraction of flavonoids from rose fruit
Abstract: Flash-extraction technology was used to extract flavonoids from rose fruits. Based on single factor experiments,extraction conditions such as solvent concentration,material / liquid ratio and extraction voltage were optimized by response surface methodology. The results showed that each of the three extraction conditions affected flavonoids extraction significantly. The optimized conditions were as follows:60% ethanol concentration,1∶ 120 material/liquid ratio,and 120V extraction voltage,resulting in an extraction content of 57. 84mg/g for flavonoids. As a conclusion,flash-extraction was an effective and efficient method to extract flavonoids from rose fruits,response surface methodology could well optimize the extraction technology.
