Optimization of Microwave-Assisted Extraction of Proanthocyanidins from Rosa davurica Pall. Seeds by Response Surface Methodology
摘要
Abstract
The microwave-assisted extraction of proanthocyanidins (PC) fromRosa davnrica Pall. seeds was optimized using the response surface methodology. The PC content ofRosa davnrica Pall. seeds was determined to be (1.55± 0.12) g/100 g by iron salt catalysis method. The results of one-factor-at-a-time experiments showed that the addition of 0.2% sodium hexametaphosphate (SH) provided the best stability for the proanthocyanidins. Extraction time, solid to liquid ratio, microwave power, and ethanol concentration were selected as independent variables, while the extraction yield of PC was taken as response variable. The optimization was carried out based on Box-Behnken experimental design by investigating the individual and combined effects of the four factors on the response variable. The optimum extraction conditions were determined as follows: extracting time, 70 s; material to liquid ratio, 1:20 (g/mL); microwave power, 360 W; and ethanol concentration, 60%. Under these conditions, the PC yield in one extraction cycle obtained was 72.58% with a relative error of 1.12% as compared with the model prediction of 73.46% indicating that these parameters are reliable. In first three cycles, 93.19% of the measured PC were extracted.关键词
