Optimizing Procyanidins Extraction from Lotus Seed Pot with Response Surface Methodology
摘要
Abstract
On the basis of single-factor test, the response surface methodology(RSM) with 4 factors and 3 levels was adopted to optimize ethanol extraction technology of procyanidins from Lotus Seed Pot( LSPC). The interactive effects of the parameters on LSPC yield were investigated. Design Expert 7.1. 6 software was used to fit experimental data and a quadratic polynomial regression model was developed for LSPC yield as a response to the parameters. Results showed that the optimal value of extraction conditions were as follows: ethanol concentration 50% , solvent/material ratio 25 mL/g, extraction temperature 551 and extraction time 60 min. Under such conditions and extraction 1 time, the yield of LSPC was up to 6. 678 mg/100 g, which is close to the predictive yield(6. 693 mg/100 g). This model is reasonable and reliable, and can be used in the actual forecast.关键词
