摘要
Abstract
Effect of various factors in an ultrasound-assisted process on the polysaccharide extraction from Polygonatum filipes were studied for the technology optimization.The liquid/material ratio,temperature,as well as power and duration of ultrasonic application for the process were scrutinized.A quadratic regression rotational combinational design and the Design Expert 7.0 analytical procedures were applied to establish a regression model for projecting the maximal extraction yield under optimized conditions.Theoretically,the optimized process included the application of a liquid/material ratio of 1 7.81 mL/1 g at 72.97℃ with a 1 52.85 W ultrasonic treatment for 59.74 min to reach 1 6.6471% yield on polysaccharides.In a triplicated test run,an averaged polysaccharide yield of 1 6.59% was obtained with a liquid/material ratio of 18 mL/1 g at 73℃ with a 1 50 W ultrasonic treatment for 60 min.The result showed that the mathematic model was accurate in predicting the performance of the extraction process.关键词
