Optimization of Ultrasonic Extraction Conditions for Polysaccharides from Codonopsis lanceolata and Its Antioxidative Activity
摘要
Abstract
Take Codonopsis lanceolata as test material,based on the single factor experiment,the response surface methodology was employed to optimize the extraction conditions of polysaccharides from Codonopsis lanceolata and its antioxidant activity was primarily evaluated.The results showed that the optimum extraction conditions were as follows:ultrasonic power 138 W,ultrasonic time 14 min,ultrasonic temperature 35℃.Under these conditions,the average extraction yield of CLPS1 was 12.48%.IC50of DPPH·,·OH,ABTS+were (3.04 ±0.35)mg/mL, (2.494±0.4)mg/mL,and (3.41±0.59)mg/mL,respectively,CLPS1 had strong antioxidant activity.关键词
