胶陀螺多糖超声提取工艺优化

以多糖提取率为指标,采用单因素和正交试验,优化了超声波提取胶陀螺(Bulgaria inguinans)子实体多糖的提取工艺.结果表明:超声提取胶陀螺多糖的最佳工艺为提取时间35 min、提取温度50℃、液料比20∶1(mL∶g),在此条件下多糖的提取率为4.71％.

Optimization of Selected Parameters Affecting the Ultrasonic Extraction of Polysaccharide from Bulgaria inquinans

Selected parameters (treatment time,extraction temperature,solvent to fruit body ratio) affecting the yield of polysaccharide extracted from Bulgaria inguinans fruit bodies using ultrasound were initially optimized by single factorial experiments.Application of orthogonal testing predicted the optimal extraction conditions to be 35 minutes extraction time,50 ℃ extraction temperature and a solvent to fruit body ratio of 20∶1 (mL∶g).Under these conditions,the yield of polysaccharide obtained was 4.71％.
