摘要
建立超声辅助溶剂法提取麻疯树饼粕中的植物甾醇,以分光光度法检测提取物中甾醇含量。采用正交试验设计优选提取工艺,最佳提取工艺为麻疯树饼粕50g,丙酮100mL,超声提取1h。优化工艺条件下植物甾醇的萃取率可达0.347%。
Ultrasonic assisted solvent extraction technique was applied for the extraction of plant sterols from jatropha cake,and the content of plant sterols was determined by spectrophotometry. The extracting conditions optimized by orthogonal experiment were as follows-jatropha cake of 50g, acetone of 100mL, extraction time of lh. Under the optimal conditions, the extraction rate of plant sterols was up to 0. 347 %.
