摘要
利用索氏回流提取法提取黑胡椒中胡椒碱,以胡椒碱的提取率为考察指标,采用单因素及正交试验优化胡椒总碱的提取工艺,得到最佳提取工艺条件:乙醇作为提取溶剂,溶剂用量(料液比)1 8 g/mL,溶剂浓度90%,物料粒度180目,提取时间5 h.
Extraction of piperine in Pepper alkaloids by Soxhlet reflux extraction method was studied in this article using orthogonal experiment. The effect of every factor on extracting efficiency was investigated applying the extraction rate of Piperine as indicator. The optimal extraction conditions were： ethanol as extraction solvent,the amount of solvent （liquid-solid ratio ）1：8 g/mL, the solvent concentration 90%, 180 mesh of material panicle size, extraction time 5 h.
