摘　　要：研究微波法提取枸杞叶中甜菜碱的最佳工艺,考察工艺参数对枸杞叶中甜菜碱提取率的影响。以甜菜碱提取率为指标,通过L9(34)正交实验与方差分析优选出枸杞叶中甜菜碱最佳提取工艺条件。结果表明,最佳工艺为固液比为(g:ml)1:10,20 min,微波功率200 w。枸杞叶中甜菜碱最佳提取率平均值可高达4.48%。该工艺简单、稳定、可行。The optimum microwave extraction technology of betaine from Lycium barbarum leaves was studied and the impacts of every technology parameter on extraction rate of betaine were investigated.Extraction rate of betaine was taken as index.L9（34） orthogonal design and analysis of variance were adopted to optimize the technological conditions of microwave extraction of betaine.The results showed that the rate of solid and liquid,extraction time and microwave power were 1：10（g：ml）,20min,200w,respectively,and the average of betaine extraction rate was up to 4.48%.The technology was simple,stable and feasible.
