响应面法优化长柄扁桃中苦杏仁苷的提取工艺

Optimization extracting process of amygdalin from Amygdalus pedunculatus pall by response surface analysis

摘要: 为了综合利用长柄扁桃,提高利用价值,本实验通过响应面实验设计,以苦杏仁苷提取率为响应值,对长柄扁桃中苦杏仁苷的提取参数进行优化。优化后的最佳工艺条件为:乙醇浓度90%,料液比1∶6g/mL,提取时间55min,苦杏仁苷的提取率为提取率为86.91%。

Abstract: In order to optimize the extraction of amygdalin from Amygdalus pedunculatus pall to improve its value, the effects of operation parameters were discussed in this research. The response surface methodology was used to optimize influence of these three factors to the extraction. It indicated that the optimum conditions were as follows:the ethanol concentration of 90%, solid-liquid ratio 1∶6g/mL, extraction time 55min, the extraction percentage was 86.91%.
