苦杏仁中苦杏仁苷的闪式提取工艺研究

Smashing Extraction for Extracting Amygdalin form Semen Armeniacae Amarum

目的:研究闪式提取法从苦杏仁中提取苦杏仁苷的最佳工艺。方法:采用单因素试验和L9(34)正交试验设计,以苦杏仁苷为指标,对闪式提取的影响因素进行考察,并与文献报道的方法进行比较。结果:闪式提取法的最佳工艺是70%乙醇,提取时间1 min,料液比1∶6。结论:此工艺简单、高效、节能,提取率高,有利于苦杏仁苷的提取。

Objective： To study the optimal technology conditions of smashing extraction for extracting amygdalin form Semen Armeniacae Amarum. Methods： The influence factors on the smashing extraction were investigated by single-factor experiment and L9（34） orthogonal design taking the extraction rate of amygdalin as the index. And smashing extraction were compared with other methods reported in literature. Results： The optimal technique of the smashing extraction was as follows：70% ethanol was taken as solvent,the ratio of material and liquid was 1： 6,extracting time was 1 minute. Conclusion： The extraction process is simple, efficient, energy saving and with high extraction rate, which is beneficial to the extraction of amygdalin.
