闪式提取赤芍总苷的工艺研究

Study on the Tissue-smashing Extraction Process of Total Paeony Glycoside

摘要:

以总苷提取量为评价指标，采用闪式提取器提取赤芍总苷，并利用正交试验法对影响赤芍总苷提取量的因素进行条件优化。结果显示，闪式提取赤芍总苷的最佳提取工艺为：液料比30:1（以水为提取溶剂），浸泡6 h，提取电压为70 V，提取时间2 min，在此条件下经过3次提取所得赤芍总苷的平均提取率为4.84%。

Abstract:

Total paeony glycoside was extracted by tissue-smashing extraction and the extraction conditions were optimized by orthogonal test using the content of total paeony glycoside as main indices. The results showed that the optimum extraction conditions were as follows: liquid-solid ratio 30:1, soaking time 6 h, extraction time 2 minutes and extraction voltage 70 V, under which the total paeony glycoside yield was up to 4.84%.
