摘要
考察了表面活性剂协同微波提取金莲花黄酮的工艺,筛选出了具有明显增效作用的表面活性剂十二烷基硫酸钠(SDS),最后通过正交实验优化了提取工艺.结果表明,最佳工艺条件为:以质量浓度0.75 g/L的表面活性剂SDS水溶液为提取剂,提取溶剂用量为40 mL/g金莲花,微波功率600 W,温度70℃,提取时间5 min.在该工艺条件下,金莲花黄酮的提取率为5.35%.与溶剂浸提法相比,提取时间显著缩短,金莲花黄酮的提取率提高约30%.
The microwave-surfactant extraction of flavone from Trollius Chinensis Bunge was investigated,choosing SDS as the significant surfactant,and the extraction process was optimized by the orthogonal experiment.The results showed that the optimum conditions for extracting was：SDS（ρ（SDS）=0.75 g/L） as the extraction agent,the solvent amount of 40 mL/g Trollius Chinensis Bunge,microwave power of 600 W,temperature of 70 ℃,extraction for 5 min.Under this condition,the extraction rate can be up to 5.35%.Compared with the traditional solvent,the extraction time was shortened significantly,and the extraction rate was increased about 30%.
