微波-表面活性剂协同提取金莲花黄酮的研究?

Study on Microwave-surfactant Extraction of Flavone from Trollius Chinensis Bunge

摘要:

研究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)，最后通过正交试验优化了提取工艺。结果表明：最佳工艺条件为：以质量浓度? = 0.75 mg/mL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5min。在此工艺条件下,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%。

Abstract:

Microwave-surfactant Extraction of Flavone from Trollius Chinensis Bunge was studied, choose SDS as significant surfactant, and extraction process was optimized by orthogonal experiment. The results showed that the optimum conditions for extracting was: SDS(?=0.75㎎／ml) as extraction agent, solvent amount of 40 ml／g Trollius Chinensis Bunge， microwave power of 600W, temperature of 70℃,extraction for 5 min. Under this condition, extraction rate can be up to 5.35%. Compared with traditional solvent, extraction time was decreased greatly, and extraction rate was increased about 30%.
