多指标试验公式评分法优选驱虫斑鸠菊的提取工艺

Study on Extraction Techniques for Vernonia Anthelmintica (L.) Willd. by Multi-index Test Experiment Formula Evaluation

目的:优选驱虫斑鸠菊的最佳提取工艺。方法:应用多指标试验公式评分法结合正交试验设计,以紫铆素含量、总黄酮含量及浸膏得率为指标,考察提取工艺条件。结果:驱虫斑鸠菊的最佳提取工艺为加入10倍量水,浸泡1h,煎煮1h,共3次。结论:所选工艺条件具有科学、简单、实用的特点。

Objective： To optimize the extraction techniques for Vernonia Anthelmintica （L） Wiild. Methods： The extraction techniques was optimized by multi - index test experiment formula evaluation and orthogonal design, which took the contents of butin and total flavonoids and the extraction rate as indices. Results： The optimum extracting procedure was using 10 times volume of water for each time, marinating one hour and then boiling for three times sustaining one hour each. Conclusion： It is scientific, simple and applied.
