摘要
目的 :研究蒲黄中总黄酮的提取工艺。方法 :采用正交试验法进行优选 ,紫外分光光度法测定总黄酮含量。结果 :乙醇浓度、提取时间、提取次数对蒲黄总黄酮的提取有非常显著性或显著性影响。结论 :最佳提取工艺为蒲黄用 70 %乙醇提取 3次 ,溶剂用量依次为 8,6 ,6倍 ,提取时间为 6 0 ,6 0 ,30min。
Objective: To study the extraction process of the total flavones of Pollen Typhae ( Typha angustifolia L.). Methods: The optimum extraction process was selected with the orthogonal design. The content of total flavones was determined by UV spectrophotometry. Results: The significant effects of alcohol concentration, extraction time and extraction times on the extraction of total flavones were discovered. Conclusion: The optimum extraction process was as follows: Pollen Typhae was extracted with 70% alcohol for 3 times, with the solvent volume 8, 6, 6 times amount and extraction time 60, 60, 30 minutes in turn.
