当归固体发酵后水提取工艺优选

Optimizing Water Extraction Conditions for Solid-fermented Angelica sinensis

摘要:

目的: 优选固体发酵后当归的水提取工艺。 方法: 以阿魏酸、干浸膏为指标,用正交设计优选提取工艺。 结果: 最佳提取工艺为浸泡0.75 h,煎煮2次,1 h/次,加水量为药材的12倍和8倍量。 结论: 确定的提取工艺稳定可行,可作为发酵后当归的提取方法。

Abstract:

Objective: To optimize the water extraction conditions for solid-fermented Angelica sinensis. Method: Orthogonal design was used in optimizing the extraction conditions while ferulic acid and extract dry weight were adopted as markers. Result: Optimum extraction technology was as follows: the medicinal materials were soaked in water for 0.75 hour, and extracted 2 times with one hour for each time by 12-fold and 8-fold volume of water. Conclusion: Extraction technology established in this experiment is stable and feasible and can be used to extract solid-fermented Angelica sinensis.
