目的:优选羊蹄中游离蒽醌的最佳提取工艺。方法:在单因素试验的基础上,以游离蒽醌提取率为指标,采用正交试验方法,考察液固比、乙醇浓度、提取时间、提取温度等因素对羊蹄中游离蒽醌提取率的影响。结果:最佳提取工艺为25倍量的90%(体积分数)乙醇,80℃水浴下浸提2次,每次45min。结论:优选出的工艺稳定,重复性好,为提取羊蹄中游离蒽醌成分提供了实验依据。
Objective: To optimize the extraction process of free anthraquinone in sheep’s hoof. Methods: Based on the single factor test, the extraction rate of free anthraquinone was taken as an index. The effects of liquid-solid ratio, ethanol concentration, extraction time and extraction temperature on the extraction rate of free anthraquinone in sheep’s hoof were investigated by orthogonal test . Results: The optimum extraction process was 25 times volume of 90% (volume fraction) ethanol, 80 ℃ water bath for 2 times, each time 45min. Conclusion: The optimized process is stable and reproducible, which provides an experimental basis for the extraction of free anthraquinone from.
