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,考察料液比、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45 min。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 orthogonal test was used to study the effects of the factors such as material-liquid ratio, ethanol concentration, extraction time and extraction temperature on the extraction rate of free anthraquinone in sheep’s hoof . Results: The optimum extraction process was 25 times the volume of 90% (volume fraction) of ethanol, 80 ℃ water bath under the leaching two times, each 45 min. Conclusion: The optimized process is stable and reproducible, which provides an experimental basis for the extraction of free anthraquinone from.
