Optimization of Extraction Process of Anthraquinone Compounds in Sickle Senna Seed
Objective:To optimize the extraction process of anthraquinones from Sickle Senna seed.Methods:Taking the extraction rate of total anthraquinone in Sickle Senna seed as the index,the effects of ethanol volume fraction,extraction time,solid-liquid ratio and extraction temperature are investigated by single factor experiment and L9(34)orthogonal experiment.Results:The optimal process is as follows:ethanol volume fraction of 70％,extraction time of 2.0 h,solid-liquid ratio of 1 to 30(g to mL),and extraction temperature of 85 ℃.Under these conditions,the extraction rate of total anthraquinone from Sickle Senna seed is 4.79％.Conclusion:The extraction process optimized by orthogonal experiments has high extraction rate and stable process,which provides a reference for the industrial production of anthraquinones in Sickle Senna seed.
