【Abstract】 [Objective] To optimize the conditions of the extracting process of Hujin Granules. [Methods] The orthogonal design was applied. With the total emodin and the total anthraquinone (TA) content as the parameters for the alcohol-extraction, the concentration of alcohol, the volume of solvent and the extracting time were used for optimization of alcohol-extraction. With the total polysaccharide (TP) as the parameters for water-extraction, the soaking time, the volume of water and the extracting time were used for optimization of water-extraction. [Results] The optimum conditions of alcohol-extraction were: extracting with 70% alcohol 245 mL for 2 hours and extracting twice. The optimum conditions of water-extraction were: extracting with 80 mL water (not for soaking) for 1.5 hours, extracting 3 times. [Conclusion] The results indicate that the extracting process is rational and feasible, and can provide evidence for the extracting process of Hujin Granules.更多还原
