摘要
目的:研究大黄中总蒽醌提取工艺。方法:以大黄素含量为考察指标,采用L9(34)正交试验法进行筛选。结果:乙醇浓度、乙醇用量、浸润时间三因素对大黄总蒽醌的提取有显著影响。结论:最佳提取工艺为:大黄用8倍量55%乙醇按渗漉法提取,浸泡12h,渗漉9h。大黄素含量≥2.6%。
Objective:To optimize the extraction of the total anthraquinone of rhubarb. Methods:Taking content of emodin as parameters. The optimum extraction process was selected with the L9(34) orthogonal design. Results:The significant effects of alcohol concentration, alcohol volume and percolation time on the extraction of emodin content were discovered. Conclusion:The optimum rhubarb percolation condition obtained was:adding 8-fold times of 55% alcohol and percolating for 9 hours. Emodin content ≥2.60%.
