摘要: 为了将熊果酸的纯度自25%提取纯化到98%以上,以熊果酸提取率及其纯度为评价指标,综合考虑乙醇体积分数、溶解温度、料液比及料炭比(原料质量与活性炭质量的比值)对熊果酸提取纯化的影响,并对其提取纯化工艺进行优化。结果表明:熊果酸纯化的最佳工艺条件为乙醇体积分数95%、提取温度80℃、料液比1:20(g/mL)、料炭比2:1,在此条件下熊果酸的提取率为45.68%,纯度达98.55%。

Abstract: In order to improve the purity of ursolic acid, the extraction and purification process of uroslic acid was optimized to explore the effects of ethanol concentration, extraction temperature, material/liquid ratio and material/activated carbon ratio on extraction rate and purity. The results showed that the optimal extraction and purification process conditions were ethanol concentration of 95%, extraction temperature of 80 ℃, material/liquid ratio of 1:20 and material/activated carbon ratio of 2:1. Under the optimal conditions, the extraction rate and purity of uroslic acid were 45.68% and 98.55%, respectively.
