| 中文摘要: |
| 目的:对丰城鸡血藤有效成分芒柄花素的提取工艺进行研究。方法：采用HPLC法测定不同提取工艺及纯化工艺中芒柄花素含量，计算提取率。结果：芒柄花素的稀醇提取率大于水提取率，但是稀醇提取物复溶性差，产生大量黑色胶状、絮状及焦屑样的沉淀物；提取液滤去沉淀物后，其保留率小于纯化后的水提取物。 结论：芒柄花素的稀醇溶解度大于水溶解度。药材可以采用稀醇提取。但是醇提取物纯化后和水提取结果相似。 |

| Objective:To study the extraction and purification processes of Formononetin in Millettla nitida var hirsutissima Z wei.Method:HPLC was used to determinate the consent of Formononetin in different extractions or purified extractions,by which the best method was chosen.Result:The extraction rate of Formononetin in water-alcohol was bigger than that in water,But the re-solubility of the former were not good with a large number of dark Jelly,flocculation and black Coke crumbs kind of sediments and had almost the same retention rate as that of the latter after filtered sediments.Conclusion:The dissolution of Formononetin in water-alcohol was bigger than that in pure water,the herb can use water-alcohol as its extraction solvent but with the same purified rate as that of water. |
