| 中文摘要:目的 优选延龄草总皂苷提取纯化工艺，并对其纯化前后的抗炎活性进行对比。方法 以延龄草总皂苷提取率为考察指标，采用正交试验优化提取工艺；应用大孔吸附树脂技术，通过静、动态吸附和解吸附实验，确定最佳纯化工艺；为了证实工艺的合理性，对纯化后的总皂苷抗炎活性进行验证。结果 最佳提取工艺为乙醇体积分数75%，料液比1∶10，加热回流提取2次，每次1.5 h。纯化工艺为HPD400大孔树脂，以质量浓度为0.1 g·mL–1的药液上样，上样量为折合生药（g）∶树脂（mL）=1∶2，以1 BV·h–1流速上样，然后依次以水2 BV、20%乙醇水3 BV洗脱除杂，收集70%乙醇水洗脱液（5 BV），经浓缩、干燥即得延龄草总皂苷收率为7.42%，总皂苷质量分数为34.29%。该总皂苷在质量浓度为5.00、1.00 μg·mL–1时对脂多糖诱导RAW264.7细胞释放一氧化氮有明显的抑制作用，其半数抑制浓度（IC50）值为3.79 μg·mL–1，而其醇提物的IC50值为20.68 μg·mL–1，说明精制过程实现了药效成分的富集。结论 该提取纯化工艺稳定、可行，所得到的延龄草总皂苷与其醇提物相比具有更好的抗炎活性。 |

| Abstract:Objective To optimize the extraction and purification of total saponin from Trillium tschonoskii Maxim. and compare its anti-inflammatory activities before and after purification.Methods The extraction rate of total saponin was used as the index to optimize the extraction process by the orthogonal test. The optimized purification process was determined by static and dynamic adsorption and desorption tests by macroporous adsorption resin technology. The anti-inflammatory activity of purified total saponin was tested to verify the rationality of the purification process.Results The optimal extraction conditions were obtained as follows: ethanol volume fraction of 70%, the solid-to-liquid ratio of 1:10, and extraction twice by heating reflux, 1.5 h for each time. The optimized purification process was obtained. To be specific, 0.1 g·mL–1 sample solution was loaded on the HPD400 macroporous adsorption resin with the loading volume of the crude drug (g):resin (mL) of 1:2 at the flow rate of 1 BV·h–1, followed by elution and purification with 2 BV of water and 3 BV of 20% ethanol in sequence. The 70% ethanol eluate (5 BV) was collected, concentrated, and dried to obtain the total saponin of T. tschonoskii at a yield of 7.42%. The mass fraction of total saponin was 34.29%. The total saponin showed a significant inhibitory effect on LPS-induced nitric oxide (NO) release from RAW264.7 cells at mass concentrations of 5.00 and 1.00 μg·mL–1, with an IC50 value of 3.79 μg·mL–1. The IC50 value of its ethanol extract was 20.68 μg·mL–1, indicating that the purification process achieved the enrichment of medicinal components.Conclusion The extraction and purification process was stable and feasible, and the obtained total saponin of T. tschonoskii possessed superior anti-inflammatory activity to the ethanol extract. |
