n.洗提液
Eluant:a substance used as a solvent in the process of elution. 洗提液:在洗提过程中作为溶剂的物质.
Analytes in eluant were determined using GC equipped with FPD and external standard method. 以GC-FPD测定，外标法定量，测定结果用不同极性的毛细管柱验证。
The mixture of ammonia and NaCl was chosen as an optimal eluant, the elution yield was 77.42%. 在此基础上
In order to have a high elution rate, the ethanol with the concentration of 70% could be used as eluant. 随着乙醇浓度的增加，洗脱的效果趋好，为了得到高的洗脱率，选用浓度70%25的乙醇作为洗脱剂；
RESULTS:The elution ratio of the portion of Achyranthes Bidentata Saponins that enriched in 50% alcohol eluant was above 58.42%. 结果牛膝总皂苷富集于50%25乙醇洗脱液部分
