n.洗提液

Eluant:a substance used as a solvent in the process of elution. 洗提液:在洗提過程中作為溶劑的物質(zhì).

Analytes in eluant were determined using GC equipped with FPD and external standard method. 以GC-FPD測定，外標法定量，測定結(jié)果用不同極性的毛細管柱驗證。

The mixture of ammonia and NaCl was chosen as an optimal eluant, the elution yield was 77.42%. 在此基礎(chǔ)上

In order to have a high elution rate, the ethanol with the concentration of 70% could be used as eluant. 隨著乙醇濃度的增加，洗脫的效果趨好，為了得到高的洗脫率，選用濃度70%25的乙醇作為洗脫劑；

RESULTS:The elution ratio of the portion of Achyranthes Bidentata Saponins that enriched in 50% alcohol eluant was above 58.42%. 結(jié)果牛膝總皂苷富集于50%25乙醇洗脫液部分
