摘 要 ：目的：为了更好地控制麦冬的质量。方法：用ＴＬＣ法比较了来源于麦冬和山麦冬属植物药材的差异，用分光光度法定量测定了１０批样品总皂甙的含量。结果：不同来源地和不同等级的麦冬总皂甙含量有较大差异。结论：该方法简单、快速，且样品的醇提物可以不提前处理，直接与高氯酸反应测定，ＲＳＤ＝０．７５％（ｎ＝５）。

Abstract:Objective: To explore a better approach to controling the quality of Maidong. Method: The differences between Ophiopogon japonicus and the plants belonging to Liriope genus were identified by TLC.The total saponins in plants collected from different areas were determind by spectrophotometry,using HClO₄ as the staining agent. Results: The quantity of Maidong markedly varies with producing areas. Conclusion: This method is convenient and effective,and the MeOH extract of samples can be determined directly after reaction with HCIO₄ without preliminary treatment.The RSD was 0.75%(n=5).
