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）。
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).
