【摘要】 目的 以共有峰率和变异峰率双指标序列法分析不同种千斤拔指纹图谱。方法 采用石油醚、氯仿、95 %乙醇、水等四种溶剂分别提取千斤拔药材不同极性部位成分,测定其紫外、红外指纹图谱,研究各个样品之间的异同。结果 该方法可以区别出不同种千斤拔药材。结论 该方法便于两个及以上样品之间的比较,应用范围广,为千斤拔药材质量评价提供了简便的方法。

【Abstract】 Objective:To analyze the fingerprint spectra of Radix moghaniae by the method of common and variant peak ratio in IR﹑UV and dualindex sequence analysis.Methods:Petroleum ether,chloroform,95%ethanol and water were used to distill Radix moghaniae chemical constituents which are different polarities,and the differences among those samples were determinated by the way of analyzing the fingerprint spectra.Results:The method could distinguish different species of Radix moghaniae.Conclusions:The method is convenient for comparing two or more than two samples,and has a large range of application.At the same time,it provides a simple and convenient method to estimate the quality of Radix moghaniae.
