丹皮紫外指纹图谱共有峰率和变异峰率双指标序列分析

目的：采用指纹图谱共有峰率和变异峰率双指标序列分析法分析丹皮类药材紫外指纹图谱。方法：本文用3种溶剂氯仿、无水乙醇及水，系统提取丹皮等不同极性区间成分，测定其紫外指纹图谱，研究样品的异同。结果：该方法可以准确对丹皮类药材进行细致的鉴别。结论：利用共有峰率和变异峰率双指标序列分析法可以对两个或多个样本进行可靠的鉴别。

Sequential Analysis of Double Indexes of Common and Variant Peak Ratios in Ultraviolet Fingerprint of Paeonia Suffruticosa Andr.Root Bark

Objective: To analyze the ultraviolet fingerprint of the root bark of Paeonia Suffruticosa Andr. and other medicinal crops of its kind by the method of sequential analysis of the double indexes of common and variant peak ratios in ultraviolet fingerprint. Method: In this article three solvents-Chloroform, absolute ethel alcohol and water are introduced to systematically extract the components of the root bark of Paeonia Suffruticosa Andr. and other medicinal plants of its kind in different polar zones, examine their ultraviolet fingerprints and study the differences of the samples. Result: This method is able to accurately identify the root bark of Paeonia Suffruticosa Andr. and other medicinal plants of its kind in detail. Conclusion: Tow or several samples can be reliably identified by the method of sequential analysis of the double indexes of common and variaut peak ratios.
