摘　　要：目的建立太白洋参的紫外光谱鉴别方法。方法采用紫外分光光度计研究太白洋参的水、无水乙醇、氯仿和石油醚（60～90℃）4种溶剂的浸泡液的紫外吸收图谱，采用紫外谱线组的吸收峰数及峰位置对其结构特征进行了分析鉴别。结果不同采收季节太白洋参的紫外谱线组的最大吸收峰数目及峰位值基本相同。结论该法简便、准确、灵敏，可为太白洋参的鉴别提供参考。Objective To establish a method for distinguishing Pedicularis decora Franch. Methods UV spectrophotometry was used, Results The UV spectra of the samples gave similar maximum absorption peaks both in number and intensity, which were gathered in different seasons. Conclusion The method is simple and accurate, It can be used to distinguish Pedicularis decora Franch.
