凹叶景天的生药鉴定研究

Studies on Identification of Sedum emarginatum

目的:对凹叶景天(Sedum emarginatumMigo)进行生药学鉴定研究。方法:利用性状、显微鉴定法及红外光谱法对该药材进行鉴定研究,确立鉴别特征。结果:该品茎的横切面与全草粉末显微特征明显,且不同产地及不同采收期的药材样品具有相对稳定的红外光谱特征。结论:研究结果可作为凹叶景天药材的鉴定依据。

Objective：To establish methods for identification of the whole plant of Sedum emarginatum Migo.Methods：Macroscopic and microscopic observation and FTIR technique were used to authenticate this crude drug,and the identification characteristics were studied.Results：The stem cross section and the whole plant powder had some notable micro-characters.The infrared spectras of the samples collected in the different habitats and seasons were very consistent with each other.Conclusion：The results can be used as the evidence for identification of this ethnomedicine.
