【摘要】 [Objective]To explore the infrared spectra characteristics of the medicine Stemona tuberosa Lour.and lay a theoretical foundation for its medicine quality assessment.[Methods]A test of Stemona tuberosa produced in 10 different places of Guangxi Province was conducted by means of infrared spectrometry,and the similarity of the samples were detected by comparing them with a standard spectrogram(this standard spectrogram was set to be 1),which was actually the average spectrogram of each sample.[Results]The infrared characteristic absorption peaks of Stemona tuberosa were acquired.It was shown from the results that the similarity of the 10 samples varied in a range of 0.925 2 to0.980 4,thus the threshold value was settled as 0.90.[Conclusions]This method has a good repeatability and stability.Since this method is of convenience,celerity and dexterity,it can be used as a qualitative testing method for Stemona tuberosa.
