为建立南五味子快速鉴别方法,用粉末直接压片法测定南五味子、五味子对照药材、市售药材及2种自采样品粉末的红外光谱,利用软件绘制红外光谱并进行分析比较,计算400~4 000 cm-1范围内不同区域的红外光谱的相似性、观察吸收峰数量及峰形。结果表明,南五味子固体粉末在500~900 cm-1处的红外光谱相似性和1 000~1 700 cm -1处的峰形、峰高比、峰数量可作为其鉴别依据。

[Abstract]
The rapid identification method of Fructus schisandra sphenantherae was explored by infrared spectroscopy. Select the reference material of Schisandrae sphenantherae, Schisandrae chinensis, Fructus schisandrae sphenantherae bought from the market and 2 kinds of sample gathered from Liangdang county as experimental materials. The infrared spectrometry of these samples were tested and recorded by tableting method, and the infrared spectra of each sample were drawn by software. The similarity of infrared spectra in different regions within the range of 400~4 000 cm-1 and the number and shape of absorption peaks were calculated. The results indicated that the infrared spectral similarity of Fructus schisandrae sphenantherae powders at 500~900 cm-1 and the peak shape, peak height ratio and numbers of solid powder at 1 000~1 700 cm-1 could be used as the identification basis.
