摘　　要：利用傅里叶变换红外光谱仪测定了蕨和凤尾蕨的叶、茎和根的红外光谱图,分析比较了两个样品的叶、茎和根在红外光谱图上的差异程度,结果表明,尽管它们的药效均有清热利湿,消肿解毒等功效,但由于它们所含的化学成分不同和相对含量的差异,其红外光谱的吸收峰的位置和强度均有不同。通过对红外光谱图的主要特征峰的峰位、峰强的分析,推断出它们可能含有氨基酸、淀粉、少量鞣质等物质,由相应吸收峰的强度比推断出它们的叶均含有大量氨基酸、它们的根富含淀粉。此结果,对常用药用蕨类植物开发利用提供了科学的依据。The IR spectra of leaf,stem and root of eagle-fern and nervous brake were determined and analyzed. The results showed that different chemical component and content composition between them the position and intensity of the absorbance peak varied, due to the. We concluded that eaglefern and nervous brake may contain amino acid,starch and a small of other substances through the above analysis, and there were a lots of amino acid, starch in leaf and root respectively. The results provided some scientific basis for the development of common kinds of medicine fern.
