研究了昆明山海棠和苦皮藤的红外光谱。结果表明，两种中草药的主要成分草酸钙和甜蜜醇的比例不同，吸收频率和吸收形式也不同。此外，南蛇藤茎和根之间存在明显差异，根的FTIR谱图中草酸钙和苦皮酚的峰形均比茎中的峰更尖锐和更强。因此，FTIR可以作为一种快速、可靠的方法来鉴别THH和南蛇藤。
The FTIR spectra of Tripterygium hypoglaucum Hutch (THH) and Celastrus orbiculatus Thunb were studied. The result shows that the two herbs have different ratio of main substance calcium oxalate and dulcitol, so their absorption frequency and form are different as well. In addition, there is an obvious difference between Celastrus orbiculatus stem and root, and both the peak forms of calcium oxalate and dulcitol in the FTIR spectra of roots are sharper and stronger than those of stems. Therefore FTIR can be a fast and reliable method to identify THH and Celastrus orbiculatus.
