摘要
比较了卫矛科的昆明山海棠和南蛇藤粉末和醇提物的红外图谱特征。两种药材的粉末图中都看到草酸钙和淀粉的特征。醇提物图中都有卫矛醇的特征,但南蛇藤较为明显。两种药材醇提物的二阶导数图有明显差异,说明某些成分含量不同。南蛇藤根图的草酸钙和卫矛醇的峰形都比茎的强和尖,说明其根中草酸钙和卫矛醇的含量比茎大。由于红外法既能快速地找出药材差异,又能准确指认出卫矛醇,所以此法制定的宏观指纹图谱可作为生药鉴定的依据。
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.
