摘要
为建立一阶导数紫外光谱法鉴别芒果叶和扁桃叶的方法,制备芒果叶和扁桃叶的水、无水乙醇、石油醚和三氯甲烷的浸提液,检测并比对浸提液的一阶导数紫外光谱数据。结果显示:芒果叶和扁桃叶浸提液的一阶导数紫外光谱的峰位置和吸收强度有明显差异,比常规紫外谱线组法更易识别,可以达到简便、快速鉴别的效果。
In order to establish the method to use first -order derivative ultraviolet spectroscopy to identify mango leaf and almond leaf , the water of mango leaf and almond leaf and the leach liquor of the absolute ethyl alcohol , petroleum ether and trichloromethane were prepared , and the first-order derivative ultraviolet spectroscopy data of leach liquor was tested and compared.The result showed that the peak position and absorption strength of the mango leaf＇s first -order derivative ultraviolet spectroscopy was significantly different from that of almond leaf , which was easier to be identified than the common method of ultraviolet absorption spectra lines group , which can generate the effects of easy and fast identification.
