中药鉴别导数紫外光谱谱线组法研究

在中药鉴別紫外谱线组法基础上对几十种中药进行了导数紫外光谱谱线组法测试研究,发现其四溶剂一阶导数谱线各异,且具有较好的特征性、重现性和较高灵敏性,直接读数,准确、快速、直观。据此首次提出鉴别中药的导数紫外光谱谱线组法,提高了鉴别中药的可靠性和方法本身的选择性,并且用该法对部分不同产地基原相近及常用中药材进行了测试鉴别,取得了满意效果,为中药鉴別工作提供了一种高灵敏性、快速、简便的现代仪器分析方法。

STUDIES ON GROUP OF DERIVATIVE ULTRAVIOLET ABSORPTION SPECTRA LINES FOR IDENTICATION OF CHINESE METERIA MEDICA

The method on group of derivative,ultraviolet absoption spectra lines was used to determined for forty species of Chinese materia medica in four species of solvent.Their diagrams on group of first order dervative ultraviolet species of solvent,and their characteristic and reappearance and sensitivity are all better than the old method.This method is rapid and accurate,and data were directly perceived through the senses.The first order derivative ultraviolet spectrograms have been determined for some Chinese mataria medica are similar in gene.A method of modernized instrument analyse of highly sensitivity and high- speed and handy for identification of Chinese materia mediea was provided.
