摘要
目的:利用紫外谱线组法测试4种大黄炮制品在不同极性溶剂中的紫外谱线图谱,根据它们的紫外谱线图谱峰位置的差异,对其加以区分鉴别。方法:对生大黄以石油醚、三氯甲烷、无水乙醇及蒸馏水进行超声波提取后,再进行相应的紫外光谱检测,并对获得的紫外谱线组进行分析。结果:大黄紫外谱线组重现性良好,可以用于大黄的不同炮制品的鉴别。结论:通过紫外谱线组法可以区分大黄及其炮制品。
Objective： To determine the ultraviolet spectra of four kinds of processed products of Rheumpalmatum L in different polar solvents by UASLG,and identified them by analysis of the difference of their spectrum peaks. Method：Ultrasonic extraction was used for four kinds of processed products of Rheumpalmatum L. in the different polar solvents including petroleum ether, chloroform, anhydrous alumina,and distilled water in turn,and then their absorbance in UV was determined and the differences of their spectra were detected. Results： The UASLG of the four kinds of processed products of Rheumpalmatum L. was reproducible ,which could be used to identify them. Conclusion ：We can distinguish the difference of the four kinds of processed products of Rheumpalmatum L by the methods of UASLG.
