摘要
为了进一步对沙柳、柠条液化产物组分结构的研究,本文利用薄层色谱和柱层析结合的方法分别对沙柳、柠条液化产物进行分离。首先根据液化工艺正交试验选择出适宜的沙柳、柠条各自的液化产物;利用薄层色谱法确定了最佳的洗脱溶剂,并分析了不同有机溶剂对液化产物样品在薄层色谱实验中的影响。根据液化样品的极性,选择硅胶作为固定相,洗脱溶剂为石油醚和乙酸乙酯的混合物(2:3,V/V),进行单向一次性柱层析分离。将分离后的各组分溶液重结晶精制浓缩后得到沙柳、柠条液化产物各自较纯的组分。
In order to study on the structures of liquefied resultants of Salix psammophila(S.P) and Caragana intermedia(C.I),the liquefied resultant of S.P and C.I are separated by Thin-layer Chromatogram(TLC) and column chromatography in this paper.The first step the optimal liquefied resultants of S.P and C.I are selected according to the Orthogonal Experiment.The eluent is determined by TLC to analyze the effect of different solvents.The optimal solvent is obtained(the mixture of Petroleum ether and Ethyl acetate(...
