对填料颗粒的尺寸和不同装填方法,即干法和匀浆法填充的半制备柱的柱效和分离效果进行了研究,并应用于中草药的分离。实验结果表明,粒径小的填料装填的柱效及其分离效果要远远优于粒径大的,匀浆法装填的分离结果好于干法且重现性好;对于芍药和银杏提取物使用自装填半制备色谱柱进行分离,可以得到满意的分离结果。
The effects of packing particle size and packing method, ie, the efficiency and separation efficiency of semi-preparative columns packed with dry and homogenized methods, were investigated and applied to the separation of Chinese herbal medicines. The experimental results show that the packing efficiency of the small particle packing is much better than that of the large particle size packing. The separation result of the homogenization method is better than that of the dry method and the reproducibility is good. For the peony and Ginkgo biloba extract Use self-loading semi-preparative column for separation, you can get satisfactory separation results.
