夹板式制备薄层层析是在干柱层析和制备型薄层层析基础上产生的一种色谱分离新技术,具有分离效果好、操作简便、省时、溶剂用量少、上样量大、色带易收集等特点。本文报道应用国产 ZB—Ⅱ型夹板式制备薄层层析仪对苦瓜中葫芦苦素类化合物进行制备性分离的结果。
Splint preparation TLC is a new chromatographic separation technology based on dry column chromatography and preparative thin layer chromatography. It has good separation effect, easy operation, time-saving, low solvent consumption and sample volume. Large, easy to collect and other features. This paper reports the results of preparative separation of cucurbitin compounds from bitter gourd using domestic ZB-II plywood preparation thin-layer chromatography.
