离心薄层层析法较经典柱层析法分离周期短,效果好,不仅可节省溶剂、固定相,尤其可节省大量时间。这种方法对小量纯品需求者是有效的分离提纯手段。 已知三七皂甙主要成分与人参皂甙相同。人参叶总皂甙的离心薄层层析分离已有报导,作者用含Na_2C_2O_4固定相的分配层析板分离三七皂甙,对梯度洗脱作了较深入研究,取得较好效果。 Centrifugal thin-layer chromatography than classical column chromatography separation cycle is short, good effect, not only can save solvent, stationary phase, in particular, can save a lot of time. This method is a small amount of pure demand is an effective means of separation and purification. The main components of Panax notoginseng saponins are the same as ginsenosides. Centrifugal thin-layer chromatography of ginseng leaf saponin has been reported. The authors isolated notoginsenosides from the distribution chromatographic plate containing Na_2C_2O_4 stationary phase, and studied the gradient elution.
