Paper Chromatographic Determination of Optimum Methods for Extraction of Plant Constituents

Chen Ying-jie   

Abstract: A paper chromatographic method for the determination of suitable conditions for extraction of plant constituents is presented in this paper. The steps taken in the method are as follows: 1. Determining the optimum solvent systems from paper-chromatographic data. 2. Determination of separation method according to the separation factor β. 3. Determining the suitable volumes of solvents from the volume ratio R. 4. Calculating transfer number N for counter current distribution. It was used in determining the optimum procedure for the separation of hyoscyamine, scopolamine, esculetin, esculin and other natural compounds.
