5、cosides from Platycodi Radix are not currently available.Objective To develop an efficient method for the preparative separation of six platycosides from Platycodi Radix by high speed counter-current chromatography(HSCCC)coupled with an evaporative light scattering detection(ELSD)system.Methodology
6、Preparative separation was performed by water extraction using reversed-phase C18 column chromatography on an HSCCC-ELSD system.A two-phase solvent system comprised hexanen-butanolwater(1:40:20,v/v)and(1:10:5,v/v)was employed.Two other key parameters,revolution speed of the separation column and flo
7、w-rate of the mobile phase,were also investigated for optimum HSCCC performance.Each peak fraction obtained from separation of the platycosides was collected according to the ELSD elution profile and determined by HPLC.Results Using the described method,six platycosides,all with purities of over 94%
8、,could be isolated from 300mg of the platycoside-enriched fraction.Their structures were characterized by electrospray ionisation mass spectrometry(ESI-MS),1HNMR and 13C-NMR.第十五张,PPT共四十页,创作于2022年6月IntroductionExperimentalApparatus.Reagents and materials.Preparation of crude sample.Measurement of par
