Jiaogulan (Gynostemma pentaphyllum; GP) contained a saponin glycoside which was related to ginseng saponin. The purpose of this study was to identify the main saponin in water extract GP compared to methanol and ethanol extract. The sample was prepared by alkaline cleavage, trimethylsilyl (TMS) derivatization and gas chromatographic-mass spectrometric (GC-MS) analysis comparison with standard ginsenoside Rb1. The results showed that there were two main dammarant type aglycones in water… Expand

Saponin: Properties, Methods of Evaluation and Applications
Saponins are secondary metabolites with high molecular weight. They present in a wide range of plant species and are distributed throughout the bark, leaves, stems, roots and even flowers. SaponinsExpand


Analysis of ginsenosides by chromatography and mass spectrometry: release of 20 S-protopanaxadiol and 20 S-protopanaxatriol for quantitation.
To facilitate studies on the possible presence of ginseng products in serum, tissues, and excretions, a procedure to optimize the analysis of the gINSeng specific products, i.e., ginsenosides, had to be worked out by using an improved alkaline cleavage procedure. Expand
