Five dammarane‐type aglycones, released from gypenosides following an alkaline cleavage procedure previously developed for ginsenosides, were separated and characterized by gas chromatography‐mass spectrometry (GC‐MS) after trimethylsilylation. A satisfactory identification among isomers of 20( S )‐protopanaxadiol or 20( S )‐protopanaxatriol was obtained. © 1998 John Wiley & Sons, Ltd.
