✦ Synopsis

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.

Photoproducts resulting from illumination of a pyrene-chloroform solution using several light sources (sunlight, lamp, a pulsed laser) were analyzed by using gas chromatography (GC) and GC-mass spectrometry. The main photoproducts in chloroform were chloropyrene and pyrenecarboxaldehydes, and their
