摘要：

Trimethylsilyl derivatives of flavanone aglycones give double peaks in their gas chromatograms. The origin of these peaks, from an isomerization between the flavanones and their corresponding chalcones, has been examined using gas chromatography-mass spectrometry and UV spectrophotometry. The effects of derivatization temperature, time and capillary column injection technique on the rate of the interconversion have been defined.
