Gas chromatography/mass spectrometry (GC/MS), with an ion trap mass analyzer, was used to examine the very‐long‐chain cuticular acid and certain non‐acid wax constituents on the leaf sheath surface of Sorghum bicolor before and during 36 hours of light exposure. The mass spectra of the trimethylsilylated acids and alcohols did not match any of those published in searchable mass spectral libraries. The observed differences can be related to the interaction between water and the trimethylsilylated acids and alcohols. Understanding the observed mass spectra of the very‐long‐chain plant waxes is critical for studies that employ GC/MS with the ion trap mass analyzer to elucidate cuticular wax compositions on plants.
