GC-MS analysis of diterpenes from hexane extracts of whole petiolules.

<p>(<b>A</b>) Non-transformed <i>S</i>. <i>lycopersicum</i>, (<b>B</b>–<b>D</b>) three individual plants of <i>S</i>. <i>lycopersicum</i> transformed with the <i>35S-</i>CPT2 gene construct. Chromatograms of the selected ion of <i>m/z</i> 109 are shown here. (<b>E</b>) Four combined chromatographs of authentic standards. 1, nerylnerol; 2, lycosantalene: 3, epoxy-lycosantalene; 4, lycosantalonol. Mass Spectra for all peaks is shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0119302#pone.0119302.s002" target="_blank">S2 Fig.</a> Whole petiolules were ground and extracted with hexane as described in Materials and Methods.
