Table 2 Fragmentation data for two synthesized standards, prenyl crotonate and prenyl butyrate, each with data from a matching peak from a cone sample. The equivalent data for sample peak "*" (Fig. 5b) are also presented, to show the similarity to prenyl crotonate, especially, m/z 67, 68, 69, and likely molecular ion at 154. Dash () indicates 0 or <0.1% relative abundance.
