Caption: Figure 1: A typical HPLC chromatograph showing the standard mixture of phenolic compounds, i.e., [1] caffeic acid, [2] resorcinol, [6] vanillic acid, [7] p-coumaric acid, [9] ferulic acid, [10] vanillin, [11]
veratric acid, [4] myristicin, [5] coumarin, and cinnamic acid.
In addition, only for the groundwater filtered from wells H4-1, 3 bottles were prepared with 70 mg of either [sup.13]C-labelled
veratric acid (Sigma-Aldrich, USA) or unlabelled ([sup.12]C)
veratric acid (Sigma-Aldrich, USA).
The characteristic UV-vis absorption peaks of veratryl alcohol, veratraldehyde, and
veratric acid appear at 277 nm, 308 nm, and 252 nm, respectively (Fig.
