Detection by spraying with vanillin-sulfuric acid reagent. Quantitative determination by absorbance measurement at 595 nm. Intra-day and inter-day precision were evaluated by replicate (n = 6) analysis of samples (trans-citral at 450, 900, and 1800 ng/band, and cis-citral at 470, 940, and 1880 ng/band). The linear range was 225-3600 ng/band for trans-citral, and 470-3760 ng/band for cis-citral. The correlation coefficient r was 0.9933 for trans-citral and 0.9937 for cis-citral. Intra-day precision (n = 6) was < 3.56 and 5.66 % for trans- and cis-citral, respectively. Inter-day precision was assessed to be < 3.47 and 5.52 % for trans- and cis-citral by repeating the intra-day assay on three different days. Repeatability of sample application and peak-area measurement was 0.98 %, determined by performing six replicate analyses of the same band (1800 ng/band trans-citral and 1880 ng/band cis-citral). The RSD of recovery of trans and cis-citral was in the ranges 1.36-3.25 and 1.64-3.47, respectively.
