MOESM2 of Application of delayed luminescence measurements for the identification of herbal materials: a step toward rapid quality control

Additional file 2: Figure S1. The differences of DL properties between authentic and sulfur fumigation herbal materials. A1) Angelicae dahuricae radix (sliced materials); A2) Angelicae dahuricae radix (sulphur fumigation sample, sliced materials); A3) DL decay curves. Data are plotted as the mean ± SEM. Note that the data are plotted on a log-log scale; A4) Histograms comparing the DL properties between Angelicae dahuricae radix and its sulphur fumigation sample. Mean ± SD, *, p < 0.05; B1) Codonopsis radix (whole materials); B2) Codonopsis radix (sulphur fumigation sample, whole materials); B3) DL decay curves. Data are plotted as the mean ± SEM. Note that the data are plotted on a log-log scale; B4) Histograms comparing the DL properties between Codonopsis radix and its sulphur fumigation sample. Mean ± SD, *, p < 0.05, ns, no significant difference.
