Table 1 Description of the ikats under investigation and summary of the results obtained by dye analysis. The dates reported are those attribute based on stylistic interpretation, expect for the ikats in which synthetic dyes were found (terminus post quem production dates are reported in bold for these textiles). For HPLC-DAD analysis, the values between paranthesis are percentages resulting from the intergration of the chromatographic areas (254 nm) of all peaks (dye molecules) attributed to the molecular components of the dye source considered. All dye molecules identified for each dye source are discussed in detail in the corresponding sections. The results reported in italic were obtained by additional HPLC-DAD-MS analysis

  1. The dates reported are those attributed based on stylistic interpretation, except for the ikats in which synthetic dyes were found (terminus post quem production dates are reported in bold for these textiles). For HPLC–DAD analysis, the values between parenthesis are percentages resulting from the integration of the chromatographic areas (254 nm) of all peaks (dye molecules) attributed to the molecular components of the dye source considered. All dye molecules identified for each dye source are discussed in detail in the corresponding sections. The results reported in italic were obtained by additional HPLC–DAD-MS analysis
  2. * Percentage values are intended as broad estimations of the extract content for internal comparison, as they do not necessarily correspond to dye concentrations in the threads. In the case of indigo-containing samples, 254 nm is not the best wavelength to detect indigoids, but this wavelength was kept to maintain internal comparability. However, as a result, the absolute values of the indigo percentage are underestimated
  3. ** Samples were taken from different panels
  4. *** Samples were taken from the same panel
