Detection Method Saturated chamber; developing distance 70 mm from lower edge; relative humidity 33% Other Notes Images presented in this entry are examples and are not intended to be used as basis for setting specifications for quality control purposes. System suitability test: Rutin: orange fluorescent zone at Rf ~ 0.07; Caffeic acid: light bluish fluorescent zone at Rf ~ 0.77. Identification: Compare result with reference images. The fingerprint of the test solution is similar to that of the corresponding botanical reference sample. Additional weak zones may be present. The chromatogram of the test solution shows a yellow zone at Rf ~ 0.17, a light blue zone at Rf ~ 0.20, a faint yellow zone at Rf ~ 0.26 and a faint blue zone at Rf ~ 0.32. A light blue zone is seen in the center part of the chromatogram at Rf ~ 0.53 (yellow arrow). Test for other species: No intense dark blue zone is seen at Rf ~ 0.78 (white arrow, Bitter Fennel fruit). No light blue zone is seen at Rf ~ 0.62 (red arrow, Anise fruit or Caraway fruit). No brownish zones are seen at Rf ~ 0.32 and 0.38 (green arrows, Caraway fruit).
