Fig. 2.

HPTLC profiles of the Citrus extracts: a) image of the derivatized plate with AlCl₃ under UV light at 366 nm, and b) image of the derivatized plate under white light (AlCl₃, then natural product PEG 400). Lane 1=caffeic acid, lane 2=hesperidin, lanes 3 and 4=C. paradisi ‘Handerson’ (flavedo and albedo), lanes 5 and 6=C. paradisi ‘Red Blush’ (flavedo and albedo), lanes 7 and 8=C. paradisi ‘Star Ruby’ (flavedo and albedo), lane 9=C. reticulata ‘Lee’ (pericarp), lane 10=C. reticulata ‘Nova’ (pericarp), lane 11=C. reticulata ‘Blanco’ × C. paradisi (pericarp), lanes 12 and 13=C. sinensis ‘Navelina’ (flavedo and albedo), lanes 14 and 15=C. sinensis ‘Navelina’ (flavedo and albedo). Volume of each sample was 10 µL, except in lanes 14 and 15 (15 µL)
