Fig. 1.

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. aurantium (albedo and flavedo), lane 5=C. deliciosa (pericarp), lanes 6 and 7=C. limon ‘Interdonato’ (flavedo and albedo), lanes 8 and 9=C. limon ‘Kara Limon’ (flavedo and albedo), lanes 10 and 11=C. limon ‘Cyprus’ (flavedo and albedo), lanes 12 and 13=C. maxima (flavedo and albedo), lanes 14 and 15=C. maxima. Volume of each sample was 10 µL, except in lane 15 (15 µL)
