High-performance Thin Layer Chromatography (HPTLC) of whole apple (Malus domestica cv. Anna) freeze-dried AE powder (1 mg mL−1) (Image Comparison View, CAMAG). The HPTLCs were developed with UV light at 366 nm (1); or derivatized and developed with the natural products reagent and at 366 nm (2); with anisaldehyde at visible light (3); with anisaldehyde at 366 nm (4); with phosphomolybdic acid at visible light (5), with Fast Blue B Salt staining at visible light (6); and with Dragendorff reagent at visible light (7)
