IDENTIFICATION CHALLENGES IN EXAMINATION OF COMMERCIAL PLANT
standard solution and 5 µL of prepared mixture (mix) were applied as bands Chromatograms were developed to 4/5 of the plate height, then dried in air, treated with the anisaldehyde solution, heated in 105OC, examined in daylight and photographed with a video-scanner HPLC method HPLC analysis was performed on Luna C18(2)

Tandem Zirconocene Homologation – Aldimine Allylation
Reactions were monitored by TLC analysis (EM Science pre-coated silica gel 60 F 254 plates, 250 µm layer thickness) and visualization was accomplished with a 254 nm UV light and by staining with a PMA solution (5 g of phosphomolybdic acid in 100 mL of 95 EtOH), p-anisaldehyde solution (2 5 mL of p-anisaldehyde, 2 mL of AcOH, and 3 5 mL of
