Abstract

The earlier TLC method [see FSTA (1974) 6 2T99] for detection of capsaicin in ginger extracts is not suitable if colourless pungent capsaicin or capsicum extract are used for adulteration after decoloration. This is overcome by a TLC procedure using (i) benzene/methanol (80:5) and (ii) hexane/ether (1:1.5) as solvent systems and Gibb's reagent, 2,4-DNP hydrazine and vanillin sulphuric acid as spraying agents. The pungent components capsaicin, gingerol and shogaols get separated at Rf 0.32, 0.53 and 0.88 resp. in (i) and at Rf 0.1, 0.26 and 0.7 resp. in (ii).
