Detection and result The chromatogram was dried in a stream of warm air. Blood-red fluorescent chlorophyll zones were visible in the region of the solvent front. In the case of Orthosiphon leaf extract there was an intense pale blue fluorescent sinensetin zone OiRf 90-95) immediately below this, followed by a series of usually weaker blue fluorescent zones extending right down to the start zone (Fig. lA).
