Abstract

Two-dimensional thin-layer chromatography has been used to screen plant samples for ecdysteroids. Satisfactory separations were obtained even in the presence of substantial impurities and for mixtures containing many ecdysteroids. Normal-phase silica and octadecyl silica plates were used to differentiate apolar and polar ecdysteroids, respectively. The major advantages of thin-layer chromatography are multiple detection, which enables specific detection of the ecdysteroids. Use of a small amount of water in the mobile phase in the first dimension, then a water-free mobile phase in the second dimension, can afford favorable separations.
