Thin-Layer Chromatography of Ecdysteroids: Detection and Identificationdysteroid analysis are described. In particular, improvements in scanning densitometers and radioactivity detectors have resulted in a versatile, rapid and quantitative technique which complements other chromatographic methods such as gas and high performance liquid chromatography. In addition, the

Selective Separation of 20,22-Dihydroxyecdysteroids from Insect and Plant Material with Immobilizedl properties of ecdysteroids, would be a considerable help in their isolation, identification and quantitative analysis. One possible strategy would be to exploit the presence of vicinal diol systems found in many, if not most ecdysteroids, either at C-2 and C-3, or at C-20 and C-22, or both.

Isolation and Characterization of a Diuretic Peptide, AP-I, from the Corpora Cardiaca of the House Csilica column packings, revealed a number of peptides which had diuretic activity. One of these peptides, AP-I, was associated with a major peak of UV absorbance. AP-I has been isolated using RP-HPLC, and the purity confirmed using a range of chromatographic procedures including: elution in differen
