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.作者: 并排上下 時(shí)間: 2025-3-24 00:56
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.
