摘要：

A new phytoecdysteroid, 24(24(1))[Z]-dehydroamarasterone B, has been isolated from seeds of Leuzea (Rhaponticum) carthamoides. It has been unambiguously identified by CIMS, C-13 NMR and H-1 NMR spectroscopy. The biological activity of the ecdysteroid has been determined in the Drosophila melanogaster, B-II bioassay. The ED50 (5.2 x 10(-7) M) is 70-fold higher than that for 20-hydroxyecdysone (7.5 x 10(-9) M). (C) 1997 Elsevier Science Ltd. All rights reserved.
