Abstract
- 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, 13C NMR and 1H NMR spectroscopy. The biological activity of the ecdysteroid has been determined in the Drosophila melanogaster BII bioassay. The ED50 (5.2 x 10(-7) M) is 70-fold higher than that for 20-hydroxyecdysone (7.5 x 10(-9) M).
