Definition
ChEBI: 20-hydroxyecdysone is an ecdysteroid that is ecdysone substituted by a hydroxy group at position 20. It has a role as a plant metabolite and an animal metabolite. It is a 20-hydroxy steroid, an ecdysteroid, a 14alpha-hydroxy steroid, a 3beta-sterol, a 2beta-hydroxy steroid, a 22-hydroxy steroid, a 25-hydroxy steroid and a phytoecdysteroid. It is functionally related to an ecdysone.
l?uterung methode
Crystallise -ecdyson from water, tetrahydrofuran/pet ether, MeOH and EtOAc after chromatographic purification. It has max (EtOH) at 240nm ( 12,670 M-1cm-1). [Also IR & NMR: Hüppi & Siddall J Am Chem Soc 89 6799 1967, Kametani et al. Tetrahedron Lett 21 4855 1980, Beilstein 8 IV 343.]
