title: Isolation and identification of three ecdysteroid conjugates with a C-20 hydroxy group in eggs of Locusta migratoria.
abstract: Three ecdysteroids conjugates with a hydroxy group at C-20 were isolated from developing eggs of locusta migratoria and identified as 22-phosphate conjugates of 2-deoxy-20-hydroxy-ecdysone, 20-hydroxyecdysone and 20-hydroxyecdysone acetate.
