Abstract
([)3 alpha-H-2]-, [4 alpha-H-2]- and [4 beta-H-2]-Cholesterols and [3 alpha-H-2]- and [5-H-2]-3 beta-hydroxy-5 beta-cholest-7-en-6-ones were converted with a hairy root culture of Ajuga reptans var. atropurpure a into 20-hydroxyecdysone, in which the deuterium atoms retained their original positions, thus strongly suggesting that 3 beta-hydroxy-5 be ta-cholest-7-en-6-one is an obligatory intermediate in the biosynthesi s of ecdysteroids in the plant.
