Feeding of [13C2]acetate to hairy roots of Ajuga reptans var. atropurpurea followed by 13C-NMR analysis of the biosynthesized cholesterol and 20-hydroxyecdysone indicated that C-25 hydroxylation in 20-hydroxyecdysone biosynthesis mechanisms. Feeding studies of [26-13C]- and [27-13C]cholesterols established that the ratio of retention and inversion mechanisms is ca. 3:1.
