After feeding of 24-epi-castasterone to the cockroach Periplaneta americana
an organ-specific epimerization of the brassinosteroid to 2,24-diepi-casta
sterone could be detected in female insects. The metabolite being observed
only in the ovaries and not in the testes of the insect was identified by G
C/MS in comparison with a synthesized authentic sample. Contrary, 24-epi-br
assinolide is not metabolized in the sexual organs of Periplaneta americana
. This is the first evidence of a metabolic transformation of a brassinoste
roid in insects.
