摘要：
Exogenously applied 24-epi-castasterone and 24-epi-brassinolide are transformed in a multi-step metabolic process by cell suspension cultures of Ornithopus sativus to give 2 alpha,3 beta,6 beta-trihydroxy-5 alpha-pregnane-20-one and 2 alpha,3 beta-dihydroxy-B-homo-7-oxa-5 alpha-pregnane-6,20-dione, respectively, as the major metabolites. This is the first report concerning a catabolic side-chain degradation of brassinosteroids in plant material.
