摘要：

Exogenously applied 24-epi-brassinolide and 24-epi-castasterone were transformed by a cell suspension culture of Ornithopus sativus to give fatty acid conjugates of 3,24-bisepi-brassinolide and 3,24-bisepi-castasterone, respectively, esterified at the 3 beta-position. The conjugates were identified by means of H-1 NMR and mass spectrometry. Lauric acid, myristic acid and palmitic acid were the acyl components for both brassinosteroid conjugate types. Nonconjugated 3,24-bisepi-brassinolide was also found for the first time in a plant system.
