title: Identification of castasterone, 6-deoxocastasterone, typhasterol and 6-deoxotyphasterol from the shoots of Arabidopsis thaliana.
abstract: Endogenous brassinosteroids in the shoots of Arabidopsis thaliana were investigated. Castasterone, 6-deoxocastasterone, typhasterol and 6-deoxotyphasterol were identified by GC-MS. The co-occurrence of 6-deoxo-brassinosteroids and 6-oxo-brassinosteroids suggests that there are both early and late C6-oxidation pathways of brassinosteroids in A. thaliana.
