Abstract

Brassinosteroids in Japanese cedar (Cryptomeria japonica) were analyzed by GC-MS after being purified by reversed-phase HPLC. The occurrence of four stereoisomers of 23-dehydrobrassinolide, three stereoisomersof 28-homobrassinolide, and an isomer of homodolicholide was revealed. The stereochemical structures of these brassinosteroids remain undetermined, Among these, the 23-dehydrobrassinolide stereoisomers are thefirst brassinosteroids identified with an oxo group located at the C23 position. In addition, known brassinosteroids 3-dehydroteasterone, typhasterol and dolicholide were identified.
