Brassinosteroids are of ubiquitous occurrence in plants and elicit a wide spectrum of physiological responses. In our study, brassinosteroids were isolated and identified in topmost dormant leaves of tea plants. Six brassinosteriods, i.e. 6-deoxocastasterone, 24-epibrassinolide, 3-dehydroteasterone, typhasterol, 3-deoxotyphasterol and 28-homodolicholide, were isolated and identified by GC-MS. All the brassinosteroids identified belong to important components of early and late C6 oxidation pathways proposed for brassinosteroids biosynthesis in plants. It suggests that both pathways are operating in tea to produce brassinolide, the most active brassinosteroid biologically.
