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.

摘要

对拟南芥茎中的内源性油菜素甾醇进行了研究。通过气相色谱 - 质谱联用（GC-MS）鉴定出了油菜素甾酮、6-脱氧油菜素甾酮、豆甾醇和6-脱氧豆甾醇。6-脱氧油菜素甾醇和6-氧代油菜素甾醇的同时存在表明，拟南芥中存在油菜素甾醇的早期和晚期C6氧化途径。
