摘要：

Brassinosteroids (BRs) contained in rice (Oryza sativa L.) bran were extracted and highly purified. A new BR, (22R,23R,24S)-3 alpha,22,23-trihydroxy-24-ethyl-5 alpha-cholestan-6-one, which is termed 28-homotyphasterol, was identified by GC-MS, in addition to 28-homoteasterone and 6-deoxocastasterone.
