Abstract
A new brassinosteroid, (22R,23R,24S)-22,23-dihydroxy-24-methyl-5 alpha -cholestan-3,6-dione (6) which is termed 3-dehydroteasterone, as well as castasterone (2), typhasterol (3), teasterone (4), and 6-deoxocasta sterone (5) were identified from wheat (Triticum aestivum L.) grains b y GC-MS. In addition, the presence of a castasterone epimer and a pair of 6-deoxocastasterone epimers was indicated, although their structur es remain undetermined. 3-Dehydroteasterone is considered to be an int ermediate in the conversion of teasterone to typhasterol.
