4#alpha#-Methyl-5#alpha#, 14#beta#-ergosta-8, 24(24~1)-dien-3#beta#-ol ('triticusterol'): the first naturally occurring 14#beta#(H)-steroid

摘要

The structure of triticusterol isolated from the germ oil of wheat (Triticum aestivum L.; Gramineae) was established to be 4#alpha#-methyl-5#alpha#, 14#beta#-ergosta-8, 24(24~1)-dien-3#beta#-ol on the basis of spectroscopic data. This is the first example of a naturally occurring compound with a 14#beta#(H)-steroid skeleton.
