4α-Methyl-5α,14β-ergosta-8,24 (241)-dien-3β-ol (“Triticusterol”): The First Naturally Occurring 14β(H)-Steroid.

The structure of triticusterol isolated from the germ oil of wheat (Triticum aestivum L.; Gramineae) was established to be 4α-methyl-5α,14β-ergosta-8,24(241)-dien-3β-ol on the basis of spectroscopic data. This is the first example of a naturally occurring compound with a 14β(H)-steroid skeleton.
