The structure of a new sterol isolated from Musa sapientum has been shown by chemical and spectroscopic methods to be (24 S)-14α,24-dimethyl-9α,19-cyclo-5α-cholest-25-en-3β-ol. In addition, several known (24 S)-24-methyl-Δ-sterols, their 24-methylene isomers and other sterols (4,4-dimethyl-, 4α-methyl- and 4-demethyl-sterols) together with 3-oxo-4α-methylsteroids were isolated from the plant and identified. The biogenetic implication of these sterols and 3-oxosteroids is discussed. [ABSTRACT FROM AUTHOR] |
