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 25 ‐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.
