The structure of a new sterol isolated fromMusa sapientum has been shown by chemical and spectroscopic methods to be (24S)‐14α,24‐dimethyl‐9α,19‐cyclo‐5α‐cholest‐25‐en‐3β‐ol. In addition, several known (24S)‐24‐methyl‐Δ25‐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.
