Abstract
The structure of a new 14α‐methylsterol isolated fromCucumis sativus has been shown to be (24R)‐14α‐methyl‐24‐ethyl‐5α‐cholest‐9(11)‐en‐3β‐ol. Characterization of the 14α‐methyl‐Δ9(11) skeletal structure was undertaken based on the comparison with 14α,24‐dimethyl‐5α‐cholest‐9(11)‐en‐3β‐ol obtained from 24‐methylpollinastanol by acid‐catalyzed isomerization. Isolation and identification of an additional 14α‐methylsterol, 24‐methylene‐pollinastanol, from the plant also is described.This publication has 15 references indexed in Scilit:
