The structure of withacoagin, a new withanolide isolated from <I>Withania coagulans</I>, has been elucidated as (20<I>R</I>,22<I>R</I>)-5α,20-dihydroxy-1-oxowitha-2,6,24-trienolide by spectral analysis and chemical transformation to a known compound. This is the second report of a <I>Δ</I><SUP>6</SUP>-withanolide. Isolation of three known compounds, (20<I>R</I>,22<I>R</I>)-6α,7α-epoxy-5α,20-dihydroxy-1-oxowitha-2,24-dienolide, (20<I>S</I>,22<I>R</I>)-6α,7α-epoxy-5α-hydroxy-1-oxowitha-2,24-dienolide, and withaferin A, are also reported.
