Coroglaucigenin, which is known to be a 3β, 14β, 19‐trihydroxy‐5α‐card‐20: 22‐enolid, was transformed into 2α, 3β, 19‐triacetoxy‐14β‐hydroxy‐5α‐card‐20 : 22‐enolid. The latter was identical with the known tri‐O‐acetyl‐19‐dihydro‐calotropagenin. The structure of calotropagenin ( 1 ) is thus established through an independent way.
