Abstract Administration of [2−14C]mevalonolactone to excised leaves of Acnistusbreviflorus produced labelled withaferin A and jaborosalactone A. The former was degraded leading to the isolation of glyceric acid from C-25–C-27 of the withanolide. These carbons represented only 2 % of the total radioactivity of withaferin A. The relative radioactivity of these carbons indicated that C-26 is directly
