- A pentacyclic triterpenoid of rare occurrence, characterised as bauerenol acetate by NMR and mass spectral and by formation of its derivatives, has been isolated in good yield (·003% in leaves and·40% in bark) from the neutral fractions of the petroleum extracts of the leaves and stem-bark of Ervatamia wallichiana Steub. (Fam. Apocynaceae).
