Three new triterpenoids, turrapubesols A–C ( 1 – 3 ), and one new sesquiterpenoid, 1 α ,4 α ‐dihydroxyeudesman‐11‐ene ( 4 ), along with 12 known terpenoids were isolated from Turraea pubescens. The structures of the terpenoids were established on the basis of extensive spectroscopic analyses and by a chemical transformation. The previous assignment of the NMR data for guaidiol ( 5 ) was corrected. Some of the triterpenoids exhibited cytotoxicity against the P‐388 cell line.
