摘要：

The bark wood ofAustroplenckia populnea afforded, in addition to 3-hydroxy-2-oxofriedelan- 3-ene-20α-methylcar{ballot box}ylate, methyl populnonate, 3-hydroxy-2-oxofriedelan-3-ene-20α-car{ballot box}ylic acid, populnonic acid, epikatonic acid, dispermoquinone, β-sitosterol, β-sitostenone and dulcitol, two new pentacyclic triterpenes: 3-oxoolean-12-ene-20α-car{ballot box}ylic acid and 3β-hydroxy-2- oxofriedelan-20α-car{ballot box}ylic acid. The structures of these have been established from spectral studies and structural correlations, and single-crystal X-ray analysis of 3β-hydroxy-2-oxofriedelan- 20α-car{ballot box}ylic acid. © 1990 Pergamon Press plc.
