摘要：

Twelve pentacyclic triterpenes were isolated from the outer bark of river birch, Betula nigra. 3-Beta-acetoxyolean-11-oxo-12-ene-28-oic acid was isolated for the first time from a Betula species. 3-Beta-caffeatoxyolean-12-ene-28-oic acid has been spectrally characterized for the first time. 3-Beta-acetoxyolean-12-ene-28-oic acid and 3-beta-acetoxyolean-11-oxo-12-ene-28-oic acid have been demonstrated to be active as antifeedants for the Colorado potato beetle, Leptinotarsa decemlineata.
