摘要：

Two new triterpenes have been isolated from Amberboa ramosa. Their structures were established as (22R)-cycloart-25-ene-3beta,22-diol [1] and cycloart-20-ene-3beta,25-diol [2] through chemical and spectroscopic studies including 2D nmr. Two known triterpenes, cycloartanol and cycloart-23-ene-3beta,25-diol, were also isolated.
