Four new compounds were isolated from the aerial parts of Aristolochia constricta (Aristolochiaceae). Their structures were elucidated on the basis of spectral and chemical data to be 10-amino-1-carboxy-3,4-dimethoxy-6-hydroxyphenanthrene lactam N-β-D-glucopyranoside; 10-amino-1-carboxy-3,4-dimethoxy-6-hydroxyphenanthrene lactam N-β-D-(6'-trans-p-coumaroyl)-glucopyranoside; 10-amino-1-carboxy-3,4,6-trimethoxyphenanthrene lactam N-β-D-glucopyranoside, 10-amino-1-carboxy-3,4,6-trihydroxyphenanthrene lactam N-β-D-glucopyranoside.
