Abstract 2-(Phenanthro[3,4- d ]-1,3-dioxole-6-nitro-5-carboxamido)propanoic acid, a new aristolochic acid derivative, was isolated as the methyl ester from roots of Aristolochia longa . The known aristolochic acids III (as its corresponding methyl ester), I, II and IV were also characterized, the latter being isolated for the first time in the free form.
