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. - Key Word Index : Aristolochia longa; Aristolochiaceae; aristolochic acid derivatives; 2-(phenanthro<3,4-d>-1,3-dioxole-6-nitro-5-carboxamido)propanoic acid; aristolochic acids I, II, III and IV.
