Antitumour action: Aristoloside, aristolic acid II, aristolochic acids I, II, IV, IIIa, IVa and aristolactam IIIa (Nagasawa et al., 1997; Wang et al., 2000). 1.4.3 Aristolochia fangchi Hypotensive activity: magnoflorine (Zheng et al., 1999). 1.5 Sales and consumption About 320 tonnes of dried stems of A. manshuriensis were consumed in China in 1983 (Chinese Materia Medica, 1995). 1.6 Components with potential cancer hazard: aristolochic acids For the purpose of this monograph, unless otherwise specified, the term ‘aristolochic acids’ refers to an extract of Aristolochia species comprising a mixture of aristolochic acid I and its demethoxylated derivative, aristolochic acid II. Aristolochia species also contain the related aristolactams, which are phenanthrene cyclic amides (EMEA, 2000). In some of the older literature, it is unclear whether individual compounds or mixtures are being discussed when referring to ‘aristolochic acid’. 1.6.1 Nomenclature Aristolochic acid I Chem. Abstr.
