To study the chemical constituents of the fruit of Aristolochia contorta. The compounds were isolated by chromatographic techniques and crystalization, the structures were elucidated by spectrum analysis. Fifteen compounds were isolated from the dry fruit of A. contorta, which were six aristolochic acids: aristolochic acid I, aristolochic acid III a, aristolochic acid IVa, aristolochic acid II, aristolochic acid III and aristolochic acid VIIa. Three aristolactams: aristololactam I, aristololactam II and aristololactam IIIa. Three phenolic acids syringic acid, vanillic acid and p-coumaric acid. Three other type compounds: pentacosane acid, beta-sitosterol and daucossterol. Aristolochic acid III, aristolochic acid VIIa, aristololactam IIIa, and penfacosane acid were isolated from A. contorta for the first time, and compounds 4-13 were isolated from the furit of A. contorta for the first time.
