From the ethanol extract of the stems of Aristolochia manshuriensis , two new alkaloids, namely manshurienine A ( 1 ) and manshurienine B ( 2 ), were isolated together with six known compounds, i.e. , aristoloside ( 3 ), aristolochic acid I ( 4 ), aristolochic acid II ( 5 ), aristolic acid II ( 6 ), aristolochic acid IVa ( 7 ), and aristolochic acid IIIa ( 8 ). The structures of 1 and 2 were elucidated on the basis of spectroscopic methods, mainly by using 1 H‐and 13 C‐NMR spectroscopy, and the known compounds 3 – 8 were identified by comparing their physical and spectroscopic data with those of authentic data reported in the literature.
