3'-Hydroxyamentoflavone and Its 7-O-Methyl Ether, Two New Biflavonoids from Aristolochia contorta

Two new biflavonoids, 3'-hydroxyamentoflavone-7-O-methyl ether (1) and 3'-hydroxyamentoflavone (2), were isolated from the fruits of Aristolochia contorta Bge. Their structures were elucidated by HR-ESI-MS, 1D-, and 2D-NMR spectroscopy.
