Four new prenylated flavonoids, sinoflavonoids NF–NI (1–4), were isolated from the fruits of Sinopodophyllum hexandrum by different chromatographic methods such as silica gel, Sephadex LH-20, ODS, and preparative high-performance liquid chromatography (HPLC). Their structures were elucidated on the basis of extensive spectroscopic data (UV, IR, HR-ESI-MS, 1H NMR, 13C NMR, HSQC, HMBC).
