摘要：

The petrol extract from leaves of Neoraputia alba yielded two flavones, in addition to sitosterol. The two new flavones were identified as: 7,8,3',4'-tetramethoxy-6,5-(2'',2''-dimethylpyran)flavone and 7,8,3',4',5'-pentamethoxy-6,5-(2'',2''-dimethylpyran)flavone. The compounds were identified by spectroscopic analysis. The structure of the first compound was confirmed by X-ray diffraction.
