The structures of the isolated compounds were elucidated by analysis of the MS and NMR spectroscopic data and comparison with the literature. Compounds 1 and 2 are two new natural products, and their 1H and 13C NMR spectral data were fully assigned for the first time, with the help of2D NMR. All of the isolates were obtained from genus Sinomenium for the first time and the phenanthrene and anthraquinone are the structure type first reported from this genus plants.展开更多
