本研究运用硅胶和Sephadex LH-20柱色谱及制备HPLC等多种分离方法对传统中药青风藤进行了化学成分研究工作,共分离得到19个化合物,通过NMR和MS数据分析,并结合文献对比,鉴定了它们的结构,包括3个菲、6个蒽醌和10个酚类成分.其中化合物1和2为两个新天然产物.借助2D NMR技术对化合物1的波谱数据进行了首次全归属,化合物2的波谱数据为首次报道.化合物1-19均首次从本属植物中分离得到,其中菲类及蒽醌类结构为该属植物中首次报道的化合物类型.“,”A phytochemical investigation on the stems and rhizomes ofSinomenium acutum led to the isolation of 19 compounds,including three phenanthrenes,six anthraquinones,and ten phenolic derivatives.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.
