Nine compounds were isolated by silica gel and Sephadex LH-20 chromatography, together with preparative TLC and HPLC methods. By analysis of the MS and NMR spectroscopic data and comparison with those in literature, these nine compounds were identified as 3,3'-[oxybis(methylene)]bis(9-methoxy-9H-carbazole)(1), murrastifoline B(2), murrayaquinone A(3), 2,4-dimethoxyphenol(4), 1,2-dimethoxy-4-nitrobenzene(5), 3-methylanisole(6),(–)-syringaresinol-4-O-β-D-glucopyranoside(7), β-sitosterol(8), and octadecanyl-3-methoxy-4-hydroxylbenzeneacrylate(9), respectively. Among them, compounds 4–6 and 9 were described from the genus Murraya for the first time, and compounds 2–9 were isolated from M. tetramera for the first time.展开更多
采用硅胶柱层析色谱和重结晶方法对四数九里香(Murraya tetrameraHuang in Acta Phytotax.Sin.)的非挥发油成分进行分离和纯化,通过理化性质和波谱技术鉴定化合物结构。结果分离并鉴定出5个化合物:补骨脂素、槲皮素3-O-β-D-吡喃葡萄糖...采用硅胶柱层析色谱和重结晶方法对四数九里香(Murraya tetrameraHuang in Acta Phytotax.Sin.)的非挥发油成分进行分离和纯化,通过理化性质和波谱技术鉴定化合物结构。结果分离并鉴定出5个化合物:补骨脂素、槲皮素3-O-β-D-吡喃葡萄糖苷、咖啡酸、正三十一烷、正三十四烷醇。5个化合物均为首次从该植物中分离得到。展开更多
