中文摘要:
      采用硅胶柱色谱、Sephadex LH-20凝胶柱色谱、半制备HPLC等方法对箭根薯(Tacca chantrieri Andre)的地上部分的化学成分进行了研究,从中分离到12个化合物. 其中化合物1为一个新的二氢查耳酮化合物,通过一维、二维核磁共振、高分辨质谱、红外、紫外以及多种波谱手段来确定其结构为1-(1,3-benzodioxol-5-yl)-3-(2,4-bimethoxyphenyl)-1-propanone (1). 通过波谱学数据及理化性质确定其他已知化合物的结构分别为:1-(3,4-dimethoxyphenyl)-3-(2,4,6-trimethoxyphenyl)-1-propanone (2), alusenone (3), erythrabyssin II (4), phaseolin (5), warangalone (6), (2S)-5-hydroxy-7,3?,4?-trimethoxyflavan (7), (2S)-5-hydroxy-7,3?,5?-triamethoxyflavan (8), (2S)-4?-hydroxy-5,7,3?-triamethoxyflavan (9), diosgenin (10), stigmasterol (11)和cycloneolitsol (12).
英文摘要:
      Using gel column chromatography (CC), Sephadex LH-20, and semi-preparative HPLC, the chemical research of the aerial part of Tacca chantrieri have been studied, which led to the isolation of twelve compounds. Among them, compound 1 was a new dihydrochalcone and its structure was established as 1-(1,3-benzodioxol-5-yl)-3-(2,4-bimethoxyphenyl)-1-propanone (1) according to its 1D and 2D NMR data as well as MS, IR, and MS spectra. On basis of spectroscopic analysis and comparison with literatures, the known compounds were determined as 1-(3,4-dimethoxyphenyl)-3-(2,4,6-trimethoxyphenyl)-1-propanone (2), alusenone (3), erythrabyssin II (4), phaseolin (5), warangalone (6), (2S)-5-hydroxy-7,3?,4?-trimethoxyflavan (7), (2S)-5-hydroxy-7,3?,5?-triamethoxyflavan (8), (2S)-4?-hydroxy-5,7,3?-triamethoxyflavan (9), diosgenin (10), stigmasterol (11), and cycloneolitsol (12).
