摘 要:目的研究石竹科植物瞿麦Dianthus superbus全草的化学成分。方法利用硅胶柱、Sephadex LH-20凝胶柱和HPLC等色谱手段进行分离纯化,通过NMR、MS等光谱手段进行结构鉴定。结果从瞿麦全草石油醚萃取部位中分离得到9个化合物,分别鉴定为5-羟基-7,3′,4′-三甲氧基二氢黄酮(1)、5,3′-二羟基-7,4′-二甲氧基二氢黄酮(2)、5,4′-二羟基-7,3′-二甲氧基二氢黄酮(3)、β-菠甾醇(4)、胖大海素A(5)、(24R)-环阿屯-25-烯-3β,24-二醇(6)、(24S)-环阿屯-25-烯-3β,24-二醇(7)、豆甾-7-烯-3β-醇(8)和羟基二氢博伏内酯(9)。结论化合物1~9均为首次从瞿麦中分离得到。Objective To investigate the chemical constituents of Dianthus superbus.Methods The chemical constituents were isolated from 95% alcohol extract of D.superbus by silica gel column chromatography,Sephadex LH-20 column chromatography,and HPLC.Their chemical structures were elucidated on the basis of 1D NMR and ESI-MS spectroscopic analyses.Results Nine compounds including three flavanoids,two sterols,three triterpenes,and one γ-lactone were isolated.Their structures were identified as 5-hydroxy-7,3′,4′-trimethoxyflavanone(1),5,3′-dihydroxy-7,4′-dimethoxyflavanone(2),5,4′-dihydroxy-7,3′-dimethoxyflavanone(3),β-spinasterol(4),sterculin A(5),(24R)-cycloart-25-ene-3β,24-diol(6),(24S)-cycloart-25-ene-3β,24-diol(7),stigmast-7-en-3β-ol(8),and hydoxydihydrobovolide(9).Conclusion All the compounds(1—9) are isolated from D.superbu for the first time.
