OBJECTIVE
To study the constituents isolated from Juncus effuses Linn..
METHODS
The compounds were isolated through chromatographic approaches, such as Silica gel. CC, Sephadex LH-20 and were identified by a combination of spectroscopic methods (UV, MS, 1H-NMR, 13C-NMR and NOE).
RESULTS
8 kinds of compounds were identified which included four flavonoids, luteolin (I), eriodictyol (II), 2', 5', 5, 7-tetrahydroxyflavone (III), glucoluteolin (IV); two aromatic compounds, methyl p-hydroxybenzoate (V), vanillic acid (VI); a fatty acid, hexadecanoic acid (I) and an alkane, n-Tetradecane (VIII).
CONCLUSION
Compound II, III, V, VI, VII, VIII were firstly isolated from this plant.
目的
研究灯心草中分离出的成分。
方法
通过硅胶柱色谱、葡聚糖凝胶LH - 20等色谱方法分离化合物，并结合紫外光谱（UV）、质谱（MS）、氢核磁共振（1H - NMR）、碳核磁共振（13C - NMR）和核Overhauser效应（NOE）等光谱方法进行鉴定。
结果
鉴定出8种化合物，其中包括4种黄酮类化合物，木犀草素（I）、圣草酚（II）、2',5',5,7 - 四羟基黄酮（III）、木犀草素葡萄糖苷（IV）；2种芳香族化合物，对羟基苯甲酸甲酯（V）、香草酸（VI）；1种脂肪酸，十六烷酸（VII）和1种烷烃，正十四烷（VIII）。
结论
化合物II、III、V、VI、VII、VIII首次从该植物中分离得到。
