[Study on chemical constituents isolated from Juncus effuses].
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).


CONCLUSIONS
Compound II, III, V, VI, VII, VIII were firstly isolated from this plant.
