[Chemical constituents from Myricaria alopecuroides].
OBJECTIVE
To investigate the chemical constituents in the leaves and branches of Myricaria alopecuroides.


METHODS
Solvent extraction method was employed to extract and partition. The chemical constituents were isolated by column chromatography on silica gel, Sephadex LH-20, highly porous resin HP-20. The structures of the compounds were elucidated on the basis of physiochemical properties and spectral analysis.


RESULTS
Eleven compounds were isolated from this plant and identified as ellagic acid 3,3',4-trimethylether (1), ellagic acid 3,3'-dimethylether (2), isorhamnetin (3), kaempferol (4), 3, 5-dihydroxy-4-methoxybenzoic acid (5), daucosterol (6), 6,7,10-trihydroxy-8-octadecenoic acid (7), quercetin (8), gallic acid (9), palmitic acid (10), hexadecanoic acid, 2,3-dihydroxypropyl ester (11).


CONCLUSIONS
Except 8 and 9, all compounds were isolated from M. alopecuroides for the first time. Compound 1, 2, 5, 7, 10, 11 were obtained from the genus Myricaria for the frist time.
