[Lignans from stems of Sambucus williamsii].
OBJECTIVE
To study the chemical constitutents of the 60% ethanol extract of the stems of Sambucus williamsii.


METHODS
Compounds were isolated and purified by Diaion D101, silica gel,Sephadex LH-20, ODS column chromatography and preparative HPLC. Their structures were identified by spectroscopic methods.


RESULTS
Seven lignans were isolated and identified as erythro-guaiacylglycerol-beta-O-4'-sinapyl ether (1), 1-( 4'-hydroxy-3'-methoxyphenyl) -2- [4"-( 3-hydroxypropyl) -2", 6"-dimethoxyphenoxy] propane-1,3-diol (2), isolariciresinol (3), burselignan (4), lyoniresinol (5), 5-methoxy-isolariciresinol (6), cycloolivil (7).


CONCLUSIONS
All these compounds were obtained from this genus for the first time.
