[Chemical constituents of Galium verum].
OBJECTIVE
To investigate the chemical constituents of the extract of Galium verum.


METHODS
The compounds were isolated by chromatography and identified by spectral data.


RESULTS
The eleven compounds obtained were identified as (+)-pinoresinol 4,4'-O-bis-beta-D-glucopyranoside (1), epipinoresinol (2), (+) -medioresinol (3), isorhamnetin (4), isorhamnetin 3-O-alpha-L-rhamnopyranosyl-(1-6)-beta-D-glucopyranoside (5), diosmetin (6), diosmetin 7-O-beta-D-glucopyranoside (7), quercetin-3-O-beta-D-glucopyranoside (8), ursolic acid (9), ursolic aldehyde (10) and rubifolic acid (11).


CONCLUSIONS
Compounds 1-5 and 9-11 were isolated from this genus for the first time.
