[A new flavonoid glycoside from the roots and stems of Sphaerophysa salsula].
OBJECTIVE
To study the chemical constituents of Sphaerophysa salsula (Pall.) DC.


METHODS
Compounds were isolated by repeated chromatography, on silica gel and Sephadex LH-20 columns and identified by spectroscopic data (ESI-MS, 1H and 13C NMR, HSQC, HMBC).


RESULTS
Eight compounds have been isolated and identified as: isorhamnetin-3-O-[6"-(3-hydroxy-3-methylglutaroyl)-beta-D-glucopyranoside] (I), quercitrin (II), n-butyl-O-beta-D-fructopyranoside (III), nicotinic acid (IV), succinic acid (V), erythrol (VI), D-mannitol (VII), uridine (VIII).


CONCLUSIONS
Compound I is a new compound. Compounds I -VI were isolated from this genus for the first time.
