Abstract
OBJECTIVE: Chemical constituents of the non-saponins from Solonum nigrum L. were studied. METHODS: The separation was performed on the silic gel CC, Sephadex-LH20 CC as well as preparative HPLC. The constituents were isolated and identified by spectral methods. RESULTS: Five compounds isolated from 60% ethanol extract werre identified as 6-methoy-hydroxycoumarin (I), syringaresinol-4-O-beta-D-glucopyranoside (II), pinoresinol-4-O-beta-D-glucopyranoside (III), 3, 4-dihydroxhbenzoic acid (IV), p-hydroxybenzoic acid (V), 3-methoxy-4-hydroxyienzoic acid (VI), adenosine (VII). CONCLUSION: II, III, and VII were isolated from this genus for the first time.
