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%
OBJECTIVE
To study the chemical constituents from Solanum nigrum.
METHODS
Compounds were isolated and purified by silica gel, Sephadex LH-20 and preparative HPLC. Their structures were identified by physicochemical properties and spectral analysis.
RESULTS
Six compounds were isolated and identified
A new γ-alkylated-γ-butyrolactone, named melongenolide A (1), along with nine known compounds were obtained from the roots of Solanum melongena, and their structures were identified as melongenolide A (1), (+)-syringaresinol (2), (+)-lyoniresinol (3), 5,5'-dimethoxy lariciresinol (4),
