Scopoletin (7-hydroxy-6-methoxycoumarin), a coumarin, was isolated from the aerial part of Solanum lyratum Thunb. by the activity-guided fractionation employing carbon tetrachloride-intoxicated primary cultured rat hepatocytes as a screening system. Its hepatoprotective activity was first evaluated
Activity-guided fractionation of the ethanol extract of the whole plant from Solanum lyratum resulted in the isolation of a new pregnane derivative glycoside, 16-dehydropregnenolone 3-O-alpha-L-rhamnopyranosyl-(1 --> 2)-beta-D-glucopyranosid uronic acid (2), as well as other six known compounds:
Solavetivone (1), cytotoxic to OVCAR-3 cells with an IC(50) value of 0.1 mM, has been isolated from Solanum indicum. In addition, a novel solafuranone (2) and three known compounds, scopoletin, N-(p-trans-coumaroyl)tyramine, and N-trans-feruloyltyramine, were isolated for the first time from this
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
Solanum xanthocarpum is considered an important traditional medicinal herb because of its unique antioxidant, and anti-diabetic, anti-aging, and anti-inflammatory potential. Because of the over exploitation linked to its medicinal properties as well as destruction of its natural habitat,
