A screening method using α-amylase-functionalized magnetic graphene oxide combined with high-speed counter-current chromatography was proposed and utilized to screen and separate α-amylase inhibitors from extract of Solanum nigrum. The α-amylase-functionalized magnetic graphene oxide was
Solanum cernuum is a medicinal plant widely distributed in south-east regions of Brazil and popularly used to treat several disorders. Despite their utilisation as a medicine, few studies on its chemical composition are reported. An efficient separation method for the ethyl acetate fraction was
The present work describes the evaluation of the antidepressant-like activity of the extract, fractions, and compounds obtained from the aerial parts of Solanum capsicoides. The methanolic extract (MESC) obtained by conventional maceration was partitioned with solvents of increasing polarities
Hyperoside, 3'-O-methylquercetin 3-O-β-D-galactopyranoside, astragalin and 3'-O-methylquercetin 3-O-β-D-glucopyranoside from an invasive weed Solanum rostratum Dunal were separated and purified successfully by high-speed counter-current chromatography (HSCCC) with a solvent system composed of
Aqueous two-phase flotation followed by preparative high-performance liquid chromatography was used to separate four flavonol glycosides from Solanum rostratum Dunal. In the aqueous two-phase flotation section, the effects of sublation solvent, solution pH, (NH4 )2 SO4 concentration in aqueous
