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 as (+)-pinoresinol (I), (+)-syringaresinol (II), (+)-medioresinol (III), scopoletin (IV), tetracosanoic acid (V) and beta-sitosterol (VI).
Conclusion:
Compounds I - III are isolated from this genus for the first time, while compounds IV and V are isolated from this plant for the first time.

Physical Properties Affecting Solubility
As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute and solvent species. Unlike solid and liquid solutes, however, there is no solute-solute intermolecular attraction to overcome when a gaseous solute dissolves in a liquid solvent since the atoms or molecules comprising a gas are far separated and experience negligible interactions. Consequently, solute-solvent interactions are the sole...
