A new ionic liquid-based silica sorbent was developed by a process involving surface chemical modification of commercial silica using a synthesized ionic liquid. The obtained particles were successfully used as a special sorbent in a solid-phase extraction process to isolate liquiritin and glycyrrhi

Biocatalytic systems can be used for the regio-and stereospeciΓc synthesis of oxidized alkanes and aromatic compounds, such as aliphatic and aromatic alcohols, aldehydes and epoxides. These reactions are typically carried out in two-liquid phase media. The biocatalyst is usually a natural microorgan
