Adsorption and Purification of Baicalin from Scutellaria baicalensis Georgi Extract by Ionic Liquids (ILs) Grafted Silica.

ABSTRACT: Baicalin which has multiple biological activities is the main active component of the root of Scutellaria baicalensis Georgi (SBG). Although its isolation and purification by adsorption methods have aroused much interest of the scientific community, it suffered from the poor selectivity of the adsorbents. In this work, an environmentally benign method was developed to prepare ionic liquids (ILs) grafted silica by using IL 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C₄mim]NTf₂) and ethanol as reaction media. The IL 1-propyl-3-methylimidazolium chloride ([C₃mim]Cl) grafted silica ([C₃mim]⁺Cl^-@SiO₂) was used to adsorb and purify baicalin from the root extract of Scutellaria baicalensis</
