Organic solvents were widely used for extraction of bioactive compounds from different functional foods and nutraceuticals. However, the involvement of toxic and volatile organic solvents causes significant environmental problems. In order to overcome the shortages, non-ionic surfactant-assisted extraction was proposed as an alternative, effective, cheap and green extraction method. By considering...
New ionic liquid-modified silica sorbents were developed by the surface chemical modification of the commercial silica using synthesized ionic liquids. The obtained ionic liquid-modified particles were successfully used as a special sorbent in solid-phase extraction process to isolation of cryptotanshinone, tanshinone I and tanshinone IIA from Salvia Miltiorrhiza Bunge. Different washing and elution...
