제목 Extraction of Quercetin from Ginkgo biloba by DESs-based Monolithic Cartridge with RP-HPLC
초록 Deep eutectic solvents (DES) were synthesized with choline chloride (ChCl), template molecular monolithic (TMM) and non-DES monolithic (N-DES-M) without template, were prepared in an identical procedure. Fourier transform infrared spectrometer (FT-IR) and field emission scanning electron microscopy (FE-SEM) were used to characterize the obtained polymers. Rebinding experiment and solid-phase extraction (SPE) were used to prove the high selectivity adsorption properties of the polymers. The optimum extraction condition was found to be: ultrasonic time optimized (30 min), the volume fraction of ethanol and ratio of liquid to material (20 mL g-1). Under these conditions, the extraction yield of quercetin was 290.8 mg g-1. Purification of Ginkgo biloba extract was achieved by SPE process. The results showed DESs-based monolithic cartridge had potential for promising functional adsorption material for the purification of bioactive compounds.
