Apr 17, 2018 Tang et al. developed an HSCCC method using a two-phase solvent system comprising ethyl acetate–n-butanol–ethanol–water (4:2:1.5:8.5, v/v/v/v) to separate six flavone C-glycosides (89–94, Fig. 12), including two novel compounds from Lophatherum gracile . HSCCC, HPCCC and CPC have also been successfully applied in the separation of ...

Mar 11, 2022 The filtrate was concentrated on a rotary evaporator to yield 1.84 g of the crude intermediate as a yellow oil. Ethanol (40 mL) and 20% NaOH (10 mL) were added to the flask and the mixture was heated at reflux for 6 h (open condenser). Most of the EtOH was removed on a rotary evaporator.

Mar 21, 2022 After the extractions, the extracts were filtered with filter paper (Unifil qualitative 80 g/m 2) and under a vacuum, then concentrated using a rotary evaporator ( 37 C), removing the water content of the co-solvent for quantification. The results were evaluated using ANOVA followed by Dunnett’s test considering a confidence level of 95% ...

Ultrafiltration - Wikipedia

Ultrafiltration - Wikipedia

Ultrafiltration (UF) is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the permeate (filtrate).
