Xanthine oxidase inhibitory activity of extracts prepared

From different plant parts (aerial parts, leaves, flowers, fruits and roots), a total of 196 extracts were prepared by subsequent extraction with methanol and hot H2O and solvent-solvent partition of the MeOH extract yielding n-hexane, chloroform and 50% MeOH subextracts.

Extraction and purification of a plant peroxidase by

A plant peroxidase extracted from leaves of Ipomoea palmetta was partially purified by extraction using a polyethylene glycol (PEG)ammonium sulphate aqueous two-phase system (ATPS), followed by gel filtration on a Sephadex G-100 column. Variation of phase composition and NaCl concentration resulted in the desired reduction in volume of the extract and selective partitioning of the enzyme.

Centrifugal Partition Chromatography A More Streamlined

For example, these methods are integral for analyzing the chemical characteristics of a plant or plant extract. However, these methods cannot effectively be scaled to isolate compounds for medicinal use because they are costly and time-consuming. Centrifugal partition chromatography (CPC) may be an answer to these problems. What is CPC? CPC
