Description
1) Due to the high molecular weight and cross-linked structure of crosslinked POvidone, it is insoluble in water but can quickly cause its network structure to expand and disintegrate when it meets water. It is widely used in medicine as a disintegrating agent of tablets, and is also widely used as a suspension stabilizer, a complexing agent of pharmaceutical ingredients, and a complexing agent of tannins and polyphenols in plant drugs.
2) Crosslinked polyvinylpyrrolidone (PVP-P) can form complexes with phenols and alkaloids, thereby removing them from plant samples, thus preventing protein modification and interference in order to determine protein content more accurately. It has also been reported that crosslinked polyethylpyrrolidone (PVP-P) can improve the activity of the enzyme.
