Development of high-speed countercurrent chromatography.

Advances in Chromatography, 2021
The preparative capability of the multilayer coil has been demonstrated in the separation of 1 g of the DNP amino acid mixture under the optimal operational conditions determined by the preliminary studies on short coils as described above. These centrifuge schemes are equipped with a novel flow-through mechanism which entirely eliminates the need for ...

Recycling Foam Countercurrent Chromatography

Analytical Chemistry, 2000
A new sample injection method for foam countercurrent chromatography (CCC), named the "recycle injection system", has been developed. In this system, the effluent from the liquid outlet is directly returned into the column through the sample feed line so that the sample solution is continuously recycled for repetitive foam fractionation. The utility of

Preparative Isolation of Piceatannol Derivatives from Passion Fruit (Passiflora edulis) Seeds by High-Speed Countercurrent Chromatography Combined with High Performance Liquid Chromatography and Screening for α-Glucosidase Inhibitory Activities.

Journal of Agricultural and Food Chemistry, 2020
Passiflora edulis Sims (Passion fruit) seeds are often discarded as by-products during juice processing. In fact, the seeds are of considerable commercial value in food and cosmetics industry because of their rich polyphenols, especially piceatannol.
