Isolation techniques for anthocyanidin 3,5-diglucosides and their derivatives from three types of supramolecular pigments were newly developed using two SPE (Discovery DPA-6S and DSC-SCX) cartridges. Initially, malonylawobanin from commelinin supramolecular complex yielded 79.5% with 85.7% purity using DPA-6S, while DSC-SCX

Solid Phase Extraction: Reversed-Phase Methodology

Reversed-phase interaction will retain most molecules with hydrophobic character; it is very useful for extracting analytes that are very diverse in structure within the same sample.
