Comprehensive structural analysis of polyphenols and their enzymatic inhibition activities and antioxidant capacity of black mulberry (Morus nigra L.).

In this paper, the structures of polyphenols and their bioactivity of black mulberry (Morus nigra L.) cv. 'Heisang No.

Structure, degree of polymerization, and starch hydrolase inhibition activities of bird cherry (Prunus padus) proanthocyanidins.

The structure of proanthocyanidins extracted from bird cherry fruits was characterized by HPLC-ESI/MS and MALDI-TOF/MS analyses, and their subunits and mean degree of polymerization (mDP) were investigated by thiolysis reaction, and the inhibition activity against starch hydrolases measured using the high-throughput turbidity assay. This is the first mass spectrometric analysis to thoroughly investigate the structure and mDP of proanthocyanidins in bird cherry fruits. Bird cherry proanthocyanidins were categorized as oligomeric proanthocyanidins (mDP = 5.
