Characterization and preparation of oligomeric procyanidins from Litchi chinensis pericarp.
Fitoterapia. 2016 Jul; 112:168-74.F

Abstract

The main purpose of this study is to characterize and prepare A-type oligomeric procyanidins from litchi pericarp (Litchi chinensis Baila). The variety of oligomeric procyanidins was characterized by LC-ESI-MS analysis. There were (+)-catechin, (-)-epicatechin, twelve dimers and six trimers of procyanidins were found in litchi pericarp extracts, and A-type procyanidins were much more abundant than B-type procyanidins. The main flavan-3-ol monomer and oligomeric procyanidins in litchi pericarp were (-)-epicatechin, A-type dimers (A1 and A2) and trimer (epicatechin-(4β-8, 2β-O-7)-epicatechin- (4β-8)-epicatechin). Procyanidin A1 (epicatechin-(4β-8, 2β-O-7)-catechin) was identified by NMR in litchi pericarp for the first time. (-)-Epicatechin and oligomeric procyanidins were prepared by the combination of AB-8 column chromatography and Toyopearl HW-40S column chromatography. The results showed that each fraction predominantly owned a single compound and gave a high yield with (-)-epicatechin, A-type dimers (A1 and A2) and trimer, suggesting a useful method to obtain pure (-)-epicatechin and A-type oligomeric procyanidins.
