Qualitative Analysis of Oligomeric Procyanidins from Litchi chinensis Pericarp
摘要
Abstract
Litchi （Litchi chinensis Sonn.） is a subtropical fruit of high commercial value; however, its pericarp results in a reduced market value. In the present study, oligomeric procyanidins from Litchi chinensis pericarp （LPOPC） were prepared and qualitatively analyzed. LPOPC were extracted with ethanol aqueous solution, purified by AB-8 macroporous resin chromatography, and fractionated by Toyopearl HW-40S resin chromatography to obtain LPOPC. LPOPC was found to comprise three fractions with different degrees of polymerization （DP）. The results of FT-IR, HPLC and LC-MS analyses revealed that the major components of LPOPC were （-）-epicatechin, procyanidin A2, procyanidin A3. Highly pure monomer, dimmers and trimers were obtained through selective collection of fractions.关键词
