使用荧光，PDA和质谱检测的HPLC来分析波尔多红酒的（多）苯酚含量，POM奇妙的石榴汁以及其他三种饮料，这些饮料是由100％石榴汁制成的。红酒和POM奇妙的果汁包含特征性花青素谱，后者的特征也具有Ellagitannins的存在，而前者则是Flavan-3-ols单体和procyanidin二聚体和三聚体。其他三种石榴产品都含有预期的ellagitannins，但它们的花青素曲线是红酒和石榴花青素的混合物。它们还包含Flavan-3-ol单体和procyanidin二聚体和三聚体，通常在100％石榴饮料中检测到成分。因此，基于HPLC的过程提供了一种直接的方法，可以使用源自红色葡萄的成分，访问基于石榴的产品的真实性。 （c）2012 Elsevier Ltd.保留所有权利。
HPLC with fluorescence, PDA and mass spectrometric detection were used to analyse the (poly)phenol content of a Bordeaux red wine, POM Wonderful pomegranate juice and three other beverages advertised as being made from 100% pomegranate juice. The red wine and POM Wonderful juice contained characteristic anthocyanin profiles with the latter also being characterised by the presence of ellagitannins and the former by flavan-3-ols monomers and procyanidin dimers and trimers. The three other pomegranate products all contained the expected ellagitannins but their anthocyanin profiles were a mixture of red wine and pomegranate anthocyanins. They also contained flavan-3-ol monomers and procyanidin dimers and trimers, components not usually detected in 100% pomegranate beverages. The HPLC-based procedures, therefore, provide a straight-forward means of accessing the authenticity of pomegranate-based products with the ready detection of constituents derived from red grapes.
