许多体外和体内研究表明，膳食花青素和鞣花单宁或鞣花酸可能具有有益的健康效果。由于缺乏关于这些多酚在食品中含量的可靠数据，因此缺乏关于这些多酚预防疾病潜力的流行病学证据。在这项研究中，分析了花青素和鞣花单宁（酸水解后的鞣花酸当量）的含量在芬兰消费的食品，包括浆果，水果，蔬菜和加工产品，使用高效液相色谱（HPLC）方法。在54种食品中，41种检出花青素。总花色素苷的含量在浆果中为1至611 mg/100 g，在水果中为2至66 mg/100 g，在蔬菜中为3至75 mg/100 g鲜重（以糖苷配基的重量计）。在33种食品中检出鞣花单宁，但仅在云莓、树莓、玫瑰果、草莓和沙棘等5种浆果中检出，含量范围为1 ~ 330 mg/100 g。结果强调了浆果的优越性，特别是深蓝色或红色浆果，作为花青素的优良来源，蔷薇科的某些浆果作为芬兰饮食中鞣花单宁的主要来源。
Numerous in vitro and in vivo studies have suggested that dietary anthocyanins and ellagitannins or ellagic acid might have beneficial health effects. Epidemiological evidence on the disease-preventing potential of these polyphenols is lacking, due to the absence of reliable data on their contents in foods. In this study was analyzed the content of anthocyanins and ellagitannins (as ellagic acid equivalents after acid hydrolysis) in foods consumed in Finland, including berries, fruits, vegetables, and processed products, using high-performance liquid chromatographic (HPLC) methods. Anthocyanins were detected in 41 of 54 selected food items. The total anthocyanin content varied in berries from 1 to 611 mg/100 g, in fruits from 2 to 66 mg/100 g, and in vegetables from 3 to 75 mg/100 g of fresh weight as the weight of the aglycone. Ellagitannins were screened in 33 food items, but were detected only in 5 species of berries, that is, in cloudberry, raspberry, rose hip, strawberry, and sea buckthorn, the content ranging from 1 to 330 mg/100 g. The results underscore the superiority of berries, especially dark blue or red berries, as excellent sources of anthocyanins and certain berries of the Rosaceae family as the major source of ellagitannins in the Finnish diet.
