儿茶素，属于类黄酮类的化合物，对人体健康有潜在的益处。为了能够对这些化合物进行流行病学评估，需要关于其在食品中含量的数据。采用高效液相色谱法结合紫外和荧光检测，测定荷兰24种水果、27种蔬菜和豆类、一些主食和加工食品中的（+）-儿茶素、（-）-表儿茶素、（+）-没食子儿茶素（GC）、（-）-表没食子儿茶素（EGC）、（-）-表儿茶素没食子酸酯（ECg）和（-）-表没食子儿茶素没食子酸酯（EGCg）水平。大多数水果，巧克力和一些豆类含有儿茶素。含量差别很大：从猕猴桃中的4.6毫克/千克到黑巧克力中的610毫克/千克。（+）-儿茶素和（-）-表儿茶素是主要的儿茶素; GC、EGC和ECG在一些食物中检测到，但没有食物含有EGCg。本文报道的数据为儿茶素对慢性病风险影响的流行病学评价提供了基础。
Catechins, compounds that belong to the flavonoid class, are potentially beneficial to human health. To enable epidemiological evaluation of these compounds, data on their contents in foods are required. HPLC with UV and fluorescence detection was used to determine the levels of (+)-catechin, (-)-epicatechin, (+)-gallocatechin (GC), (-)-epigallocatechin (EGC), (-)-epicatechin gallate (ECg), and (-)-epigallocatechin gallate (EGCg) in 24 types of fruits, 27 types of vegetables and legumes, some staple foods, and processed foods commonly consumed in The Netherlands. Most fruits, chocolate, and some legumes contained catechins. Levels varied to a large extent: from 4.6 mg/kg in kiwi fruit to 610 mg/kg in black chocolate. (+)-Catechin and (-)-epicatechin were the predominant catechins; GC, EGC, and ECg were detected in some foods, but none of the foods contained EGCg. The data reported here provide a base for the epidemiological evaluation of the effect of catechins on the risk for chronic diseases.
