This paper describes composition of dried plums and their products (prune juice and dried plum powder) with special attention to possibly bioactive compounds. Dried plums contain significant amounts of sorbitol, quinic acid, chlorogenic acids, vitamin K1, boron, copper, and potassium. Synergistic action of these and other compounds, which are also present in dried plums in less conspicuous amounts, may have beneficial health effects when dried plums are regularly consumed. Snacking on dried plums may increase satiety and reduce the subsequent intake of food, helping to control obesity, diabetes, and related cardiovascular diseases. Despite their sweet taste, dried plums do not cause large postprandial rise in blood glucose and insulin. Direct effects in the gastrointestinal tract include prevention of constipation and possibly colon cancer. The characteristic phenolic compounds and their metabolites may also act as antibacterial agents in both gastrointestinal and urinary tracts. The indirect salutary effects on bone turnover are supported by numerous laboratory studies with animals and cell cultures. Further investigation of phenolic compounds in dried plums, particularly of high molecular weight polymers, their metabolism and biological actions, alone and in synergy with other dried plum constituents, is necessary to elucidate the observed health effects and to indicate other benefits.
本文描述了李子干及其产品（李子汁和李子干粉）的组成，特别关注可能具有生物活性的化合物。李子干含有大量的山梨糖醇、奎宁酸、绿原酸、维生素 K1、硼、铜和钾。这些化合物以及其他以不太明显的量存在于李子干中的化合物的协同作用，可能会对健康产生有益影响，如果定期食用李子干的话。吃李子干零食可能会增加饱腹感，减少随后的食物摄入，有助于控制肥胖、糖尿病和相关心血管疾病。尽管李子干味道甜美，但它们不会导致餐后血糖和胰岛素大幅升高。在胃肠道中的直接作用包括预防便秘和可能的结肠癌。特征性酚类化合物及其代谢物也可能在胃肠道和泌尿道中充当抗菌剂。大量动物实验和细胞培养研究支持对骨转换的间接有益作用。需要进一步研究李子干中的酚类化合物，特别是高分子量聚合物，以及它们的代谢和生物作用，单独以及与其他李子干成分协同作用，以阐明观察到的健康影响并指出其他益处。
