Mulberry (Morus sp.) fruits provide high levels of anthocyanins, quercetin glycoside, and chlorogenic acid. Recently, mulberry’s polyphenols and their functionalities are spotlighted in different ex vivo and in vivo studies. Meanwhile, the deficiency of systematic knowledge on the health effects and polyphenols composition greatly hinders the development of mulberry as a sustainable fruit. This review briefly summarises the polyphenol compositions, metabolism, health benefits, and their stability in different mulberry production steps. These claimed health effects include anti-oxidative, anti-cancer, anti-diabetes, anti-obesity, and other related effects. However, although the current evidence is promising, further clinical studies are needed to evaluate the role of mulberries' polyphenols to support human health. Besides, the mechanisms by which they confer the health benefits, the bioavailability studies on mulberry’s polyphenols are also scarce. We compile the research findings from the available literatures within the last two decades, and we also suggest some future perspectives in this review.

桑树（桑属）果实可提供高水平的花色苷，槲皮素糖苷和绿原酸。近日，桑的多酚及它们的功能备受瞩目在不同的体外和体内学习。同时，对健康影响和多酚成分的系统知识的缺乏极大地阻碍了桑as作为可持续水果的发展。这篇综述简要总结了不同桑生产步骤中的多酚组成，代谢，健康益处及其稳定性。这些声称的健康影响包括抗氧化，抗癌，抗糖尿病，抗肥胖和其他相关影响。然而，尽管目前的证据是有希望的，但仍需要进一步的临床研究来评估桑berries中多酚对人类健康的作用。此外，由于桑蚕多酚具有健康益处的机理，对它们的生物利用度研究也很少。我们汇总了过去二十年中现有文献的研究结果，
