Chestnut kernels are often used for direct consumption; or processed to produce marron glacé, chestnut purée, and gluten-free products, while chestnut by-products (inner shell and outer shell) are treated as waste residues. Many in vivo and in vitro studies have proved how chestnut shell extract functions as an antioxidant and exhibits anticancer, anti-inflammatory, antidiabetic, and anti-obesity activities. This review introduces the main components of phenolic compounds in chestnut shells, traditional and modern extraction methods, and reported potential health effects. The aim is to have a better understanding of the functional active ingredients in chestnut shells and their value-added uses, to increase understanding of future applications of this agricultural and sideline product in the food, pharmaceutical, and cosmetic industries. PRACTICAL APPLICATIONS: In recent years, chestnut shells have become a hot research topic because of their rich bioactive ingredients. Due to the large amount of phenolic compounds in chestnut shells and their potential health functions (antioxidant, anticancer, antibacterial, anti-inflammatory, hypoglycemic, and treatment of obesity), extracts of chestnut shells have high biological value in the treatment of diseases. Therefore, this review introduces the main components of phenolic compounds in chestnut shells, traditional and modern extraction methods, and the potential health effects of these compounds. The aim of this review is to better understand the functional, active ingredients in chestnut shells and their value-added uses, and to increase understanding of future applications of this agricultural and sideline product in the food, pharmaceutical, and cosmetic industries.
板栗仁常被直接食用；也可加工成糖炒栗子、栗子泥、无麸质产品等；而板栗的副产物（内壳和外壳）则被当作废弃物处理。许多体内和体外研究已经证明了板栗壳提取物如何作为一种抗氧化剂，并具有抗癌、抗炎、抗糖尿病和抗肥胖活性。本综述介绍了板栗壳中酚类化合物的主要成分、传统和现代提取方法以及已报道的潜在健康影响。目的是更好地了解板栗壳中的功能活性成分及其增值用途，增加对未来在食品、制药和化妆品行业中应用这种农业副产物的理解。
近年来，由于板栗壳中富含生物活性成分，因此成为研究热点。由于板栗壳中酚类化合物含量丰富，且具有潜在的健康功能（抗氧化、抗癌、抗菌、抗炎、降血糖和治疗肥胖），因此板栗壳提取物在治疗疾病方面具有很高的生物价值。因此，本综述介绍了板栗壳中酚类化合物的主要成分、传统和现代提取方法以及这些化合物的潜在健康影响。本综述的目的是更好地了解板栗壳中的功能、活性成分及其增值用途，并增加对未来在食品、制药和化妆品行业中应用这种农业副产物的理解。
