摘　　要：Lignans are a prominent group of phenolic compounds ubiquitously present in the plant kingdom,playing a critical role in both plant physiology and human health.Structurally they are characterized by the dimerization of two phenylpropane units to attain diverse chemical configurations that contribute to their wide range of biological activities.In plants,lignans function primarily as defense molecules,protecting against pathogens,herbivores,and environmental stressors.These compounds also participate in plant growth regulation and lignification processes.From a nutritional and medicinal perspective,lignans are valued for their significant health benefits.They act as phytoestrogens,which can modulate estrogen receptors in humans,thereby offering protective effects against hormone-related diseases such as breast cancer and menopausal symptoms.Additionally,lignans possess potent antioxidant and anti-inflammatory properties,contributing to cardiovascular health and cancer prevention.This review aims to provide a comprehensive overview of the importance of lignans in plants,highlighting their chemical diversity,health-promoting properties and stress adaptation.By synthesizing recent research findings,this review underscores the significance of lignans in enhancing plant resilience under stress and human health.It explores their potential applications in the food and pharmaceutical industries.Besides,it will also focus on the widely used method for enhancing the production of these high-value secondary metabolites in plant cell cultures to meet their requirement in pharmaceutical industries.
