Abstract
En 中文
Lablab purpureus (hyacinth bean) is a multifaceted legume traditionally integrated into diverse food systems and sustainable agricultural practices, particularly in Asia and Africa. Known for its adaptability to harsh environments, nitrogen-fixing ability, and use as both food and fodder, this crop holds untapped potential for addressing modern nutritional and health challenges. Recent scientific investigations have brought L. purpureus into the spotlight due to its impressive phytochemical profile, which includes phenolics (phenolic acids and flavonoids). These constituents are associated with a wide range of therapeutic properties, such as antioxidant, antimicrobial, anti-inflammatory, antidiabetic, and hepatoprotective activities. Nutritionally, L. purpureus is rich in proteins, essential amino acids, dietary fiber, vitamins, and minerals, making it a valuable candidate for combating malnutrition and enhancing food security, particularly in regions with limited access to diverse food sources. Furthermore, its functional properties suggest promising applications in nutraceutical and pharmaceutical product development. However, despite these attributes, L. purpureus remains largely underutilized and insufficiently represented in mainstream agricultural, food, and biomedical research. This review consolidates and synthesizes current knowledge on the phytochemical composition, nutritional value, and therapeutic potential of L. purpureus, while also identifying critical knowledge gaps and research priorities. By drawing attention to this overlooked legume, the review encourages greater scientific interest and investment in its study and application. As global demand grows for plant-based functional foods and sustainable crop alternatives, L. purpureus presents itself as a viable, eco-friendly, and health-promoting resource worthy of renewed focus and broader utilization across multiple sectors.
