The phytochemical composition of Bel (Aegle marmelos) is a complex matrix. It consists of bioactive secondary metabolites. The most significant active markers are the coumarins, notably marmelosin, marmelide, and psoralen. Marmelosin is frequently highlighted in botanical research. It is the primary agent responsible for the fruit’s traditional association with gastrointestinal health. It also contains a high concentration of tannins. Furthermore, the fruit contains unique alkaloids such as aegeline and marmeline. They have been investigated for their role in supporting metabolic health. The pulp is also rich in pectin. It is a soluble dietary fiber. It acts as a natural prebiotic and contributes to the mucilaginous texture of the fruit. This mucilage is traditionally valued for its soothing effect on the digestive lining. Beyond these specialized compounds, Bel is a rich source of nutritional antioxidants. These include carotenoids, flavonoids, and phenolic acids. They support the body's natural defense against oxidative stress.
