Morin is a yellow chemical compound that can be isolated from Maclura pomifera (Osage orange), Maclura tinctoria (old fustic) and from leaves of Psidium guajava (common guava).[1] In a preclinical in vitro study, morin was found to be a weak inhibitor of fatty acid synthase with an IC50 of 2.33 μM.[2] Morin was also found to inhibit amyloid formation by islet amyloid polypeptide (or amylin) and disaggregates amyloid fibers.

Such amyloid formation may have a role in Alzheimer's disease, as well as type 2 diabetes.[3] It may also contribute to graft failure in islet cell transplantation in type 1 diabetes.[3]

Morin can be used to test for the presence of aluminium or tin in a solution, since it forms characteristically fluorescent coordination complexes with them.
