Abstract
Seven phragmalin limonoids of swietephragmins A-G, and two other different types of 2-hydroxy-3-O-tigloylswietenolide and deacetylsecomahoganin, were isolated along with three known limonoids from the leaves of Swietenia mahogani (Meliaceae). Their structures were determined by spectroscopic methods.
