ABSTRACT
From stem barks of Capuronianthus mahafalensis (Meliaceae) endemic to Madagascar, a new protolimonoid named capulin containing a four membered ring in its side chain was isolated by repeated silica gel column chromatography. Its structure was determined by 1D and 2D NMR spectroscopy and high-resolution MS. To the best of our knowledge, this is the first time that a four-membered ring occurs in the side chain of protolimonoids.
