IB a reoent oomnuuicatlonl from this Laboratory it was shorn that the lueeotloidal oonstituent2 mmmnein from the seeds of &mea americana L. possesses struoture I. Through the kind oo-operation of Dr. Murrell P. Morris of the U.S. Department of &riculture Experiment Station In Msyaguee, Puerto Rioo, we have obtained a supply of a yellow toxic prinoiple derived from the pulp of the fruits of the same plant, and the present report Is concerned with ite structure elucidation. Chromatographio purification of the yellow substance aud repeated recrystallisation from various solvents led to homogenous material vith a wide melting point range, apparently due to salvation. The analytical 46
