Summary

Descripción general del contenido del recurso.

In connection with our continuous investigation of Piper species, we have isolated 2-methoxy- 4,5-methylenedioxypropiophenone from the roots of Piper murginatum. The literature reported the same compound isolated from leaves of the same species, but only <sup>1</sup>H NMR (60 MHz), UV, IV and EM were used in spectroscopic assignments. In the present paper we assign unambiguously the protons and carbons peaks with the assistance of 1D and 2D NMR experiments. En relación al trabajo de investigación desarrollado en especies pertenecientes al género Piper, hemos aislado 2-metoxy-4,5-metilendioxipropiofenona a partir de las raíces de Piper marginatum. La literatura cita el mismo compuesto en hojas de la misma especie, pero en la asignación estructural solamente fueron utilizados <sup>1</sup>H RMN (60 MHz), UV, IV y EM en las atribuciones estructurales. En el presente trabajo asignamos sin ambigüedades los valores de los desplazamientos químicos de hidrógenos y carbonos con la ayuda de experimentos de RMN en una y dos dimensiones (ID y 2D).
