From the ethereal extract of Melilotus neapolitana Ten., an herbaceous plant living in the Mediterranean macchia, a new aromatic metabolite was isolated. The structure l-(2,4-dihydroxyphenyl)2-(4-hydroxy-2-methoxyphenyl)l,3- propandiol, was elucidated on the basis of its mass spectrum and ID and 2D NMR spectroscopic data (DQ-COSY, TOCSY, HSQC, HMBC). The relative configuration was determined from NOESY/ROESY experiments and computational calculations. The compound was tested for its potential allelopathic effect on two wild plant species living in the same habitat as M. neapolitana.

Abstract
From the ethereal extract of Melilotus neapolitana Ten., an herbaceous plant living in the Mediterranean macchia, a new aromatic metabolite was isolated. The structure l-(2,4-dihydroxyphenyl)2-(4-hydroxy-2-methoxyphenyl)l,3- propandiol, was elucidated on the basis of its mass spectrum and ID and 2D NMR spectroscopic data (DQ-COSY, TOCSY, HSQC, HMBC). The relative configuration was determined from NOESY/ROESY experiments and computational calculations. The compound was tested for its potential allelopathic effect on two wild plant species living in the same habitat as M. neapolitana.File in questo prodotto:
