Abstract

The known kavalactones (E)-4-methoxy-6-styryl-2H-pyran-2-one. 4-methoxy-6-(3-phenyloxiran-2-yl)-2H-pyran-2-one. 6-(1,2-dihydroxy-2-phenylethyl)-4-methoxy-2H-pyran-2-one, the three benzoic acid derivatives methyl-4-methoxy-3-(3'-methyl-2'-butenyl)benzoate and methyl 2,2-dimethyl-4-oxochroman-6-carboxylate, and a new methyl 4-methoxy-3-(3-methylbut-2-enoyl)benzoate were isolated from the ethanolic extract of Piper fuligineum. The structures of these compounds were determined by using a combination of spectroscopic methods, including 1D-and 2D-nuclear magnetic resonance spectroscopy and high-resolution mass spectrometry. This is the first report of the chemical study of P. fuligineum, and the methyl 4-methoxy-3-(3-methylbut-2-enoyl)benzoate is described as a new natural product. (AU)
