Abstract

Abstract: A new isocoumarin derivative 8, 5′-dihydroxy-6′-methoxy-4-phenyl-5, 2′-oxidoisocoumarin (1 ) and a new stilbenoid derivative methyl 5-hydroxy-2-(2-hydroxyphenyl)benzofuran-4-carboxylate (2 ) together with nine known compounds (3 –11 ) were isolated from the tubers of Sparganium stoloniferum Buch.-Ham.. Another stilbenoid derivative (3) and a xanthone (4) were identified as new natural products and compounds5 –10 were obtained for the first time from the genus Sparganium . All their structures were elucidated by comprehensive spectroscopic analysis and comparison with available literature information. Abstract :
